Colab compatibility improvements

[AlphaGit]

Hi! I just added these fixes that improve on the Colab compatibility experience.

• Ensure Google Colab GPU Compatibility
  • Added parameters to compile for all available GPU models in Google Colaboratory.
  • Moved the instructions to a common file used by all setup files
  • Adapted Colab file, removing outdated error indicators
• Suppressing compiler warnings
• Updated documentation
  • Updated documentation inside and outside of Colab file.
  • Removed references to any shared Colab file, to avoid outdated versions out there. The one in the master branch of this repo should be the canonical one.
  • Added versioning to the file itself, so we can easily tell when someone is using an old version of the file.
  • Added markdown input for configuration

Hi, thank you for your commits, but I meet an error(error in correlation_forward_cuda_kernel: no kernel image is available for execution on the device) when I use Tesla V100 with compute capability 7.0.
I change the arch gen-code in the compiler_args.py. However, it seems that it doesn't work.
Thanks in advance!

Hi there! It seems like you're on the right path. Did you try adding both the arch and code to 70 compatibility?

Also, I know that this error can also occur on cases where the CUDA drivers are not quite supported -- I'm not entirely sure how to verify that's the case. Around the internet people just keep trying different versions of pytorch, cuda and nvidia drivers until they find a combination that works. What we did is fixed those in Colab to a known working version.

Hi,thank you for your reply!

Yes,I use both the arch and code. First, I fork this repository from your Github. Then I add the
'-gencode', 'arch=compute_70,code=[sm_70,compute_70]' in the compiler_args.py. At last, I modify the git source in the colab file from my github. But it seems that it is not a useful way.

I tried it with a V100 on my Colab Pro account, and I had the same error. When I used a non-Colab Pro account, I got a T4 GPU and it worked as expected.
