Where to download 0.2.0_4 wheel?

On the homepage, I can only find 0.2.0_3 wheel for pip. I need 0.2.0_4 to import lr_scheduler.

I don’t think there’s a 0.2.0_4 wheel. If you want to use that version (or if you just want lr_scheduler), you could try installing from conda and/or building from source.
