TensorFlow does not record events

Question

The following is a snippet of the code that I use to monitor events when training DNNRegressor. I'm running from a Jupyter laptop.

During training, I get the following errors in the terminal:

E tensorflow / core / util / events_writer.cc: 162] The event file /Users/eran/Genie/PNP/TB/events.out.tfevents.1473067505.Eran has disappeared. E tensorflow / core / util / events_writer.cc: 131] Failed to clear 2498 events before /Users/eran/Genie/PNP/TB/events.out.tfevents.1473067505.Eran

def add_monitors():
     validation_metrics = {'MeanSquaredError': tf.contrib.metrics.streaming_mean_squared_error}
     monitors = learn.monitors.ValidationMonitor(valid_X, valid_y, every_n_steps=50, metrics=validation_metrics)
     return [monitors]
      regressor = learn.DNNRegressor(model_dir='/Users/eran/Genie/PNP/TB', 
                                hidden_units=[32,16], feature_columns=learn.infer_real_valued_columns_from_input(X),        
 optimizer=tf.train.ProximalAdagradOptimizer(learning_rate=0.1),       
 config=learn.RunConfig(save_checkpoints_secs=1))
     monitors = add_monitors()
     regressor.fit(X, y, steps=10000, batch_size=20, monitors=monitors)

Any ideas? When I open TensorBoard, I do not see any registered events.

Answer 1

log_dir=path_to_events_file

, , tf.gfile.DeleteRecursively(log_dir);tf.gfile.MakeDirs(log_dir). , tf .

Answer 2

Windows, :

model_dir='C:\\Users\\eran\\Genie\\PNP\\TB'
