Flet can't run certain libraries

Describe the bug
I'm trying to get scikit-learn to run but it causes an error. All other libraries are running fine. It runs well in my ide but once compiled causes an error. So far I have tested for Windows, android and webapp. The windows is executable when packaged with pyInstaller. Hope this error can be sorted out
