I had the same symptom: I had installed segment-geospatial and could successfully run "import samgeo" in the QGIS Python console, but I got the same error from the plugin. In my case, this was because I created a Python environment very recently using mamba, which as of 12/19/23 defaults to Python 3.12. I installed QGIS and segment-geospatial in that environment, using "pip install segment-geospatial". Paradoxically, this installs a very old version of segment-geospatial, I believe because very old versions of PyTorch didn't pin the Python version the same way. I.e., new versions of PyTorch are not yet compatible with Python 3.12, so pip had to install a very old version of PyTorch, which resulted in a very old version of segment-geospatial getting installed, so "from samgeo import common" didn't work.

Fixed by doing everything the same way, but in a Python 3.11 environment.
