Hi, my demo.py is based on mmdet.
Your code crash at line https://github.com/open-mmlab/mmdetection/blob/a637a552b0a43285cbcaf4d92eecad36326c8ca0/mmdet/core/visualization/image.py#L113
Maybe your matplotlib is not installed correctly.

Maybe your matplotlib is not installed correctly.

I met this problem and matplotlib has been installed correctly.
