Besides the horrendous formatting, some stuff in this article seem incorrect or irrelevant. Like, is this even possible?
> A single Anaconda distribution may have multiple NumPy versions installed at the same time, although only one will be available to the Python process (note that this means that sub-processes created in this Python process won’t necessarily have the same version of NumPy!).
I’m pretty sure there’s not, but maybe there is some insane way to cause subprocesses to do this. Besides that, under the authors definition, different Python virtualenvs also install multiple copies of libraries in the same way conda does.
The comments about Jupyter also seem very confused. It’s hard to make heads or tails of exactly what the author is saying. There might be some misunderstandings of how Jupyter kernels select environments.
> Final warning: no matter how ridiculous this is: the current directory in Python is added to the module lookup path, and it precedes every other lookup location. If, accidentally, you placed a numpy.py in the current directory of your Python process – that is going to be the numpy module you import.

This has nothing to do with conda.
