### Problem to solve Python developers often use a combination of private, in-house built packages and packages that are publically available in the public [PyPI registry](https://pypi.org/). However, we do not currently help users with pulling packages from this popular, remote repository. ### Intended users * [Sasha (Software Developer)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#sasha-software-developer) * [Devon (DevOps Engineer)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#devon-devops-engineer) ### Proposal When a user tries to download a PyPI package using their Project/Group/Instance-level endpoint and the package is NOT found, forward the request to pypi.org and, if possible, download the package. ### Further details This feature is part of our effort to deliver a virtual registry for the PyPI repository that will proxy and cache requests for packages outside of GitLab.
