Hi, this looks like a Python 3.9 compatibility issue to me. The numba JIT compiler that clifford uses does not quite yet support Python 3.9, see https://github.com/numba/numba/issues/6345 , looks like they are planning support for 3.9 sometime early in the new year so probably best to use python 3.8 in the meantime

This appears to work now, under Python 3.9.19 but only with numba 0.58.1, before the removal of generated_jit. Close?
