@Hansyvea 你能提供你的错误和示例代码吗？
你的 #1955 也没有任何细节。

PS:上周我在Colab上遇到了类似的错误。
我猜你可能指的是这个错误或者类似的
# "Data map plotting is unavailable unless datamapplot is installed."
# datamapplot not installed
对我有效的方法是：确保安装并加载datamapplot

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

## load library
    import datamapplot

你应该可以执行
topic_model.visualize_document_datamap(docs, reduced_embeddings=reduced_embeddings)
## where reduced_embedding is already derived from your umap fit_transformed.
如果BERTopic datamap不起作用，你可以尝试直接使用datamap。
就我的情况而言，我直接调用了 create_plot :
PS:我还尝试了 datamapplot.create_interactive_plot() ,成功了。

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

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

请确保您安装了BERTopic v0.16.1(或发布时更高版本),因为它首先在v0.16.1中得到支持。如果BERTopic建议它没有这个功能，那么要么是之前提到的情况，要么就是安装最新版本。

我也遇到了datamapplot无法正常工作的问题。以下是我的代码：

import datamapplot
print(bertopic.__version__)
0.16.1

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

错误输出：

假设 datamapplot 已经正确安装，您可能需要重启笔记本并再次尝试。不确定，但可能是在安装 datamapplot 之前，datamapplot 的 try/except 子句就已经完成了，但这只是我的猜测，因为我不了解确切的过程。

您完全正确，已解决问题。老式的重启。谢谢！
