If you have conflicts then you have to reconcile those at point of initial install - pip deals with that for you. I’ve never had a situation in 15 years of Python packages where there wasn’t a working combination of versions.
These are genuine questions btw. I see these common complaints and wonder how I’ve not ever had issues with it.
1- pip freeze will miss packages not installed by pip (i.e. Conda).
2- It does include all packages, even not used in the project.
3- It just dumps all packages, their dependencies and sub-dependencies. Even without conflicts, if you happen to change a package, then it is very hard to keep track of dependencies and sub-dependencies that need to be removed. At some point, your file will be a hot mess.
4. If you install specific platform package version then this information will not be tracked
2/3- you need to track only the direct dependencies _manually_ but for reprodicible deployments you need fixed versions for all dependencies. The latter is easy to generate _automatically_ (`pip freeze`, pip-tools, pipenv/poetry/etc).
If I want to install something, I pip install and then add the explicit version to the base. I can then freeze the current state to requirements to lock in all the sub dependencies.
It’s a bit manual (though you only need a couple of cli commands) but it’s simple and robust.
But if someone is coming from data science and not dev-ops then no matter how much we say “all you have to do”. The response will be why do I have to do any of this?
3 is solved by the workflow of manually adding requirements and not including dependencies. It may not work for everyone. Something like pipreqs might work for many people.
I do not understand why 4 is such a problem. Can you explain further?
How does it handle the problem?
