I did the exact same but in windows.
pip install "python-doctr[torch]" returns Requirement already satisfied.
But then, from doctr.io import DocumentFile returns ModuleNotFoundError: No module named 'doctr.io'; 'doctr' is not a package
In my case, pip list is showing me the installation python-doctr 0.7.0
Installing it from source had the same result. can u help?
