tf.errors.AlreadyExistsError

Raised when an entity that we attempted to create already exists.

Inherits From: OpError

tf.errors.AlreadyExistsError(
    node_def, op, message, *args
)

An API raises this this error to avoid overwriting an existing resource, value, etc. Calling a creation API multiple times with the same arguments could raise this error if the creation API is not idempotent.

For example, running an operation that saves a file (e.g. tf.saved_model.save) could potentially raise this exception if an explicit filename for an existing file was passed.

error_code The integer error code that describes the error. experimental_payloads A dictionary describing the details of the error. message The error message that describes the error. node_def The NodeDef proto representing the op that failed. op The operation that failed, if known.
