requirements files for notebook

[den-run-ai]

Is there any way to generate requirements files for notebook based on imported/used modules and packages?

[takluyver]

We don't provide anything like that, but you could write a tool to do it if you want. The fiddly bit would be matching up import names to PyPI names (which are often the same, but they don't have to be).

Here are 2 packages that can do this for Python code:

https://github.com/bndr/pipreqs

I was setting up my dev environment and there are a number of packages not listed in the requirements file, but necessary to develop ipython. This includes requests and nose - should we add a requirements-tests.txt file?

@jamesfe we only used requirements.txt for unreleased dependencies. To install IPython and its testing dependencies use pip install "ipython[test]"

[takluyver]

@minrk can we now remove requirements.txt again? The only thing left in it is traitlets, and I don't think IPython requires an unreleased version of traitlets.

@takluyver yup, #9132.

Also closing here, as we have no plans to implement requirements inside the notebook, and even if we did this is no longer the repo for it.

Thanks!
