Failed to build pomegranate

[Har-vit]

In discrete_node.py you import "DiscreteDistribution" and "ConditionalProbabilityTable" from pomegranate. But last pomegranate version has not these. Maybe it's a reason for my failure: "Failed to build pomegranate" during install your library. What do you think?

[Har-vit]

Additional info about my failure:

"Python recognizes 'pomegranate.distributions' as an importable package[^1],
but it is absent from setuptools' packages configuration.

This leads to an ambiguous overall configuration. If you want to distribute this
package, please make sure that 'pomegranate.distributions' is explicitly added
to the packages configuration field.

Alternatively, you can also rely on setuptools' discovery methods
(for example by using find_namespace_packages(...)/find_namespace:
instead of find_packages(...)/find:)."

What do I need to do?

Hello @Har-vit
Could you provide your traceback?

If the error occurs during library installation, it could be a version conflict. Have you tried to install bamt into venv?

Notes: we don't use setuptools, we use poetry, so packages to install are defined by toml file, section [tool.poetry.dependencies].

If it turns out, that feedback from pip will be uninformative:
Could you try to install pomegranate (0.14.8) manually? If an error appears again, provide traceback as well, please.

[Har-vit]

Sorry, I have no traceback. But I managed to install into venv this setup: python==3.9 and bamt==1.1.40

After a while we have faced the same issue.
In fact, full traceback has 2 errors and 2 corresponding reccomendations.

The first one related to pomegranate.distribuiton. It states:
"Python recognizes 'pomegranate.distributions' as an importable package[^1],
but it is absent from setuptools' packages configuration.

This leads to an ambiguous overall configuration. If you want to distribute this
package, please make sure that 'pomegranate.distributions' is explicitly added
to the packages configuration field.

Alternatively, you can also rely on setuptools' discovery methods
(for example by using find_namespace_packages(...)/find_namespace:
instead of find_packages(...)/find:)."

Actually we have found in pomegranate's whl:
packages=['pomegranate', 'pomegranate/distributions'].
However, this error is not a part of actuall issue.

The second one is about C++ installation. It states:

copying pomegranate\distributions\distributions.pyx -> build\lib.win-amd64-cpython-310\pomegranate\distributions
running build_ext
building 'pomegranate.BayesClassifier' extension
error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ BuildTools":https://visualstudio.microsoft.com/visual-cpp-build-tools/

After installation the issue was solved.

Note that we find the error from issues:
https://stackoverflow.com/questions/70377207/can-not-install-scikit-learn, which apparently has the same origin.
