PyTorch no longer supports this GPU because it is too old.

have installed CUDA ToolKit 8.0

I really need support for 2.1 compute capability and version >= 1.0.1, please help!

Consider using a cloud computing service (e.g. Google Colab, Google Cloud or AWS). Colab is free (with some limitations), so you may want to check if that meets your needs first.
