Issue using BERTopic with umap in a Jupyter notebook

June

An issue occurs when passing the umap model to the BERTopic class.

I am trying to duplicate this code:

https://maartengr.github.io/BERTopic/faq.html#why-are-the-results-not-consistent-between-runs

I get this error in my Jupyter Notebook:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-2-2c902ae25352> in <module>
      1 umap_model = UMAP(n_neighbors=15, n_components=5, 
      2                   min_dist=0.0, metric='cosine', random_state=42)
----> 3 topic_model = BERTopic(umap_model=umap_model)

TypeError: __init__() got an unexpected keyword argument 'umap_model'

I am using a custom code env with these packages installed:

• bertopic==0.3.4
• umap-learn==0.5.3

My complete code is this:

import dataiku
from dataiku import pandasutils as pdu
import pandas as pd
from bertopic import BERTopic
from umap import UMAP

umap_model = UMAP(n_neighbors=15, n_components=5, 
                  min_dist=0.0, metric='cosine', random_state=42)
topic_model = BERTopic(umap_model=umap_model)

This code (without the dataiku pkgs) works in an external IDE.

Operating system used: Windows

Shashank

umap_model attribute is added in Bertopic version >=0.10.

I tested the code with bertopic==0.12.0, this should work.

This worked. I did have to update pandas to 1.3 as well in order to use this package.

Thank you!
