I am trying to train resnet using COCO dataset However I am not getting any idea of the label format of cntk.. How should I format COCO dataset label...?

There are different datasets for different tasks in COCO. For basic image classification task, please follow this tutorial to prepare CTNK data reader: https://cntk.ai/pythondocs/CNTK_201A_CIFAR-10_DataLoader.html# If more complex input is required, you can create a composite reader following this: https://docs.microsoft.com/en-us/cognitive-toolkit/BrainScript-and-Python---Understanding-and-Extending-Readers

I recommend preparing data in CNTK reader format for two reasons: 1) Very high throughput and GPU utilization; 2) Easy scaling across multiple workers; <= why I prefer CNTK above other frameworks.
