raise TypeError("can't convert Operation '{}' to Tensor".format(self.name)) TypeError: can't convert Operation 'teller/embedding/Variable/Read/Identity' to Tensor

This error occurs when the TensorFlow code tries to convert an operation to a tensor. In this specific case, it is trying to convert the operation 'teller/embedding/Variable/Read/Identity' to a tensor, which is not possible.

Possible reasons for this error could be:

1. The operation is not defined correctly.
2. The operation is not compatible with the tensor conversion.
3. There is a mismatch between the operation and the expected input.

To resolve this error, you need to check your TensorFlow code and make sure that the operation is defined correctly and is compatible with the tensor conversion. Also, check if there is any mismatch between the operation and the expected input.
