Python programming part is not working in a question inside an Exam

[Javier Ivan Mendoza Aguilar]

Hi everyone, I'm testing a question with a Python programming part. In this question students should write a piece of code to graph a simple equation. To prepare the question  in the preamble I import matplotlib.pyplot as plt and numpy as np. I insert other code stuff needed for the drawing too. The question works pretty well if it's standalone, but when it's inside an Exam the problem appears. 

Traceback (most recent call last): File "/lib/python3.10/asyncio/futures.py", line 201, in result raise self._exception File "/lib/python3.10/asyncio/tasks.py", line 232, in __step result = coro.send(None) File "/lib/python3.10/site-packages/_pyodide/_base.py", line 506, in eval_code_async await CodeRunner( File "/lib/python3.10/site-packages/_pyodide/_base.py", line 357, in run_async coroutine = eval(self.code, globals, locals) File "", line 1, in

NameError: name 'plt' is not defined

PD:

In the same question other programming part works as expected, both as standalone and in Exam. This is the preamble for this question

import numpy as np
from scipy.optimize import fsolve

Any help would be appreciated.
Thank you in advance

Hi Christian, this is the link to the question:

Load line

After many tests, I've been noticing an intermitent problem, sometimes the question works as expected within an Exam.

I wonder if this could be due to a network problem. The next time this happens, could you open the browser's developer tool (press the key F12) and give me a copy of what's shown in the Console tab?
