Key error ''accuracy"

[hxapartners]

KeyError: 'accuracy'

Here is the code
model.compile(loss='categorical_crossentropy',
optimizer=optimizers.RMSprop(),
metrics=['accuracy'])
"""""rest of code not shown here. """""""""""""""
"""
Tensorboard log
"""
target_dir = "../models/weights-improvement-{epoch:02d}-{accuracy:.2f}.hdf5"
if not os.path.exists(target_dir):
os.mkdir(target_dir)
model.save('../models/model.h5')
model.save_weights('../models/weights.h5')

checkpoint = ModelCheckpoint(target_dir, monitor='accuracy', verbose=1, save_best_only=True, mode='max')

callbacks_list = [checkpoint]

model.fit_generator(
train_generator,
steps_per_epoch=nb_train_samples//batch_size,
epochs=epochs,
shuffle=True,
validation_data=validation_generator,
callbacks=callbacks_list,
validation_steps=nb_validation_samples//batch_size)

There is an error with the checkpoint as it does not recognize the key 'accuracy'. It is the same key used in compile of the model above as well.

What could be the issue her ?

hi @hxapartners which version of tensorflow is installed on your system?
