Kaleido failed to start in docker running windows

[flo453]

Hello everyone,

I have a working plotly dash project that generates png files when I run it in my local environment. I now set up a docker container and generating png does suddenly not work anymore.

Error: "File "C:\venv\lib\site-packages\plotly\basedatatypes.py", line 3821, in write_image return pio.write_image(self, *args, **kwargs) File "C:\venv\lib\site-packages\plotly\io_kaleido.py", line 268, in write_image img_data = to_image( File "C:\venv\lib\site-packages\plotly\io_kaleido.py", line 145, in to_image img_bytes = scope.transform( File "C:\venv\lib\site-packages\kaleido\scopes\plotly.py", line 153, in transform response = self._perform_transform( File "C:\venv\lib\site-packages\kaleido\scopes\base.py", line 293, in _perform_transform self._ensure_kaleido() File "C:\venv\lib\site-packages\kaleido\scopes\base.py", line 198, in _ensure_kaleido raise ValueError(message) ValueError: Failed to start Kaleido subprocess"

Used Docker Enviroment:

• windows servercore mcr from microsoft, "mcr.microsoft.com/windows/servercore:ltsc2019"
• python 3.8.6
• kaleido 0.2.1
• plotly 5.3.1
• dash 2.0.0

Is there a way to solve this ?
