Issue importing keras-rl on tensorflow-macos about keras-rl HOT 4 OPEN

Hi, I've had some problems with keras-rl and tensorflow and I managed to find a solution to this problem, after hours of trying to figure it out. Hopefully it works for you too.

keras-rl works with tensorflow 1.X, from my understanding, and keras-rl2 is supposed to fix that by requiring tensorflow>=2.1.0. Unfortunately, keras-rl2 is archived, so there can't be anymore fixes. My solution was this:

1. Download the keras-rl2 source code from here
2. Go into setup.py and remove the install_requirements=['tensorflow'], line OR you can even change it to tensorflow-macos
3. Follow the install instructions from source code from here (the keras-rl2 instructions are incomplete)

Once you install keras-rl2 your problems should dissapear.

My issues here these:

• ERROR: Could not find a version that satisfies the requirement tensorflow (from keras-rl2) (from versions: none) when trying to install keras-rl2
• ERROR: when trying to do pip install keras-rl2==1.0.5
  Keras symbolic inputs/outputs do not implement __len__. You may be trying to pass Keras symbolic inputs/outputs to a TF API that does not register dispatching, preventing Keras from automatically converting the API call to a lambda layer in the Functional Model. This error will also get raised if you try asserting a symbolic input/output directly.

Hopefully this helps.
