remove `Loading [MathJax]/extensions/MathMenu.js` message

I am working with plotly but the output image show the watermark:
My code:

df = pd.read_json(os.path.join(path_rq12, 'macro-topics.json'))

categories = []
frequency_p = []
frequency_k = [] 

for index, group in df.groupby('Challenge_topic_macro'):
    categories.append(macro_topic_indexing[index])
    frequency_p.append(len(group[group['Challenge_type'] == 'problem']))
    frequency_k.append(len(group[group['Challenge_type'] == 'knowledge']))
    
# Create a stacked bar chart
fig = go.Figure(data=[
    go.Bar(name='Problem', x=categories, y=frequency_p, text=frequency_p, textposition='outside'),
    go.Bar(name='Knowledge', x=categories, y=frequency_k, text=frequency_k, textposition='outside')
])

# Change the bar mode
fig.update_layout(
    barmode='group',
    xaxis_title="Macro-topic Name",
    yaxis_title="Post Number",
    xaxis=dict(title_font=dict(size=18)), 
    yaxis=dict(title_font=dict(size=18)),
)
fig.show()
fig.write_image(os.path.join(path_rq12, 'Macro-topics frequency histogram.pdf'))

My output image:

OS: Ubuntu 20.04
Python: 3.10.9
Plotly: 5.16.1

Similar to #3469, any idea? @nicolaskruchten @chriddyp @jonmmease

Do you have any updates on this?

Sorry but we don't have updates on this issue as of yet.

I see a similar issue when exporting to pdf. Nearly 2 years ago, the following worked for me:

  # -------------------------- first time -------------------------- #
  import plotly.express as px 
  import time 
  file_Name="some_Figure.pdf"
  fig_Throw_Away = px.scatter(x=[0, 1, 2, 3, 4], y=[0, 1, 4, 9, 16])
  fig_Throw_Away.write_image(file_Name, format="pdf")
  time.sleep(0.1)
  
  # delete the dummy file again
  path_Cwd = Path.cwd()
  file_2_Del = path_Cwd/file_NamendError exceptions will be ignored (same behavior as the POSIX rm -f command).
  file_2_Del.unlink(missing_ok = True)
  
  # ------------------------ end first time ------------------------ #ndError exceptions will be ignored (same behavior as the POSIX rm -f command).
  file_2_Del.unlink(missing_ok = True)
  
  # ------------------------ end first time ------------------------ #
  
  # now run your actual code to generate the plot that you like

The idea is to create a dummy plot, wait a bit and after the waiting you can plot your actual figure that you like. Again, no guarantees, but it worked for me some time ago

plotly.py v7.0.0 now bundles MathJax v3 rather than v2 (see #5684), and the message bar is no longer included in v3, so this is resolved.

Note that Kaleido v1.4.0 or greater must be used for generating images, since that is the first version which uses MathJax v3 by default.
