Wordcloud Plots not Displaying

My generate_topic_wordcloud() works stand-alone but not in the function: display_similar_topics().

I tried plt.tight_layout(), but that didn't help either.

There are also problems with: display_topics(), display_keywords(). display_similar_words() works properly.

Here's my jupyter lab packages:

% python -c "import sys; print('\n',sys.version); import ipympl; print('ipympl version:', ipympl.__version__)" && jupyter --version && jupyter nbextension list && jupyter labextension list

Any suggestions?

Recently I have noticed it is necessary to plt.show() for wordclouds to display. This will be fixed in the next version.

@ddangelov I think it will be helpful to return a fig object for later use. Also it may be nice to have a fontpath option since we need it to display other languages(like chinese or japanese etc.) I have an example below.

@dbl001 I had a similar problem and I wrote a wrap method to use it in a streamlit app https://github.com/lightondust/top2vec-apps

the method(just a little change from https://github.com/ddangelov/Top2Vec/blob/master/top2vec/Top2Vec.py#L2657-L2704)

    def wordcloud(self, word_score_dict, background_color="black"):
        fig = plt.figure(figsize=(16, 4),
                         dpi=200)
        plt.axis("off")
        additional_input = {}
        if self.font_path:
            additional_input['font_path'] = self.font_path
        plt.imshow(
            WordCloud(width=1600,
                      height=400,
                      background_color=background_color, **additional_input).generate_from_frequencies(word_score_dict))
        return fig

when use

            fig = self.model.wordcloud(word_score_dict)
            st.pyplot(fig)
