ImportError: cannot import name 'GeometryCollection' from 'shapely' (/opt/conda/lib/python3.10/site-packages/shapely/__init__.py)

If I install roboflow with pip first, I encounter this situation.

Hey @atutuncuogluu. Are you sure your shapely version is shapely>=1.8.0?

[atutuncuogluu]

When I installed some libraries first, I was getting an error because pip made a version correction. When I changed the order of installing the libraries, my problem was solved.

Hey @atutuncuogluu. Are you sure your shapely version is shapely>=1.8.0?

Hi, I also encountered this error using shapely 1.8.2. Shapely 1.8.2 does not import GeometryCollection in the init.py file here: https://github.com/shapely/shapely/blob/1.8.2/shapely/__init__.py

But shapely 2.0 does: https://github.com/shapely/shapely/blob/2.0.0/shapely/__init__.py

So after updating to 2.0, it's fine for me. But you guys should fix the requirements.txt.
