I am running on google colab, using pytorch version 1.7.0 , torchvision 0.8.1 and cuda 10.1. Same error is coming with cuda 9.2 also.

Based on the stack trace it seems you might be using a custom roi_align method, which is raising this issue. If so, could you check which line of code exactly is raising the error?

I got the same error after upgrading Pytorch. It seems the problem is caused by apex compiled with the old Pytorch. After reinstalling apex from source, the problem is gone.

Hi, I have the same error. Using PyTorch 1.7 on CUDA 11.0 installed thus:

pip install torch==1.7.0+cu110 torchvision==0.8.1+cu110 -f https://download.pytorch.org/whl/torch_stable.html

The error comes from line 138 on this script: https://github.com/MhLiao/DB/blob/master/assets/ops/dcn/functions/deform_conv.py
which calls the CUDA function in the compiled deform_conv_cuda.

I had to make some changes to the .cpp files back when upgrading to PyTorch 1.6, but had no problems after that. This is totally new.

Not sure if apex is being used?
