Did you rename them manually after the fact, or… ?
I think this comes from one of the cleanup targets in the Makefile trying to remove contents of a build/ subdirectory that isn’t there. Presumably benign.
It’s better to use code blocks for terminal output, but this is still readable enough.
A DeprecationWarning is just a warning, and it comes from Python. It’s warning about standard library functionality that will be removed. Pip still provides this functionality for backwards compatibility, but whatever you’re trying to do is using it, and will eventually have to update it.
The problem is specific to certain "[something]"s that you’re trying to install; it definitely won’t affect everything. Saying any more will depend on the details of the “[something]” in question.
When you installed Tensorflow, did Pip tell you that it was installing from a wheel (some .whl file), or from source (.tar.gz)? If it was from source then there are a lot of things that can go wrong and we’ll probably need a lot more detail to hope to solve the problem. You might be better off with a Tensorflow-specific forum.
