Hi all !

Then I try install mmocr and do mim install mmdet I receive mistake with pycocotools in Windows 10.

I try use two ways of install mmocr:

mim install mmocr

git clone https://github.com/open-mmlab/mmocr.git cd mmocr pip install -v -e .

Also I try that: mim install mmdet

By all the ways I receive next mistale:

I got the same error，it seem that the pycocotools cannot be installed in WINDOWS. You can downgrade your python version to 3.8 or older. Then run "pip install git+https://github.com/philferriere/cocoapi.git#subdirectory=PythonAPI". Just try it, maybe it will work.

You can also try installing pycocotools using conda if you're in a conda environment:

conda install pycocotools -c conda-forge

And then proceed with installing mmdet
