Discussion:
It looks like this package has been removed from PyPI, or at least renamed. Do you know of any other package that depends on it? What did you need it for?
In the instructions for building Tensorflow from scratch it is listed as a dependency. I'm currently trying to install it without py-dev, which seems to be working so far. Otherwise I have no idea what it is used for.
Ah. Let me see if I can dig around the TensorFlow instructions. I'm sure a lot of other people have run into this problem.
In the installation instructions, it shows them installing `python-dev` with apt-get. But `python-dev` isn't the `dev` Python library, it's the Python development headers: https://stackoverflow.com/questions/31002091/what-is-python-dev-package-used-for
P.S. How easy was it to install TensorFlow by hand? We've been wanting to add a Spack package forever but the build system is impossible to deal with and requires internet access and downloads all of its own dependencies.
