# tf.errors.NotFoundError

## Class NotFoundError

Inherits From: OpError

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

Raised when a requested entity (e.g., a file or directory) was not found.

For example, running the tf.WholeFileReader.read operation could raise NotFoundError if it receives the name of a file that does not exist.

## 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.
