I'm using two python packages that have the same name.
Is there a canonical or pythonic way to handle installing two packages with conflicting names? So far, I've only occasionally needed one of the packages during development/building, so I've been using a separate virtualenv to deal with the conflict, but it makes the build step more complex and I wonder if there isn't a better way to handle it.

The easiest and most sane way to do it is to refactor you project and change the name of the file. There are probably some way strange way around this, but I would hardly consider that worth it, as it would most likely complicate your code, and make it prone to errors.
By default, Python paths are relative to the main script that is being executed. On Python 2.7 and older, imports are also relative to the module doing the importing. This means if you get weird import errors, check for name clashes. The higher-level lesson here is that absolute imports are easier to understand.
Unfortunately, pip makes no attempt to resolve dependency conflicts. For example, if you install two packages, package A may require a different version of a dependency than package B requires.
Python packages and modules can not use hyphens, only underscores. This section of PEP-8 gives us guidance: Package and Module Names: Modules should have short, all-lowercase names. Underscores can be used in the module name if it improves readability.
You could use the --target option for pip and install to an alternate location:
pip install --target=/tmp/test/lib/python3.6/site-packages/alt_alembic alembic
Then when you import in python, do the first as usual and for the alt do an import from that namespace like this:
import alembic # alembic.io version
from alt_alembic import alembic as alt_alembic # pip version
Then when you're making calls to that one you can call alt_alembic.function() and to the one that isn't in PyPi, alembic.function() My target path has /tmp/test as I was using a virtual env. You would need to replace that path with the correct one for your python installation.
