deep-learning

Solution 1:^[1]

These error occur because DCNv2 require torch version 1.4.0 so simply I had degraded torch version after that try to build again

!pip install -U torch==1.4 torchvision==0.5 -f https://download.pytorch.org/whl/cu101/torch_stable.html

Thanks?I fixed. Simply I had degraded torch version after that try to build again?
