Hi,

I need to run sklearn.metrics library which is not available in Julia yet.  
I tried to run on my macbookpro M1 but I run into this issue:

Anybody managed to make it work on mac?

Thank you for your help

Sounds like you have a broken Python installation. I would `rm("/Users/alexdunant/.julia/conda", recursive=true)` and try again.
