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

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

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. Note: 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.
