problem in instance-segmentation

I have 53 RGB images and their corresponding annotation in coco JSON format. I used the colab notebook (instance-segmentation) from the example and just replaced datasets with mine. It starts the processes, generated few images andgives the following error. I can't figure it out. Please help. I am running it on google colab pro.
