Failure to precompile in Julia 1.7.1

[daler6]

After installing Julia 1.7.1., I receive the following error when trying to use ScikitLearn:

[ Info: Precompiling ScikitLearn [3646fa90-6ef7-5e7e-9f22-8aca16db6324]

Ouch, PRs are appreciated... Thank you for the report.

I am not able to reproduce but did have a different issue that was resolved with

import Conda
Conda.update()

You may have to add Conda to your environment.

I believe I am using the python installation private to julia (ENV["PYTHON"] is not defined). Do you know what installation you are using (what is ENV["PYTHON"] for you?).
