I got the following error while I tried executing the repo:

Kindly help at the earliest possible.

Have you run the following command?

$ pip3 install -r requirements.txt

[luharinos]

Yes, I created a python3.6 virtual environment, installed requirements.txt via pip, which showed an error:

tensorflow 1.11.0 has requirement setuptools<=39.1.0, but you'll have setuptools 40.4.3 which is
incompatible.

Later, I installed tensorflow separately using;

$ pip install tensorflow

which uninstalled setuptools-40.4.3 and installed setuptools-39.1.0

When I tried checking the version of the tensorflow using:

$ python -c 'import tensorflow as tf; print(tf.__version__)'

it again shows the above mentioned error.

I think the problem is related to protobuf. I found the same issue here.

FYI, you can try reverting protobuf to version 3.6.0:

Running Windows 7, python 3.6.0 (Anaconda 4.3.0). I can confirm this same error message with protobuf 3.6.1 (protobuf 3.6.1 installed as part of an upgrade to tensorflow-gpu 1.10.0, and the error prevented tensorflow from successfully importing).
I can also confirm that reverting to protobuf 3.6.0 allowed me to successfully import tensorflow (for those encountering the error this way and looking for a temporary solution).

[luharinos]

Yes, the earlier version of protobuf was 3.6.1, which I downgraded to 3.6.0, using:

$ pip uninstall protobuf
$ pip install protobuf==3.6.0

The game, now, works smooth and fine.

Thanks for your quick and kind help!
