ValueError: Ошибка при проверке ввода: ожидалось, что input_1 будет иметь форму (None, 65563), но получил массив с формой (374, 65536)

Question

У меня есть автоэнкодер, написанный на Керасе, показанный ниже. Я получаю следующую ошибку, и не знаю, как ее решить, есть идеи?

ValueError: Ошибка при проверке ввода: ожидается, что input_1 будет иметь форму (Нет, 65563), но получил массив с формой (374, 65536)

from keras.layers import Input, Dense, Flatten

# the size of the encoded represenatation
encoding_dimension = 784
# input placeholder
input_image = Input(shape=(65563,))
# the encoded representation of the input
encoded = Dense(encoding_dimension,activation='relu')(input_image)
# reconstruction of the input (lossy)
decoded = Dense(65563,activation='sigmoid')(encoded)
# map the input image to its reconstruction
autoencoder = Model(input_image,decoded)

# encoder model

# decoder model

# retrieve the last layer of the autoencoder model

for root, dirs, files in os.walk(training_directory):
    for file in files:
        image = cv2.imread(root + '/' + file)
        image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
        image = img_to_array(image)
        training_images.append(image)

training_images = numpy.array(training_images)

for root, dirs, files in os.walk(validation_directory):
    for file in files:
        image = cv2.imread(root + '/' + file)
        image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
        image = img_to_array(image)
        validation_images.append(image)

validation_images = numpy.array(validation_images)

# reshape data
training_images = training_images.reshape((len(training_images), numpy.prod(training_images.shape[1:])))
validation_images = validation_images.reshape((len(validation_images), numpy.prod(validation_images.shape[1:])))

autoencoder.compile(optimizer='adam',loss='binary_crossentropy')

autoencoder.fit(training_images,epochs=10,batch_size=20,shuffle=True,validation_data=(validation_images))

encoded_images = encoder.predict(validation_images)
decoded_images = decoder.predict(encoded_images)

Спасибо.

Запись 65563 вместо 65536 могла быть опечаткой, вызывающей проблему.
