Very easy. `pl.from_numpy` and `series.to_numpy` are your friend here. For 1D columns, we often can be zero copy as well. Besides that we support numpy ufuncs for `Series` and `Expressions`. As OP pointed out: https://kevinheavey.github.io/modern-polars/performance.html... Numpy can be used to speed up some functions by utilizing numpy ufuncs. Numpy drops the GIL and therefore they can still be executed in parallel. |
