At the end of unit 3 (mastering with ROS: jackal), in pedestrian_detector.py script is called the imutils library, see in the script:
from imutils.object_detection import non_max_suppression
from imutils import paths
however, the command window produces the following error:
ImportError: No module named imutilsimutils
can you help me?
I apologize for this error. This is probably because
imutils is not installed globally. We’ll look into that.
In the meantime, you can work around this problem by running, from the shell:
# ignore any warning messages as long as the install is successful
pip install imutils
PS: please don’t run the code within the notebook, run it from the terminal (shell).
