ValueError: Failed to start Kaleido subprocess

[brunotjuliani]

I'm having and issue with the fig.write_image() function. The code was functioning well, but now the following message appears:

File "/opt/anaconda3/lib/python3.8/site-packages/plotly/basedatatypes.py", line 3806, in write_image return pio.write_image(self, *args, **kwargs) File "/opt/anaconda3/lib/python3.8/site-packages/plotly/io/_kaleido.py", line 245, in write_image img_data = to_image( File "/opt/anaconda3/lib/python3.8/site-packages/plotly/io/_kaleido.py", line 131, in to_image img_bytes = scope.transform( File "/opt/anaconda3/lib/python3.8/site-packages/kaleido/scopes/plotly.py", line 153, in transform response = self._perform_transform( File "/opt/anaconda3/lib/python3.8/site-packages/kaleido/scopes/base.py", line 293, in _perform_transform self._ensure_kaleido() File "/opt/anaconda3/lib/python3.8/site-packages/kaleido/scopes/base.py", line 198, in _ensure_kaleido raise ValueError(message) ValueError: Failed to start Kaleido subprocess.

Hi @brunotjuliani,

thanks for the report. This part of the error messages [0510/172927.836500:ERROR:platform_shared_memory_region_posix.cc(253)] Unable to access(W_OK|X_OK) /tmp: Read-only file system (30).

Does it make sense that your process wouldn't have write access to the /tmp directory? If that's the case (and you can't change it), you could try removing the --disable-dev-shm-usage chromium flag and see if that makes a difference. Here's the general docs on customizing chromium flags (https://github.com/plotly/Kaleido/wiki/Customizing-Chromium-Flags). In particular, try doing this before the write_image call.

import plotly.io as pio
pio.kaleido.scope.chromium_args = tuple([arg for arg in pio.kaleido.scope.chromium_args if arg != "--disable-dev-shm-usage"])

This worked just fine. Thanks for the response.
