# tf.errors.PermissionDeniedError

### class tf.errors.PermissionDeniedError

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

Raised when the caller does not have permission to run an operation.

For example, running the tf.WholeFileReader.read operation could raise PermissionDeniedError if it receives the name of a file for which the user does not have the read file permission.

## 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.

## Methods

### __init__(node_def, op, message)

Creates a PermissionDeniedError.
