Irregular error “RuntimeError: Unable to create attribute (object header message is too large)”












0














I am saving weight of keras model on each better loss at the end of epoch



def save_best_weights_if_required(self, loss, acc):
if self.best_loss is None or loss<self.best_loss:
logger.info('Saving ''best_weights.h5''...')
self.save_weights('best_weights.h5')
self.best_acc = acc
self.best_loss = loss

def on_epoch_end(self, epoch, logs=None):
self.epoch_logs.append(logs)
self.save_best_weights_if_required(logs['val_loss'], logs['val_acc'])


As you see, the function is called many times with the same filename.



On first save it takes up to minutes to save. On next saves it does instantly.



Also I got error



File "/opt/anaconda3/envs/py35/lib/python3.5/site-packages/keras/engine/network.py", line 1104, in save
save_model(self, filepath, overwrite, include_optimizer)
File "/opt/anaconda3/envs/py35/lib/python3.5/site-packages/keras/engine/saving.py", line 175, in save_model

RuntimeError: Unable to create attribute (object header message is too large)


during one of the later saves.



How can it be? If the problem is with node names, then how it could save first times?



Why is it saving longer on first save?
