Could not find a version that satisfies the requirement torchavision (from versions: none)

This error usually occurs when you are trying to install a package named "torchavision" that is not available or compatible with your current environment.

Make sure you have the correct package name and that it is spelled correctly. Additionally, check if you are using the correct version of Python and if your environment meets the requirements for installing the package.

If "torchavision" is not a widely known package, it might be possible that you meant to install the "torchvision" package instead. In that case, try installing it using the following command:

pip install torchvision

If you are still encountering issues, please provide more details about your environment and the steps you have taken so far.
