[Task]: Unable to load tensorflow hub models using TFModelHandler

[AnandInguva]

What needs to happen?

Try to implement bert from TensorflowHub using TFModelHandlerTensor. I get the error

ValueError: Unable to load the TensorFlow model: 'tuple' object has no attribute 'startswith'. Make sure you've         saved the model with TF2 format. Check out the list of TF2 Models on         TensorFlow Hub - https://tfhub.dev/s?subtype=module,placeholder&tf-version=tf2.
