All of them are suffixed with an EOS token (``) that has index = 2 in SPM-200's dictionary. + +`idx` files contain number of tokens per sentence from the `bin` file (including the `` token) per line, aka a single number per line. + +The language code just before the `.bin`/`.idx` suffix tells us about the processed language in that particular file (i.e. are these English or Turkish sentences). + +## Step 2 +Next up we load the data from the above `bin`/`idx` files into `mmap` or memory mapped dataset. + +TL;DR: `mmap` helps us to deal with datasets whose size can't fit in system memory (RAM). It automagically handles loading from the disk so that you don't have to think about RAM utilization yourself. + +It's the lowest level of abstraction and it deals with headers, pointers and bytes from `.bin` & `.idx` files. + +You can find its implementation in the `MMapIndexedDataset` class. + +## Step 3 +We then wrap the `mmap` dataset for both the source and the target language into `PrependTokenDataset`. + +As the name suggests it prepends the lang tokens to all src & trg tokenized sentences (token here means a number/index in the SPM dictionary not something like `_an`). + +Language tokens look something like `__hin_Deva__` and have their own corresponding index in the SPM dictionary. + +So at this point the source/target sentence might look something like: `260058 230 392 22050 2` (format = (`lang token` = 260058, `data tokens` = 230 392 22050, `` = 2). + +## Step 4 +We then wrap the source/target `PrependTokenDataset` datasets into `LanguagePairDataset` abstraction. + +## Step 5 +We then wrap multiple `LanguagePairDataset`s (for every lang direction we are training on) into `SampledMultiDataset`. + +This dataset additionally assigns a sampling ratio to each of its `LanguagePairDataset` subsets - based on the size of the subset. +For example if one subset has 75M sentences and the other one 25M the sampling coefficients will be 0.75 and 0.25 respectively (unless we modify the temperature). That means we'll be sampling 3x more data from the bigger subset (proportionally). + +But if we change the temperature from 1 to something above/below it - it also computes the "virtual size" of the dataset now that we’ve potentially upsampled (or downsampled) some of the lang-direction subsets. + +*Note on virtual size: as an example if we have 2 lang directions one with 1M and one with 0.5M sentences and temperature > 1 then the virtual size is basically 1M + 0.5M*c, where c is a coefficient larger than 1. Thus we end up with a virtual size that's bigger than 1.5M sentences (we will effectively duplicate certain sentences from that smaller subset).* + +It finally pre-computes all of the indices for this particular epoch for the virtual dataset and creates a random permutation of those indices. + +## Step 6 +Next we wrap `SampledMultiDataset` into `EpochBatchIterator`. + +At the end of the `get_train_iterator` function (which both loads `SampledMultiDataset` dataset and instantiates the `EpochBatchIterator`) we call `self.reset_dummy_batch(batch_iterator.first_batch)` which in return triggers `first_batch` function to be called which in return calls `frozen_batches` (`len` operator acting as the trigger) and finally that function subsequently calls the batch sampler which does the following 2 operations: + +a) sorts the virtual dataset indices by target & source sample sizes in that particular order. + +b) filters out the samples that are too long (> `512`) (either source/target). + +c) batches/chunks the indices from a) such that the total number of source/target tokens in a batch (including the padding) is below `max_tokens` specified by our input training arguments. This is done in the `batch_by_size_vec` function. + +## Step 6.1 - note on collation +`first_batch` function (mentioned above called as a part of `self.reset_dummy_batch`) triggers the collation procedure for the dummy batch - which is effectively the first time that our code calls into the data pipeline. + +The process looks like the following: +* We iterate through the indices of the first batch (as determined by the output of `dataset.batch_by_size` function all). +* For each of those indices we index into `SampledMultiDataset` which internally delegates that index to the right `LanguagePairDataset` which then further delegates that call to the underlying source/target `mmap` datasets. From there we fetch the "raw" tokens which are then prepended with the language token (in `PrependTokenDataset`) and finally `SampledMultiDataset` propagates that information upward in a form of a dictionary with 3 keys: `id`, `source`, `target`. +* Next up `SampledMultiDataset`'s collate function is triggered and internally it delegates this call further to `LanguagePairDataset`'s collate function. +* The collate function extracts the `source` (`target`) tensors from each of those sample dictionaries. Finds the max sequence length and creates a tensor of dimension `num_samples` x `max_{src/trg}_len` initialized with `pad` tokens. +* That resulting tensor is then populated with source/target tokens applying left/right padding respectively. +* Finally we create another tensor (`prev_output_tokens`) that is the exact copy of the target tensor with the ony difference that the `` "EOS" token is swapped so that it's now the first token in those sequences (effectively they are using "EOS" token as a BOS token as well - i.e. start/beginning of sequence token). This is the tensor that we feed into the decoder and we compare its outputs against the `target` tensor. +* The collate function finally returns a dictionary: +``` + batch = { + "id": id, + "nsentences": len(samples), + "ntokens": ntokens, + "net_input": { + "src_tokens": src_tokens, + "src_lengths": src_lengths, + "prev_output_tokens": prev_output_tokens, + }, + "target": target, + } +``` + +And this is exactly what you end up seeing if you take a look at our data loading loops for either training or validation. Now you understand exactly how the whole process works in the background (almost - see the next couple of steps! :)). + +## Step 7 +Once we have retrieved `EpochBatchIterator` from step 6, we call the `next_epoch_itr` function on it and it does the following steps: +* It shuffles the `frozen_batches`'s (mentioned before as being a property of `EpochBatchIterator`) rows. Frozen batches (which is a list of lists of indices) is arranged in such a way that its first rows contain indices of the shortest samples in our dataset. Thus those first indices lead to a construction of batches that have a large amount of short sentences. As we progress through its rows the batches end up having less and less sentences and are longer in length. Basically going from left to right and top to bottom across its indices we get progressively longer sentence pairs. +* Shards the indices across different GPUs on our system (by wrapping the shuffled batch into `ShardedIterator`). If you have `n` GPUs on your system, the first GPU will take out 0th, (n-1)-first, 2*(n-1)-st ... rows from the shuffled batch. + +Note from @gordicaleksa: I think it might be better to first shard and then shuffle because doing it like this, in the worst case scenario, we might end up having a much larger work load on one of the GPUs. Because for example all of the "wide" batches end up on that GPU (i.e. small batch size long sentences). + +## Step 8 +The sharded shuffled batches are then passed into `PyTorch’s dataloader` together with `SampledMultiDataset` and its collator function. + +## Step 9 +All of the above is then wrapped into a `CountingIterator` which just does what the name suggests: keeps track of the number of consumed batches during the training (or validation - similar pipeline there). + +## Step 10 +Finally `CountingIterator` object is wrapped into in a progress bar (e.g. `WandBProgressBarWrapper` + `JsonProgressBar`). Those just +do some additional logging (to the console and/or Weights & Biases dashboard) and then delegate the call to the `CountingIterator`. + +Note: Only the main/master GPU (the one that has a global rank == 0) process will log to Weights & Biases. +The other GPU processes won't have that additional wandb progress bar wrapper instead they'll only have e.g. JSON bar wrapper. + +--- + +Some additional context: all of this is a part of the `TranslationMultiSimpleEpochTask`. \ No newline at end of file diff --git a/GETTING_STARTED.md b/GETTING_STARTED.md new file mode 100644 index 0000000000..171cb392f0 --- /dev/null +++ b/GETTING_STARTED.md @@ -0,0 +1,135 @@ +# Getting started with Open-NLLB 🚀 + +There are 5 different components to Open-NLLB system, and thus 5 different areas where you could potentially contribute!

Just [follow these INSTALL instructions](INSTALL.md) to build the Python environment that you can also then re-use for Open-NLLB. + +Check out [this README](https://github.com/gordicaleksa/Open-NLLB-stopes/tree/nllb_replication/stopes/pipelines/filtering) for more information on how to run the filtering stage. + +TL;DR: the high-level workflow is the following: +* Run the `download_parallel_corpora.py` script which downloads our primary bi-text and formats it. +* Run 3 different Python scripts (see the README above for more details) to create all of the necessary filtering config files. +* After you have this data and configs run the filtering pipeline that uses various heuristics like line length based filtering and pairwise deduplication to filter out lower quality bi-text. +* With the filtered data ready you can then proceed to the next stage (data preparation). + +## 4. Data preparation + +**Setup:** Install the [Open-NLLB-stopes](https://github.com/gordicaleksa/Open-NLLB-stopes) project. Just [follow these INSTALL instructions](INSTALL.md) to build the Python environment that you can also then re-use for Open-NLLB. + +Check out [this README](https://github.com/gordicaleksa/Open-NLLB-stopes/tree/nllb_replication/stopes/pipelines/prepare_data) for more information on how to run the data preparation stage. + +TL;DR: the high-level workflow is the following: +1. (Optional) Run the filtering stage - data preparation can also work directly on "raw" bi-text (i.e. w/o filtering) +2. Run the `prepare_extra_configs.py` to create data preparation config file. +3. Modify `prepare_data.yaml` config to setup the data preparation stage linking to the config from the previous step. +4. The data preparation stage will then do the following: + - Validation checks - makes sure that all bi-text source/target files have the same number of lines. + - Concatenates the data from all the datasets for a particular language direction (e.g. `eng_Latn-rus_Cyrl` might exist in datasets `A`, `B`, and `C` and so we concat all 3 of those files into a final one). + - Deduplicates across all language directions and then shards the language direction files into smaller pieces. + - Binarizes the shards using the pre-trained `SPM-200` tokenizer. + +## 5. Model training + +**Setup:** Install the [Open-NLLB](https://github.com/gordicaleksa/Open-NLLB) project. Just [follow these INSTALL instructions](INSTALL.md) to build the Python environment that you can also then re-use for Open-NLLB-stopes. + +*Note: if you've already run the setup for any of the previous two stages you don't need to do this.* + +To run the training you have 2 options: +1. (Better for local runs) For local runs (non-slurm runs) you can run the [`train.py`](fairseq_cli/train.py) directly just use the config provided below as the starting point / reference. + +Context: I got that config by running the [`train_script.py`](examples/nllb/modeling/train/train_script.py) following [its README](examples/nllb/modeling/README.md) and then extracting the settings that that script passes on to `train.py` (I just traced out the code path that led to it). + +2. (Better when running on slurm) Run [`train_script.py`](examples/nllb/modeling/train/train_script.py) and follow [its README](examples/nllb/modeling/README.md) to get started. + +Also check out [this README](/home/aleksa/Projects/nllb/fairseq/fairseq_cli/README.md) for more information (on how to setup Weights & Biases, etc.). + +The reference train config: +``` + "--distributed-world-size", "2", "/home/aleksa/Projects/nllb/stopes/stopes/pipelines/prepare_data/processed_data/data_bin/shard000:/home/aleksa/Projects/nllb/stopes/stopes/pipelines/prepare_data/processed_data/data_bin/shard001", + "--save-dir", "/home/aleksa/Projects/nllb/fairseq/model_checkpoints/save_dir", + // "--tensorboard-logdir", "/home/aleksa/Projects/nllb/fairseq/model_checkpoints/tb/tb_log", + "--skip-invalid-size-inputs-valid-test", "--memory-efficient-fp16", "--max-update", "100000", + "--update-freq", "1", "--task", "translation_multi_simple_epoch", "--lang-pairs", "eng_Latn-spa_Latn,eng_Latn-rus_Cyrl,tur_Latn-rus_Cyrl", + "--use-local-shard-size", "--sampling-method", "temperature", "--sampling-temperature", "1", + "--adam-eps", "1e-06", "--adam-betas", "(0.9, 0.98)", "--lr-scheduler", "inverse_sqrt", + "--warmup-init-lr", "1e-07", "--warmup-updates", "500", "--lr", "5e-05", "--stop-min-lr", "1e-09", + "--clip-norm", "0.0", "--dropout", "0", "--weight-decay", "0.0", + "--criterion", "label_smoothed_cross_entropy", "--label-smoothing", "0.1", + "--best-checkpoint-metric", "nll_loss", "--max-tokens", "2048", "--seed", "2", "--log-format", "json", + "--log-interval", "100", "--validate-interval-updates", "500", // "--valid-subset", "valid", + "--keep-interval-updates", "1", "--keep-last-epochs", "1", "--validate-interval", "1000", + "--max-source-positions", "512", "--max-target-positions", "512", "--enable-m2m-validation", + "--add-data-source-prefix-tags", "--share-all-embeddings", "--decoder-normalize-before", + "--encoder-normalize-before", "--optimizer", "adam", "--fp16-adam-stats", "--min-params-to-wrap", + "100000000", "--ddp-backend", "fully_sharded", "--replication-count", "1", "--encoder-langtok", "src", + "--decoder-langtok", "--langs", "/home/aleksa/Projects/nllb/fairseq/examples/nllb/modeling/scripts/flores200/langs.txt", + "--save-interval-updates", "1000", "--save-interval", "1000", "--arch", "transformer", "--encoder-layers", "12", + "--decoder-layers", "12", "--encoder-ffn-embed-dim", "4096", "--decoder-ffn-embed-dim", "4096", "--encoder-embed-dim", + "1024", "--decoder-embed-dim", "1024", "--encoder-attention-heads", "16", "--decoder-attention-heads", "16", + "--attention-dropout", "0.1", "--relu-dropout", "0.0", "--train-subset", "train", + "--wandb-project", "open-nllb", "--disable-validation" +``` + +Notes: +* Modify `--distributed-world-size` depending on the number of GPUs you have on your system (I have 2, set to 1 if only single GPU) +* I removed some of the sharded paths (I have 28 of them and so will you if you download all of the primary data) just to make it more readable +* Modify `"--lang-pairs"` depending on which directions you want to train for +* Modify `"--max-tokens", "2048"` depending on the amount of VRAM you have.

The disclaimer of warranties and limitation of liability provided + above shall be interpreted in a manner that, to the extent + possible, most closely approximates an absolute disclaimer and + waiver of all liability. + +Section 6 -- Term and Termination. + + a. This Public License applies for the term of the Copyright and + Similar Rights licensed here. However, if You fail to comply with + this Public License, then Your rights under this Public License + terminate automatically. + + b. Where Your right to use the Licensed Material has terminated under + Section 6(a), it reinstates: + + 1. automatically as of the date the violation is cured, provided + it is cured within 30 days of Your discovery of the + violation; or + + 2. upon express reinstatement by the Licensor. + + For the avoidance of doubt, this Section 6(b) does not affect any + right the Licensor may have to seek remedies for Your violations + of this Public License. + + c. For the avoidance of doubt, the Licensor may also offer the + Licensed Material under separate terms or conditions or stop + distributing the Licensed Material at any time; however, doing so + will not terminate this Public License. + + d. Sections 1, 5, 6, 7, and 8 survive termination of this Public + License. + +Section 7 -- Other Terms and Conditions. + + a. The Licensor shall not be bound by any additional or different + terms or conditions communicated by You unless expressly agreed. + + b. Any arrangements, understandings, or agreements regarding the + Licensed Material not stated herein are separate from and + independent of the terms and conditions of this Public License. + +Section 8 -- Interpretation. + + a.

It aims to help people communicate with anyone, anywhere, regardless of their language preferences. + +To enable the community to leverage and build on top of NLLB, we open source all our evaluation benchmarks(FLORES-200, NLLB-MD, Toxicity-200), LID models and training code, LASER3 encoders, data mining code, MMT training and inference code and our final NLLB-200 models and their smaller distilled versions, for easier use and adoption by the research community. + +This code repository contains instructions to get the datasets, optimized training and inference code for MMT models, training code for LASER3 encoders as well as instructions for downloading and using the final large NLLB-200 model and the smaller distilled models. +In addition to supporting more than 200x200 translation directions, we also provide reliable evaluations of our model on all possible translation directions on the FLORES-200 benchmark. By open-sourcing our code, models and evaluations, we hope to foster even more research in low-resource languages leading to further improvements in the quality of low-resource translation through contributions from the research community. + + + +- [Paper](https://research.facebook.com/publications/no-language-left-behind/) +- [Website](https://ai.facebook.com/research/no-language-left-behind/) +- [Blog](https://ai.facebook.com/blog/nllb-200-high-quality-machine-translation/) +- [NLLB Demo](https://nllb.metademolab.com/) +- [Request for Proposals : Translation Support for African Languages](https://ai.facebook.com/research/request-for-proposals/translation-support-for-african-languages/) + + + +## Open Sourced Models and Community Integrations + +### Multilingual Translation Models +| Model Name | Model Type | #params | checkpoint | metrics | +| - | - | - | - | - | +| NLLB-200 | MoE | 54.5B |[model](https://tinyurl.com/nllb200moe54bmodel) | [metrics](https://tinyurl.com/nllb200moe54bmetrics), [translations](https://tinyurl.com/nllbflorestranslations) | +| NLLB-200 | Dense | 3.3B |[model](https://tinyurl.com/nllb200dense3bcheckpoint) | [metrics](https://tinyurl.com/nllb200dense3bmetrics) | +| NLLB-200 | Dense | 1.3B |[model](https://tinyurl.com/nllb200dense1bcheckpoint) | [metrics](https://tinyurl.com/nllb200dense1bmetrics) | +| NLLB-200-Distilled | Dense | 1.3B | [model](https://tinyurl.com/nllb200densedst1bcheckpoint) | [metrics](https://tinyurl.com/nllb200densedst1bmetrics) | +| NLLB-200-Distilled | Dense | 600M | [model](https://tinyurl.com/nllb200densedst600mcheckpoint) | [metrics](https://tinyurl.com/nllb200densedst600mmetrics) | + +All models are licensed under CC-BY-NC 4.0 available in [Model LICENSE](LICENSE.model.md) file.

we trained for NLLB-200. These neural multilingual machine translation models support translation between any pair of [200 languages](scripts/flores200/langs.txt). Not only do we support more than 200x200 translation directions, we also release the [quality](#open-sourced-models-and-metrics) of our final model on each of the 200x200 translation directions by measuring spBLEU and chrf++ on the [FLORES-200 benchmark](https://github.com/facebookresearch/flores). In the sections below, we share where our models can be downloaded, how they can be used for inference or finetuning, and more details about how to train your own multilingual machine translation models with Sparsely Gated Mixture of Experts, Expert Output Masking, Curriculum Learning, incorporating self-supervised learning (denoising auto-encoder like mBART), Online Distillation.

Additional Information +

+With Hydra, options are configured via [Hydra](https://hydra.cc/docs/intro/), and used with configuration files are provided: + + +* Training: [`train/conf/cfg/default.yaml`](train/conf/cfg/default.yaml) +* Evaluation: [`evaluation/conf/generate_multi.yaml`](evaluation/conf/generate_multi.yaml) + +

+
+ + +### Filtering and Preparing the Data + +Data preparation is managed by the [stopes](https://github.com/facebookresearch/stopes) library. Specifically: + +1. Data filtering is performed using `stopes` corpus filtering pipeline. Please consult the filtering pipeline’s README file and example configuration for more details. +2. Once filtered, data can then be preprocessed/binarized with the prepare_data pipeline in `stopes`. Please consult the README file for further information. + + +## Training various NLLB models + +We provide scripts for training the NLLB-200 model and other variants. They launch training using train_script.py, which is configured using Hydra (similar to generation/evaluation). The default configuration can be found at [`train/conf/cfg/default.yaml`](train/conf/cfg/default.yaml), and the training configs we include are `flores_200_full`, `flores_200_full_moe`, `flores_200_ablation`, `flores_200_ablation_moe`, and `flores_200_ablation_ssl`.

@@ +# Helper scripts for NLLB Modeling + +## `generate_backtranslations.sh` + +This script takes a binarized, sharded monolingual corpus and backtranslates it. The script will look for the binarized monolingual corpus under `${MONODIR}/data_bin/shard{000,001,...}/*.{bin,idx}`. We split the monolingual corpus into shards as jobs on slurm may fail or be pre-empted, and this allows us to restart individual shards when it they fail rather than having to redo the whole corpus. + +The script will take care of re-running any shards that are incomplete – all you have to do is run it again with the same arguments. To detect whether a shard was not fully backtranslated, it will compare the number of lines in the output with the number of lines in the input (using the utility script `count_idx.py`). If the translated lines are >95% of the input lines, the shard is considered complete. Otherwise, the incomplete outputs will be deleted and the shard will be re-run. *NB*: Make sure all backtranslation jobs are complete before re-running the script with the same arguments – jobs that are still running will otherwise be mistaken by the script as having failed. + +Before running the script please make sure you populate these variables in the script: +* `$MODEL`: The path to the model checkpoint file. +* `$MODEL_LANGS`: The list of languages supported by the model, in the same order they were passed during training on fairseq. +* `$MONODIR`: The path to the monolingual data directory. +* `$OUTDIR`: The path to the output directory where you want to store the generated backtranslations. + + +Example command: +``` +examples/nllb/modeling/scripts/generate_backtranslations.sh x_en awa_Deva,fra_Latn,rus_Cyrl +``` + +Parameters: +* The first argument is whether the backtranslation generation is from or out of english, `en_x` or `x_en` respectively. +* The second argument is the list of languages to generate backtranslations for, a comma separated string of lang names. Eg: `awa_Deva,fra_Latn,rus_Cyrl` + +## `extract_fairseq_bt.py` + +This command takes BT shard outputs and extracts a parallel corpus from them. +It optionally can perform some very basic filtering of the sentences, but generally a +more complete filtering pipeline should be used, e.g. the one included in the +[STOPES](https://github.com/facebookresearch/stopes) library. + +Example command to run locally: +``` +python extract_fairseq_bt.py --local-run --directions eng_Latn-fuv_Latn \ + --strip-orig-tag --spm-decode $SPM_MODEL_FOLDER/sentencepiece.model \ + --corpus-name test_corpus \ + $BASE_FOLDER +``` +Parameters: +* `$BASE_FOLDER` is where the script looks for BT shard outputs, specifically under `$BASE_FOLDER/$direction/*_{0..999}.out` +* `--output-folder` is where the script will place filtered outputs, specifically: `$output_folder/$direction/$corpus_name.$lang.gz`. +* `--spm-decode` tells the model to perform SPM decoding using the provided model on both the original and backtranslated text. +* `--directions` is a space-separated list of language pairs. They are interpreted as `$bt_lang-$original_lang` (`$original_lang` corresponds to `S-*` lines in fairseq's output, and `$bt_lang` to `H-*` lines). +* To run on SLURM, remove the `--local-run` flag. You may additionally want to specify `--slurm-partition` and `--slurm-timeout`. +* See `--help` for further information. + + +## `extract_moses_bt.py` + +This command is analogous to `extract_fairseq_bt.py` above, but for data translated with +MOSES. It can additionally perform some very basic MOSES-specific filtering (based on the ratio of copied tokens). + +Example command to run locally: +``` +python extract_moses_bt.py --local-run --directions eng_Latn-fuv_Latn \ + --detruecase $MOSES_FOLDER/scripts/recaser/detruecase.perl \ + --spm-decode $SPM_MODEL_FOLDER/sentencepiece.model \ + --corpus-name test_corpus \ + $BASE_FOLDER +``` + +Parameters: +* `$BASE_FOLDER` is the location of input and output shards. The script expects them in `$BASE_FOLDER/{src_sharded,tgt_sharded}/$direction/$lang.{000..999}`. +* Filtered outputs will be placed in `$output_folder/$direction/$corpus_name.$lang.gz`. +* `--detrucase` tells the script to perform detruecasing on both the original and backtranslated shards. You will need to pass the location of the MOSES `detruecase.perl` script. +* `--directions` is interpreted as in `extract_fairseq_bt.py`. +* To run on SLURM, remove the `--local-run` flag. You may additionally want to specify `--slurm-partition` and `--slurm-timeout`. +* See `--help` for further information. + +## `count_idx.py` + +This is a utility script to count the number of sentences in a fairseq binarized dataset (`.idx` file). +It's used by `generate_backtranslations.sh` to figure out which shards of a corpus have been fully backtranslated. diff --git a/examples/nllb/modeling/scripts/backtranslation/count_idx.py b/examples/nllb/modeling/scripts/backtranslation/count_idx.py new file mode 100644 index 0000000000..f6e25c6d5f --- /dev/null +++ b/examples/nllb/modeling/scripts/backtranslation/count_idx.py @@ -0,0 +1,15 @@ +# Copyright (c) Meta Platforms, Inc. and affiliates. +# All rights reserved. + +# This source code is licensed under the license found in the +# LICENSE file in the root directory of this source tree. + +import struct +import sys + +assert len(sys.argv) == 2 + +with open(sys.argv[1], "rb") as f: + assert f.read(9) == b"MMIDIDX\x00\x00" + _ = f.read(9) + print(struct.unpack(" 0 and min_len < args.min_len: + filter_stats.min_len_filtered += 1 + return None + if args.max_len > 0 and max_len > args.max_len: + filter_stats.max_len_filtered += 1 + return None + if args.max_len_ratio is not None and max_len / min_len > args.max_len_ratio: + filter_stats.len_ratio_filtered += 1 + return None + + #
