Issue with BERTopic Installation - ModuleNotFoundError for importlib-metadata

Nobody has claimed this yet.

Hello Support Team,

I am encountering an issue with the BERTopic package in Python, specifically a ModuleNotFoundError related to the importlib-metadata module. Despite BERTopic's documentation stating compatibility with Python 3.7

I have looked into this but couldn't find the solution: -

As while importing BERTopic, it needs umap:
https://github.com/MaartenGr/BERTopic/blob/master/bertopic/_bertopic.py#L38

which also imports importlib.metadata:
https://github.com/lmcinnes/umap/blob/master/umap/__init__.py#L36

The error clearly says the package is missing but it is being installed automatically:
importlib-metadata==6.7.0
importlib-resources==5.12.0
​
We tried different package versions but this didn't help.

my current requirements file looks like this: -

**bertopic[spacy]==0.15.0
plotly
seaborn
matplotlib
wordcloud
urllib3<2.0,>=1.21.1
nbformat>=4.2.0
enchant
ipywidgets
protobuf
openai==0.28.1
spacy==3.7.2
pydantic==1.10.13**

The code environment does build up but when we try to load the libraries we get the error
``

I would appreciate any guidance or assistance you can provide in resolving this issue. If any additional information is required, please let me know.
Thank you for your time and support.

Reproduce the traceback in a Python 3.7 environment using the requirements shown. Start with bertopic/_bertopic.py at the UMAP import and compare it with umap/__init__.py at the importlib.metadata line. Done should identify whether the documented environment is supported and provide a verified compatibility fix or clear installation guidance.
