@Tawishi thanks for the PR, however here we have to replace CustomPeriodicEvent by the new API as I described it here : #1247 (comment)

Please, update the PR according to that and if you could rerun it inside Colab it would be awesome.
Let me know if you have any questions.

@vfdev-5 I am facing this error and a warning while installations. Please help.

I ran the second command and got this in the terminal window.

1. git clone https://github.com/NVIDIA/apex && cd apex
2. pip install --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" .

It seems to a Python3.3 error as stated in this post. How to go about this?

@Tawishi I think it could not identify the location of cuda library. And also there is a message saying that there is no GPUs on the system... May I ask you what would you like to do ?

If you would like to test your modifications, I'd suggest you to use Colab where you can choose a system with GPU and cuda properly installed.

[Tawishi]

I will try out Colab and let you know if I face any problem.
