Numpy not loading in Fennec on LineageOS 17.1

[jondo]

Input

plot(x=cos(t), y=sin(t))

How can it be better?

It should yield a plot instead of:

plot([ p1 = (cos(t), sin(t))
])
There was an error in Gamma. For reference the last five traceback entries are: Traceback (most recent call last):

For some reason (maybe network) numpy isn't loaded in your case. Could you refresh to see if it goes normal (and optionally use F12 to check Network 4XX or 5XX)? I can reproduce it when I change numpy to a wrong name here:

sympy_beta/public/worker.js

Line 13 in c47b83a

await self.pyodide.loadPackage(["micropip", "docutils", "numpy", "sympy"])

Anyway I should provide a notification to show something is wrong.

It repeatedly fails with Fennec F-Droid 96.3.0 on my LineageOS 17.1 phone - both with mobile data and with WLAN, but it works with that phone's default web browser (Chromium 89).

For my tests, I have deactivated my Fennec add-ons.

It also works on another phone (Android 12) with the same Fennec F-Droid version in the same WLAN.
So the problem might not be easily reproducable - which can also be seen as good, I guess.

I tried Fennec F-Droid 96.3.0 on my HarmonyOS 2.0.0 (Android 10) and couldn't reproduce it either. I'll leave this issue open until a newer version of LineageOS and Fennec combination is confirmed to work.
