If you would like to use the Detectron2 models for layout detection, you might need to run the following command:

pip install torch&& pip installlayoutparser[detectron2]

pip install torch&& pip install"detectron2@git+https://github.com/facebookresearch/detectron2.git@v0.5#egg=detectron2"

This might take some time as the command will*compile* the library. If you also want to install a Detectron2 version
