Thanks for the report @1178615156. Could you also describe the hardware that your are running on? For example, the initial aarch64 support was only tested on the raspberry pi (https://github.com/plotly/Kaleido/pull/35).

I'm not very familiar with how Docker works on arm, but if I understand correctly it looks like you are using the standard (intel) version of the python:3.7 image. Do other native compiled packages like numpy, pandas, and matplotlib work fine in this setup? Have you tried using kaleido from the base operating system outside of docker?

@Bibo-Joshi, if you have a moment, could you confirm whether the latest version of kaleido is still working for you in your arm64 setup? Thanks!

Upgraded from 0.0.3.dev5 to 0.0.3.post1 ad it seems to run fine for my use case :)

@Bibo-Joshi Thanks!

the hardware is huawei service

[henry-fung]

Is there any update for this issue?

[bedeberger]

Same issue here, cannot execute Kaleido on a Raspberry Pi 5 - regardless of Kaleido's version. Error is: Segmentation fault

[gvwilson]

Thanks for your interest in Kaleido. We are currently working on an overhaul that might address your issue - we hope to have news in a few weeks and will post an update then. Thanks - @gvwilson
