The tensorflow-macos branch is currently archived so I was hoping someone could help me find a fix for this Import error. Im trying to import keras-rl packages and its throwing errors because TensorFlow does not have a function that keras uses during import. Idk if there's a previous version of keras-rl that would fix this or if I'm kinda just boned until TensorFlow has proper support for the m1 chip. logs below, package versions listed from pip also below. (run on a jupyter notebook and a minforge/conda venv)

jupyter-client 7.0.2
jupyter-core 4.7.1
jupyterlab-pygments 0.1.2
tensorflow-addons-macos 0.1a3
tensorflow-estimator 2.5.0
tensorflow-macos 0.1a3
keras 2.6.0
keras-rl 0.4.2

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.
