pip install sctk
If you encounter dependency clashes, create a fresh python 3.9 virtual environment (e.g. via conda) and install SCTK there. It may also help to update pip:
pip install --upgrade pip
SCTK's documentation is available here, and features a tutorial and API reference for scAutoQC (an automated QC workflow).
