ImportError: cannot import name ‘mtext’ from ‘matplotlib.axes’

[Hkgayau]

I was trying to follow the "getting-started" tutorial and encounter this error.

from commonroad.common.file_reader import CommonRoadFileReader
from commonroad.visualization.mp_renderer import MPRenderer



file_path = "location4.xml"

scenario, planning_problem_set = CommonRoadFileReader(file_path).open()

# plot the scenario
rnd = MPRenderer(figsize=(25, 10))
scenario.draw(rnd)
rnd.render(show=True)

Traceback (most recent call last):

I think I have everything correctly installed and I didn't touch any file in my site packages

Please try to downgrade matplotlib to a version < 3.9
There seem to be incompatibilities with the latest major matplotlib version.
We will fix this in the next CommonRoad-IO release.
See here for the corresponding issue.

thank you, I also just realized matplotlib has released 3.9 a few days ago. I have downgraded to 3.8.3 and it works fine now!
