Moved from SpesRobotics/teleop-pro#7 because the fix belongs in the public teleop core.
Summary
teleop-pro Webots imports teleop.utils.jacobi_robot.JacobiRobot. That module imports matplotlib.pyplot at module import time, even when visualization is unused.
On a machine with user-site NumPy 2.5.0 and system Matplotlib compiled against NumPy 1.x, the eager Matplotlib import crashes the Webots bridge before robot logic starts.
Observed error
A module that was compiled using NumPy 1.x cannot be run in NumPy 2.5.0
ImportError: numpy.core.multiarray failed to import
Expected behavior
Importing JacobiRobot for non-visual servoing should not import Matplotlib.
Acceptance criteria
- Move
matplotlib.pyplot import into the visualization methods that actually use it.
from teleop.utils.jacobi_robot import JacobiRobot works without Matplotlib being importable.teleop-pro Webots bridge starts without requiring a NumPy downgrade solely because of Matplotlib.- Add or update a lightweight import test if practical.
