Keras-rl2==1.0.3 not compatible with any current hosted tensorflow

[Travis-Barton]

Hey all,

We are trying to run through the example: https://poke-env.readthedocs.io/en/latest/rl_with_open_ai_gym_wrapper.html#rl-with-open-ai-gym-wrapper

however, when we run the file, we get:

ValueError: Tensor Tensor("dense_2/BiasAdd:0", shape=(None, 22), dtype=float32) is not an element of this graph.

This is caused (we think) by the fact that we weren't using Keras-rl2==1.0.3. So we tried to downgrade but now Keras-rl2==1.0.3 is no longer compatible with TensorFlow 2.7 (it wants TensorFlow==2.0.0-beta however this is no longer hosted). Any idea what a workaround could be?

Hey @Travis-Barton,

Thanks for opening this issue, and sorry for the delay. I will try to find a workaround - alternatively I'll add an example with an up-to-date framework.

Hey - any updates on this? I'm running into the same issue

Has anyone found a fix for this yet?

I don't remember where I got the files from but I put them into my repo so that I can set up the environment anywhere. Feel free to grab the wheel files from there and pip install them.
