Pycocotools package error in "16_mmdet" pipeline

[swapnil-ahlawat]

While training the model on Google colab notebook using "16_mmdet" pipeline, I got the following error:
AttributeError: COCO object has no attribute get_cat_ids

I was able to correct it by reinstalling the specific version of pycocotools package and restarting the runtime using the following command:
!pip install "git+https://github.com/open-mmlab/cocoapi.git#subdirectory=pycocotools"

This seems to be a version-specific issue in the installation file. Kindly rectify it.
