Translation Model Predictions: TypeError: Object of type 'EagerTensor' is not JSON serializable

[echan00]

I have followed the translation colab notebook tutorial as suggested by this repository

After exporting the model and uploading it to Google's AI Platform engine for online prediction, I am having trouble making requests to the model.

I believe the input to the translation model is a tensor of the source text. But I am receiving an error that TypeError: Object of type 'EagerTensor' is not JSON serializable

def encode(input_str, output_str=None):
  """Input str to features dict, ready for inference"""
  inputs = encoders["inputs"].encode(input_str) + [1]  # add EOS id
  batch_inputs = tf.reshape(inputs, [1, -1, 1])  # Make it 3D.
  return {"inputs": batch_inputs}

enfr_problem = problems.problem(PROBLEM)
encoders = enfr_problem.feature_encoders(DATA_DIR)

encoded_inputs = encode("Some text")
model_output = predict_json('project_name','model_name', encoded_inputs,'version_1')["outputs"]

I've tried converting the tensor to numpy but still no luck. Could someone point me in the right direction?
