Troubleshooting

ModuleNotFoundError

Check you have the right environment active:

pip list | grep semantica
pip install --upgrade semantica

Installation fails with dependency errors

pip install --upgrade pip
pip install build wheel
pip install semantica --no-deps   # install without optional deps first

GPU dependencies fail

Install CPU-only first, then add GPU support:

pip install semantica
pip install semantica[gpu]

Permission denied

pip install --user semantica      # or use a virtual environment

Windows [all] install fails

This was fixed in v0.5.0. Upgrade to the latest release:

pip install --upgrade semantica

Windows PyTorch DLL errors

Install the Microsoft Visual C++ Redistributable. This is a Windows system dependency, not a Semantica bug.
