Is the updated TensorFlow 2.16.1 version conflicting with BERTopic and bertopic.representation import OpenAI?

Hi Maarten,

I've been exploring and enjoying BERTopic and all its super powers for over a month. Thank you for creating something incredible. Strangely though, for the last few days I haven't been able to run the model due to this very challenging and strange error. I noticed that TensorFlow was recently updated and I'm thinking that might be related to the issues, but I'm a complete novice and am not sure what to look for. I hope this is actually a worthwhile flag...

Upon running various versions (with and without each and all pip install bertopic versions) I've been getting stuck on the from bertopic import BERTopic import step:

!pip install --upgrade bertopic
!pip install bertopic
!pip install sentence-transformers
from bertopic import BERTopic
from sentence_transformers import SentenceTransformer

Giving this error:

AttributeError Traceback (most recent call last)

Strangely a day before I started experiencing this error, I had the same issue with OpenAI upon running variations of this:

import io
import pandas as pd
from nltk.util import ngrams
import json

!pip install openai
import openai
from google.colab import userdata
openai.api_key = userdata.get('OpenAI') # add key from https://platform.openai.com/api-keys to Google Colab secrets

from bertopic.representation import MaximalMarginalRelevance, OpenAI

openai_generator = OpenAI(client)
mmr = MaximalMarginalRelevance(diversity=0.3)
representation_models = [mmr, openai_generator]

topic_model = BERTopic(representation_model=representation_models)

With the error:

---------------------------------------------------------------------------

--> 100         raise ModuleNotFoundError(self.msg)

ModuleNotFoundError: In order to use OpenAI you will need to install via; pip install openai

To debug I asked ChatGPT for help. For OpenAI, it told me "_The error message you're encountering indicates a problem with the way the OpenAI class is being imported or instantiated, not necessarily with the openai library installation itself. Given that you've confirmed the openai library is installed, the issue likely lies with how BERTopic is trying to interact with it.

From the BERTopic documentation and the code provided, it seems that the OpenAI class from BERTopic is expected to wrap around the OpenAI functionality. However, the error suggests that when you attempt to instantiate OpenAI(client), it's not recognizing it correctly, potentially due to a version mismatch or an update in the BERTopic library that isn't reflected in the documentation you're using._"

Similarly for the BERTopic errors, ChatGPT told me "The error you're encountering is somewhat unusual and seems to be related to the internals of TensorFlow, particularly after the upgrade to version 2.16.1. The error indicates an issue within TensorFlow's saved model functionality, which might not be directly related to BERTopic but rather to how TensorFlow is being utilized by other libraries you're importing." And recommended running

import tensorflow as tf
print(tf.__version__)

I am running 2.16.1 and restarted the runtime and ran !pip install --upgrade sentence-transformers bertopic before running from bertopic import BERTopic again. No matter what I've tried, I suddenly can't get the model to run.

Thank you again,
Charlotte

Start by reproducing the from bertopic import BERTopic and from bertopic.representation import OpenAI imports in the reported Python environment, then check the TensorFlow version as shown. Compare the installed BERTopic, sentence-transformers, TensorFlow, and OpenAI package versions; done means the documented imports and model setup work without either reported error.
