ValueError: Tried to convert 'input' to a tensor and failed. Error: None values not supported.

I have tried to apply DIRNet on Brain Haemorrhage Datasets but encountered an error while training .I could resolve the Error: ValueError: Tried to convert 'input' to a tensor and failed. Error: None values not supported.' .Need your recommendation if any .I am using Tensorflow 1.15.2.
