Understand performance issues with NN emulator #38

Closed andreufont closed 1 year ago

andreufont commented 1 year ago

The emcee sampling is very significantly slower when using the NN emulator, not sure why.

Actually, just importing the nn_emulator module causes the script to be several factors slower.

It looks like the problem was scikit_learn, that was actually not used anyway. Removed that, it seems to be working fine now, so I'm closing the issue.
