The problem

Upon running QuartiCal, the following (non-fatal) message may appear:

The TBB threading layer requires TBB version 2021 update 6 or later i.e., TBB_INTERFACE_VERSION >= 12060. Found TBB_INTERFACE_VERSION = 12050. The TBB threading layer is disabled.

The reason
When installed with pip, numba may fail to find tbb - see numba/numba#7148.

The solution
pip install tbb - this ensures that tbb is installed. Then do export LD_LIBRARY_PATH=/path/to/your/venv/lib.
