When run, reports an InvalidArgument error if tensor has any values that are not a number (NaN) or infinity (Inf). Otherwise, passes tensor as-is.

Args:

• tensor: A Tensor. Must be one of the following types: bfloat16, half, float32, float64.
• message: A string. Prefix of the error message.
• name: A name for the operation (optional).

Returns:

A Tensor. Has the same type as tensor.
