tf.errors.FailedPreconditionError

Class FailedPreconditionError

Inherits From: OpError

Defined in tensorflow/python/framework/errors_impl.py.

See the guide: Running Graphs > Error classes and convenience functions

Operation was rejected because the system is not in a state to execute it.

This exception is most commonly raised when running an operation that reads a tf.Variable before it has been initialized.

Properties

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.OpError.node_def to discover information about the op.

Returns:

The Operation that failed, or None.
