connect4 failed to start due to module 'tensorflow' has no attribute 'layers'

[meyrow]

Hello,
I tried to run the default main.py with Othello game. I ran the default main successfully 12 hours.
In order to create some statistics maybe the log should also write to an excell file. How to plot statistics?
I would like to learn and maybe add on the connect4 implementation.
I followed the instruction in README.md. There are no syntax issues after modifing the main.py and pit.py
But at runtime there is an error.
failed to start due to module 'tensorflow' has no attribute 'layers'

Try running pip install tensorflow or pip3 install tensorflow, depending on which version of python your system defaults to.

What OS are you running?

I use PyCharm 2021.1 on windows 10
both commands in your reply run fine and has be installed.
The python interpreter is 3.8.8 and Tensorflow is 2.3.0
A question: in order to run connect4, do i need to downgrade the tensorflow to use version 1 instead of v2 ?

What error do you get now after installing tensorflow?

EDIT:
Just checked the API reference and it does look like you need to downgrade to tensorflow 1.15.
