Failed to load module "appmenu-gtk-module"

I installed orca via

conda install -c plotly plotly-orca

Running it, I get the message

$ orca
Gtk-Message: 20:48:12.453: Failed to load module "appmenu-gtk-module"
Segmentation fault

On my system (Debian 10.2) there is no package appmenu-gtk-module. Instead I tried installing appmenu-gtk2-module and appmenu-gtk-module-common, with no success.

chromium is installed, since it is my default browser.

How do I get orca to run? I need it for PDF export from plotly.

Can you please try installing appmenu-gtk3-module or appmenu-gtk2-module and report here whether it fixed the problem or not?

PS: Why does a command-line program that has no UI and is meant to run invisibly in the background have so many dependencies on desktop libraries and need a running X server?

@allefeld the reason is that plotly.js was designed for the web first and therefore relies on having a functional browser (a DOM, a WebGL renderer, etc.) to build figures. At the moment, I don’t think that running plotly.js outside the browser would be trivial (at least not if we want to support all the different trace types). Therefore, we have to ship a browser, a display server, and all the other dependencies. It is not ideal but that’s what it is.

If you have Docker on your Linux machine, I personally recommend running Orca in a Docker container docker run -p 9091:9091 quay.io/plotly/orca which is 1) a one-liner and 2) will always work reproducibly.

Great, thanks a lot!
