Hello !
when running example code for LazyFrame with polars > 1.17.0 I got the following error (for 1.10-1.17 it works ok):

RuntimeError: BindingsError: "Error when deserializing LazyFrame. This may be due to mismatched polars versions. Semantic(None, \"unknown variant `b`, expected one of `Filter`, `Cache`, `Scan`, `DataFrameScan`, `Select`, `GroupBy`, `Join`, `HStack`, `Distinct`, `Sort`, `Slice`, `MapFunction`, `Union`, `HConcat`, `ExtContext`, `Sink`, `IR`\")"

(venv) ➜  extend_polars_python_dispatch git:(main) ✗ pip list | grep polars
extend_polars 0.1.0   /Users/mwiewior/research/git/pyo3-polars/example/extend_polars_python_dispatch/extend_polars
polars        1.18.0
