I am getting this error in that code. What should i do to solve this problem?
I ran this in colab.

Hi. It seems that Colab has updated their PyTorch version for the default environment.

You may try to uninstall the existing PyTorch and CUDAToolkit and reinstall the corresponding version (1.7+cu101 in this case) by refering to the PyTorch website: https://pytorch.org/get-started/previous-versions/#v170

Another alternative is to install a newer version of Detectron2 and AdelaiDet that are compatible with the Colab included PyTorch and see whether the models still work.

Hope this will solve the issue.
