Liveness Detection with OpenCV

Experimenting with Liveness Detection with OpenCV

macOS (same error in Windows below + same solution)

Traceback (most recent call last):
  File "train_liveness.py", line 114, in <module>
    plt.plot(np.arange(0, EPOCHS), H.history["acc"], label="train_acc")
KeyError: 'acc'

Convolutional Neural Net-Keras-val_acc Keyerror ‘acc’

SOLUTION

from keras source :
warnings.warn('The “show_accuracy” argument is deprecated, ’
'instead you should pass the “accuracy” metric to ’
‘the model at compile time:\n’
‘model.compile(optimizer, loss, ' 'metrics=["accuracy"])’)

The right way to get the accuracy is indeed to compile your model like this:

model.compile(loss=‘categorical_crossentropy’, optimizer=‘adadelta’, metrics=[“accuracy”])

Windows 10 + Anaconda3-5.3.1-64 bit + OpenCV-4.1.2-py37 (3.7.4)
