Sagemaker debugger hooks for keras unet

I am utilising debugger hooks for custom model utilising **keras-unet** library. This library is built over tensorflow and keras.I am trying to include a debugger hook for that and I have utilised hooks as per the link[https://docs.aws.amazon.com/sagemaker/latest/dg/debugger-bring-your-own-container.html]( https://docs.aws.amazon.com/sagemaker/latest/dg/debugger-bring-your-own-container.html). I am using Tensorflow 1.15.2 inbuilt container to train my model ,while calling estimator.fit, I am getting the following error :

```
with open(path) as json_config_file:
FileNotFoundError: [Errno 2] No such file or directory: '/opt/ml/input/config/debughookconfig.json'
```

I have already included the hook in the callbacks in the training script. Kindly guide.
