Conda-forge now recommends adding pip check in the recipe. The pointpats package on the conda-forge channel fails pip check with an error pointpats 2.2.0 requires opencv-contrib-python, which is not installed. This is causing issues for all downstream packages that might be submitted to the conda-forge channel in the future. It appears that opencv-contrib-python in the setup.py, but it is not available on the conda-forge channel.
