"No module found" when HDX Utilities gets ahead of HDX Country

[StuartBertram]

I just did an update and got hdx-python-utilities v4.0.4, but hdx-python-country stayed on 3.9.8. This then leads to the following stack trace when importing any of the hdx-python-country classes:

../../path/to/myfile.py:10: in <module>
    from hdx.location.country import Country
.venv/lib/python3.14/site-packages/hdx/location/country.py:13: in <module>
    from hdx.utilities.typehint import ExceptionUpperBound
E   ModuleNotFoundError: No module named 'hdx.utilities.typehint'

It looks like hdx-python-country requires hdx-python-utilities >=3.9.2, but doesn't put an upper bound on it. That lets the utilities get ahead of the country package, which results in a mismatch between the pre-Python3.10 code and the newer code that targets Python 3.10.

I don't know whether you're likely to release a new 3.x version for anyone not moving to 4.x to fix it there, but if you expect the versioning to stay consistent then it might be worth putting a "and <5.0" condition on the 4.x branch to avoid this happening in the next big version upgrade.

In the mean time, I'll just change my versions and move to hdx-python-country 4.x (or people can manually specify hdx-python-utilities < 4)

Hmm, good point. Generally I'd recommend updating HDX Python Country to the latest version when updating HDX Python Utilities to latest. I've added to the breaking changes about pinning hdx-python-utilities < 4 when using country < 4.

[StuartBertram]

Yeah, I agree. It's just that in this case I just did poetry lock --regenerate and it re-locked the packages at the newest versions that met the requirements. Because of the lack of upper bound on hdx-python-country's dependency on hdx-python-utilities then it pulled in v4 while I still only had a dependency on hdx-python-country of 3.x.

So it wasn't that I actively updated one and got them out of sync. It's that the dependencies as specified allow the dependency management process to resolve the dependencies to incompatible versions, and if your dependency is hdx-python-country (>=3.0;<4.0) then you'll now get hdx-python-utilities v4, even though it isn't compatible.

@StuartBertram I'll add a pin in the next version after 4.1.0 which I released before I read your followup.
