Freeing up space on PyPI for nightly wheels
We use Azure and GitHub for uploading nightly Python wheels to PyPI on a schedule. As of time of writing, there are 20 NEURON wheels being uploaded each time the scheduled CI runs, and each wheel is roughly 20 MB in size, so ~ 400 MB worth of content is uploaded to PyPI on every run.
Unfortunately, PyPI has limited resources, and each project has, as of time of writing, 10 GB of storage for their entire project, so assuming regular NEURON repo activity, we can expect an upload to happen daily, which means that, without deleting older versions of the nightly wheels, we would run out of space in less than a month.
Here I will explain how to check available storage, as well as how to delete older versions of nightly wheels so newer ones can be uploaded without running out of space on PyPI.
The available storage should be displayed on the NEURON nightly PyPI settings page (https://pypi.org/manage/project/neuron-nightly/settings/):
Go to the management page of NEURON nightly on PyPI (https://pypi.org/manage/project/neuron-nightly/releases/), which should look like this:
Click on "Options" for one of the versions, and then on "Delete", which will open up a screen like this:
Input the version in the box and click on "Delete release".
