datamap visulisation does not work.

[Hansyvea]

other visualisation works except for this. It suggests BERTopic does not have this method.

@Hansyvea Could you provide your error and sample code?
Your #1955 does not provide details either.

PS: I had a similar error on Colab last week.
I presume you might be referring to this error or similar
# "Data map plotting is unavailable unless datamapplot is installed."
# datamapplot not installed

What works for me: Ensure you install and load datamapplot

## Install DataMapPlots: Below for Colab or if working inline within Notebook
!pip install datamapplot

## load library
    import datamapplot

You should be able to execute
topic_model.visualize_document_datamap(docs, reduced_embeddings=reduced_embeddings)
## where reduced_embedding is already derived from your umap fit_transformed.

Should BERTopic datamap not work, you can attempt working with datamap directly.
In my case, I called create_plot directly:
PS: I also had a go at datamapplot.create_interactive_plot() with success.

datamapplot.create_plot(
    reduced_embeddings05,
    docs_info.Name,
...
...)

## where docs_info.Name or ocs_info['Name'] comes from topic_model_.get_document_info

Also, make sure that you install BERTopic v0.16.1 (or higher when it releases) since it was supported first in v0.16.1. If BERTopic suggests that it does not have this function, then it is either what was previously stated or simply install the latest version.

I also have issues getting datamapplot to work. Here is my code:

import datamapplot
print(bertopic.__version__)
0.16.1

topic_model.visualize_document_datamap(docs, embeddings=embeddings, title='', width=1200, height=1200,)

Error output:

@emilbakke Assuming datamapplot was correctly installed, it might be that you need to restart the notebook and try again. Not sure, but it might be that the try/except clause of the datamapplot import was already finished before installing datamapplot but that's a guess since I don't know the exact process.

You are absolutely correct, solved it. The good old reboot. Thanks!
