Proper installation guidelines

[samvelyan]

The users should be able to run the framework following ONLY the installation guide.

I think easiest to use via conda.

hard veto on conda - i think this is all pip installable!

[akbir]

like we don’t need auto install binaries so feels like conda is overkill

@newtonkwan - can you update the install details and look at making pax a package?

[samvelyan]

what does pip-installable have to do with having conda environments for your py projects?

[akbir]

So the way I see it, conda is a system package manager vs pip is a python package manager.

You should use conda (or suggest it to users) when you need to install things that are not just in python. For example - torch or opencv, where the dependencies are C++ binaries or other libraries (e.g. libjpeg-turbo).

Just like most other packages in the Jax eco-system you don't need to specify any additional binaries (e.g evosax, Chex, rlax) - the user is assumed to have jax already installed. I think it would be good to keep to that standard.
