The run_values argument contains results of requested ops/tensors by before_run (). The run_context argument is the same one send to before_run call. run_context.request_stop () can be called to stop the iteration. If session.run () raises any exceptions then after_run () is not called. A SessionRunContext object.
Problems creating a SessionRunHook for early stopping One of the basic tutorials on the TensorFlow homepage uses a ValidationMonitor to implement early stopping. However, since monitors are deprecated, I wanted to try implementing it as a SessionRunHook instead.
A SessionRunHook extends session.run () calls for the MonitoredSession. Then some common SessionRunHook classes can be found here. A simple one is LoggingTensorHook but you might want to add the following line after your imports for seeing the logs when running: tf.logging.set_verbosity (tf.logging.INFO) Or you have option to implement your own ...
tf.train.SessionRunHook use (1) may be used tf has been pre-defined Hook, which is tf.train.SessionRunHook subclasses; as. StopAtStepHook: Set max_step or num_step for stopping iteration, the two can only set one; NanTensorHook: If the loss of value of Nan, stop training;

SessionRunHooks are useful to track training, report progress, request early. stopping and more. SessionRunHooks use the observer pattern and notify at the. following points: when a session starts being used.
after_run ( run_context, run_values ) Called after each call to run (). The run_values argument contains results of requested ops/tensors by before_run ().

"""A SessionRunHook extends `session.run()` calls for the `MonitoredSession`. SessionRunHooks are useful to track training, report progress, request early.
A SessionRunHook encapsulates a piece of reusable/composable computation that: can piggyback a call to `MonitoredSession.run()`. A hook can add any: ops-or-tensor/feeds to the run call, and when the run call finishes with success: gets the outputs it requested. Hooks are allowed to add ops to the graph in `hook.begin()`.

27.07.2018 · The “SessionRunHook” on the other hand can be used to construct an “EstimatorSpec” for each execution mode and is used each time train, evaluate or predict is called. Both the “Scaffold” and “SessionRunHook” provide certain functions that the Estimator class calls during use.
