ModuleNotFoundError: No module named 'tensorflow.contrib'

What an interesting project, thanks for this. I've tried to run the demo to train an agent, but got this error:

~/freqtrade$ python deep_rl.py

Is it related to this?

`tensorflow.contrib is being removed in version 2.0``

If so, I could not fix it with this: https://github.com/deetungsten/stable-baselines

Any other ideas? Should I just revert to Python 3.7 and Tensorflow <2.x ?

python3 -c 'import tensorflow as tf; print(tf.__version__)'
I tensorflow/stream_executor/platform/default/dso_loader.cc:48] Successfully opened dynamic library libcudart.so.10.1
2.3.1

So I guess for now Tensorflow <2.0 and Python =<3.7 is required.

Yes, stable baselines only supports tf 1.X for now, there are some tf 2 forks, but I'm not sure if there is something far enough yet.

The stable-baselines library currently supports Tensorflow versions from 1.8.0 to 1.15.0, and does not work on Tensorflow versions 2.0.0 and above. Source

Use this command to install tensorflow 1.15. pip install --upgrade tensorflow==1.15.0

Stable baseline now supports TF2: https://github.com/DLR-RM/stable-baselines3

@tinof Stable baseline now supports TF2: https://github.com/DLR-RM/stable-baselines3 I am afraid that is a PyTorch version instead of TF2. And last time I checked. That version is in early stage, so it lack of several major features like multi processing.

Yes, you are right. I was able to run freqtrade gym with stable-baselines3 after some slight modification. Btw, awesome project. To be honest, I am still kinda new in openai, gym, stable_baselines, ray, etc.

As I am still kinda new in reinforcement learning, I would need some insight/advices from the expert. Can you enlighten me on this portion of code in freqtradegym.py?

Why self._reward being set to zero at the beginning of the function and why it has to be reset to zero when self._reward > 1.5?

By the way, I would like to implement sortino / omega as rewarding scheme instead of profit only rewarding scheme. Anyone can kindly highlight which part of the code should I dive into? It is observation( ) function in freqtradegym.py?

Ah, I forgot why I did that. Maybe just trying something out. This is an experimental project. Feel free to remove it and do more experiments.

Man, how did you do that? I'm trying to run with stable-baselines3, but i've some problems with libraries, like ACER, maybe you can share your code for gym, strategy and deep_rl?
