[英]Plotly: unable to communicate with the local orca server process, even though the server process seems to be running
當我將繪圖圖形渲染到文件時,如下所示:
import plotly.graph_objects as go
def produce_graph(graph, data_dir):
figure = go.Figure()
[...]
figure.write_image("output_file.png")
我收到以下錯誤:

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']
我還嘗試渲染到 .png 文件和 .jpeg 文件,在這些情況下我也得到完全相同的錯誤。
將圖形渲染到瀏覽器可以正常工作:
figure.show()
我已經嘗試添加以下內容,但沒有任何區別:
plotly.io.orca.ensure_server()
time.sleep(10)
作為這個問題
你應該設置超時禁用
# Disable the orca response timeout.
import plotly.io._orca
import retrying
unwrapped = plotly.io._orca.request_image_with_retrying.__wrapped__
wrapped = retrying.retry(wait_random_min=1000)(unwrapped)
plotly.io._orca.request_image_with_retrying = wrapped
