See the error we encountered in conda-forge for v7.2.0 when trying to switch from GitHub tarball to PyPI’s: conda-forge/cupy-feedstock#37 (comment). There we did specify CUB_PATH to make CUB visible to pip. The reason for the error is that both cupy/cuda/cub.cpp and cupy/cuda/cupy_cub.cu are absent in the PyPI source.
