Migration off defaults to conda-forge channel (facebookresearch#4126)
Summary: Good resource on overriding channels to make sure we aren't using `defaults`:https://stackoverflow.com/questions/67695893/how-do-i-completely-purge-and-disable-the-default-channel-in-anaconda-and-switch Explanation of changes: - - changed to miniforge from miniconda: this ensures we only pull in from conda-defaults when creating the environment - architecture: ARM64 and aarch64 are the same thing. But there is no miniforge package for ARM64, so we need to make it check for aarch64 instead. However, mac breaks this rule, and does have macOS-arm64! So there is a conditional for mac to use arm64. https://github.com/conda-forge/miniforge/releases/ - mkl 2022.2.1 change: conda-forge and defaults have completely different dependencies. Defaults required intel-openmp, but now on conda-forge, mkl 2023.1 or higher requires llvm-openmp >=14.0.6, but this is incompatible with the pytorch build <2.5 which requires llvm-openmp<14.0. We would need to upgrade Python to 3.12 first, upgrade Pytorch build, then upgrade this mkl. (The meta.yaml changes are the ones that narrow it to 2022.2.1 during `conda build faiss`.) So, this has just been changed to 2022.2.1. - mkl now requires _openmp_mutex of type "llvm" instead of "gnu": prior non-cuVS builds all used gnu, because intel-openmp from anaconda defaults channel does not require llvm-openmp. Now we need to remove the gnu one which is automatically pulled in during miniconda setup, and only keep the llvm version of _openmp_mutex. - liblief: The above changes tried to pull in liblief 0.15. This results in an error like `AttributeError: module 'lief._lief.ELF' has no attribute 'ELF_CLASS'`. When I checked passing PR builds on defaults, they use lief 0.12, so I pinned that one. - gcc_linux-64 =11.2 for faiss-gpu on cudatoolkit-11.2: this build kept trying to reference 11.2 when 14.2 was installed. Current builds still reference 11.2, so I gave up and pinned 11.2 to keep it the same. Moving to 14.2 will take some more investigation. - conda_build_config.yaml: I removed Python 3.12 because the build fails with the below error. Python 3.12 also doesn't really work (facebookresearch#3936) I think? So I removed it. ``` INTEL MKL ERROR: $PREFIX/lib/python3.12/site-packages/faiss/../../.././libmkl_def.so.2: undefined symbol: mkl_sparse_optimize_bsr_trsm_i8. Intel MKL FATAL ERROR: Cannot load libmkl_def.so.2. ``` Differential Revision: D68043874
