When running:pip install "git+https://github.com/open-mmlab/cocoapi.git#subdirectory=pycocotools"

I get "Running setup.py install for mmpycocotools did not run successfully.

Please help, thanks in advance.

It could be a version issue with the Cython library. Try using a lower version: pip install cython==0.29.36

This solved my problem when install mmdetection 2.1.0

If you would like to use cython >= 3, delete these two lines,

cocoapi/pycocotools/pycocotools/_mask.pyx

Lines 1 to 2 in 01f805c

	# distutils: language = c
	# distutils: sources = ../common/maskApi.c
