Adding Feature Extractors

[joaogui1]

I think adding the feature extractors from SB3 is a good next step towards feature parity between the libraries

Hello,
thanks for the proposal, achieving full feature parity is not my priority for now (as SBX is meant to be experimental) but I would welcome such PR =)

Small update, I added CNN support for DQN: #49

I don't think separating fully features extractor and actor net would make sense for SBX.

Hello, is supporting CnnPolicy for PPO planned or actively ongoing? Or should I create a Pull Request?

Hello,

Or should I create a Pull Request?

Please open a PR =)
This should be similar to #49

[yhs0602]

Thank you for the quick response! Got it, I’ll work on opening a PR when I get the chance.

PPO CNN support is coming: #81
