Hello @spinningwatt is it possible for you to upgrade to scikit_learn_intelex-2024.1.0-py311-none-win_amd64.whl? Could you also give the output of pip show tbb daal daal4py

I can't reproduce this issue with 2024.0.1 and 2024.1.0 versions of sklearnex. The only visible difference is usage of Windows 11 with conda pkgs manager on my side.

notice: I have even tried to put all the dll files to c:\python312\dlls, where other dll files are stored. and the issue is the same.

Hi @fantasydog, which windows version are you running?

Hi @fantasydog @spinningwatt
Can you please share the results of running the conditionals here in your environment:
https://github.com/intel/scikit-learn-intelex/blob/main/onedal/__init__.py#L22-L38
I have not been able to reproduce this issue on my own machine but the dll is located in the redist path instead of the lib/intel64 which is added by default during build. I am curious if one of these conditions is not met and results in the dlls not being visible.
