In my case, I uninstalled previous pytorch(torch) following your guide. But, I got “0.3.0.post4” by command “print(torch.version)” even can’t find torch in “pip list”! There is some problem about caching python module in using notebook. Best solution is make new notebook and install lasted pytorch version. Another solution is deleting cache. Click “Restart Runtime” below “Tool” in colab menu. Then you can see message “ModuleNotFoundError: No module named ‘torch’”.
