Plotly: невозможно связаться с локальным процессом orca-сервера, даже если кажется, что процесс сервера запущен

Question

При рендеринге графического изображения в файл следующим образом:

import plotly.graph_objects as go

def produce_graph(graph, data_dir):
    figure = go.Figure()
    [...]
    figure.write_image("output_file.png")

я получаю следующую ошибку:

During handling of the above exception, another exception occurred:

ValueError: 
For some reason plotly.py was unable to communicate with the
local orca server process, even though the server process seems to be running.

Please review the process and connection information below:

orca status
-----------
    state: running
    executable: /usr/local/bin/orca
    version: 1.2.1
    port: 65465
    pid: 90478
    command: ['/usr/local/bin/orca', 'serve', '-p', '65465', '--plotly', '/Users/brunorijsman/cascade-python/env/lib/python3.7/site-packages/plotly/package_data/plotly.min.js', '--graph-only', '--mathjax', 'https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/MathJax.js']

Я также пытался отрисовать файл .png и файл .jpeg, и в этих случаях я получаю точно такую ​​же ошибку.

Визуализация рисунка в браузере работает нормально:

figure.show()

Я уже пытался добавить следующее, но это не имеет значения:

plotly.io.orca.ensure_server()
time.sleep(10)
