No module named 'torchvision.ops'

This error message usually occurs when you try to import a module that is not installed in your system or with a different version. In this case, it seems that the module 'torchvision.ops' cannot be found.

To fix this issue, you can try the following steps:

1. Check if torchvision is installed in your system by running the command: `pip list | grep torchvision`. If it is not installed, install it by running `pip install torchvision`.
2. If you have installed torchvision, check if it is the latest version by running `pip show torchvision`. If it is not the latest version, upgrade it by running `pip install --upgrade torchvision`.
3. If the above steps do not work, you can try uninstalling and reinstalling torchvision by running `pip uninstall torchvision` and then `pip install torchvision`.
4. If none of the above steps work, you can try installing the specific version of torchvision that you need by running `pip install torchvision==<version_number>`.

After installing or upgrading torchvision, try importing the module again to see if the error is resolved.
