tf.errors.UnavailableError

View source on GitHub

Raised when the runtime is currently unavailable.

Inherits From: OpError

tf.errors.UnavailableError(
    node_def, op, message
)

This exception is not currently used.

Attributes:

• error_code: The integer error code that describes 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.

  N.B. If the failed op was synthesized at runtime, e.g. a Send or Recv op, there will be no corresponding tf.Operation object. In that case, this will return None, and you should instead use the tf.errors.OpError.node_def to discover information about the op.
