Mmdetection: AttributeError: module 'pycocotools' has no attribute '__version__'

[jialeli1]

Hi, I installed mmdet according to the instructions, but I still encountered this problem.

File "/home/lijiale/mmdet_install/mmdetection/mmdet/datasets/coco.py", line 19, in
assert pycocotools.__version__ >= '12.0.2'
AttributeError: module 'pycocotools' has no attribute '__version__'

I also tried to install pycocotools from open-mmlab/cocoapi, but I found that it installed mmpycocotools. When I run _pip list | grep pycocotools_, I found that there are two pycocotools.

(open-mmlab) lijiale@ImageLab:~/mmdet_install/mmdetection3d$ pip list | grep pycocotools
mmpycocotools 12.0.2
pycocotools 2.0.2

Maybe this is the problem, but I don't know the specific reason. Could someone help me?

pip uninstall pycocotools

Please use the mmlab maintained pycocotools. To do that, you should first pip uninstall pycocotools and pip install mmpycocotools.

import pycocotools pycocotools.__file__, to locate the pycocotools path which is used in current python environment. Then uninstall it.
