Drawing a line to the scope of Python packaging

For example, if you conda install a version of scipy, it will pull down a known compatible version of numpy. This may not be the latest version that’s on PyPI, though, which means if you “pip install --upgrade” something that depends on numpy you’ll upgrade it to a version that is no longer compatible with the version of scipy you have installed.

Isn’t that the same with pip? It can also happen (without conda) that pip install --upgrade numpy upgrades numpy to a version that is no longer compatible with the version of scipy you had.
