import _C

I saw that in your ipynb file, you have import _C. May I know what it is? I am ready familiar with it

When you run python setup.py develop, it uses Extension package from PyTorch for compile and future use some utils (NMS, ROI_Align, ROI_Pool, etc.) written on C++. This line on code of setup.py.

All C++ sources you can find in ./lib/csrc/

I am ready familiar with it

May be you need to update some python dependencies from notebook, i used it long time ago.

Thank you for that!

Also, I am trying to replicate your installation: !pip install torch==1.4.0+cu100 torchvision==0.5.0+cu100 -f https://download.pytorch.org/whl/torch_stable.html

But when I try to, it prompts me that the earliest I could get it torch==1.7.1+cu101

Would this still work?

There is no problem with Cuda 10.1

I ran this notebook when PyTorch 1.5.0 was latest release. Previously, version 1.5.0 could work without changes, but I can't say the same about versions 1.5.0+

The PyTorch team sometimes makes breaking changes to their framework. If you decide to use version 1.7.1, then you may have to make changes to the neural network code.

Feel free to pull requests for fixes to support the new version.
