This package installs and then cannot be imported.

>>> import libcloudspawner.spawner
ModuleNotFoundError: No module named 'async_generator'

and once that is dealt with, again: ModuleNotFoundError: No module named 'requests'.

Comparing every third-party import in the package against pyproject.toml:

imported	jinja2, jupyterhub, libcloud, requests, tornado, traitlets
declared	jinja2, jupyterhub, apache-libcloud
missing	requests, tornado, traitlets

tornado and traitlets happen to be installed today because jupyterhub pulls them in, so only requests breaks visibly — but the code imports all three directly, and a transitive that a dependency later drops is a break waiting for someone else's release.

async_generator is deleted rather than declared. It is a compatibility shim for Python 3.5; this project requires ≥3.7, where async def + yield is the language:

@async_generator
async def progress(self):
    while True:
        await yield_(self.nodemanager.spawner_state_event)

becomes a plain async generator. Declaring a shim as a dependency to keep a 2019 workaround alive would have been the wrong repair.

Also the first CI lane this repository has ever had. The only workflow was python-publish.yml, which releases and does not run on a pull request — so nothing checked the four dependency pull requests open here, and none of them could have caught the missing imports either.

There are no tests in the tree, so the lane does not pretend to run any. It proves install, import, packaging, and one behaviour: that LibcloudSpawner.progress is a real async generator, the contract JupyterHub calls it under. That is a behaviour check rather than a grep because a plain async def that never yields would still import cleanly while silently no longer being a generator.

Verified in a fresh virtualenv outside the source tree: pip install -e ., import, the async-generator assertion and python -m build all pass on Python 3.14. actionlint clean.
