I'm afraid I don't know conda at all, but I'm guessing that pip will
not install numpy when it is installed via conda.
So the potential difference is that, pre-wheel, if numpy was not
installed in your conda environment, then pip would build numpy from
source, whereas now you'll get a binary install.
I _think_ that Python's binary API specification
(pip.pep425tags.get_abi_tag()) should prevent pip from installing an
incompatible wheel. Are there any conda experts out there who can
give more detail, or more convincing assurance?
