Installation of dm-acme fails based on PyPI issue with dependency rlax

[siggiorn]

Following the pip installation instructions from the README I get the following error:

ERROR: Packages installed from PyPI cannot depend on packages which are not also hosted on PyPI.
dm-acme depends on rlax@ git+git://github.com/deepmind/rlax.git#egg=rlax

It seems that you are attempting to install dm-acme==0.2.1 but I think the latest release is 0.2.2. Maybe try to install without using the cache?

pip install --no-cache-dir 'dm-acme' 'dm-acme[jax]' 'dm-acme[tensorflow]'

Thanks for the suggestion, it led to some discoveries.

pip install --no-cache-dir 'dm-acme' does in fact work and installs the latest version of 0.2.2.

However pip install --no-cache-dir 'dm-acme[jax]' ends up downloading dm-acme-0.2.1.tar.gz which gets the error above about rlax.

If I request the latest version with pip install --no-cache-dir 'dm-acme[jax]==0.2.2' then I get a different error:

ERROR: Could not find a version that satisfies the requirement dm-reverb; extra == "jax" (from dm-acme[jax]) (from versions: none)
ERROR: No matching distribution found for dm-reverb; extra == "jax"

which led me to see from https://github.com/deepmind/reverb that reverb isn't supported on my platform, OSX, so that error is expected.
