L'objet 'séquentiel' n'a aucun attribut '_in_multi_worker_mode'

J'ai essayé d'utiliser Google Colab Ressources pour enregistrer mes poids de modèle CNN et je reçois cette erreur. J'ai essayé de googler, mais rien n'aide.

L'objet 'séquentiel' n'a aucun attribut '_in_multi_worker_mode'

Mon code:

checkpoint_path = "training_1/cp.ckpt"
checkpoint_dir = os.path.dirname(checkpoint_path)
cp_callback = tf.keras.callbacks.ModelCheckpoint(checkpoint_path, save_weights_only=True, verbose=1)


cnn_model = Sequential()
cnn_model.add(Conv2D(filters = 64, kernel_size = (3,3), activation = "relu", input_shape = Input_shape ))
cnn_model.add(Conv2D(filters = 64, kernel_size = (3,3), activation = "relu"))
cnn_model.add(MaxPooling2D(2,2))
cnn_model.add(Dropout(0.4))

cnn_model = Sequential()
cnn_model.add(Conv2D(filters = 128, kernel_size = (3,3), activation = "relu"))
cnn_model.add(Conv2D(filters = 128, kernel_size = (3,3), activation = "relu"))
cnn_model.add(MaxPooling2D(2,2))
cnn_model.add(Dropout(0.3))


cnn_model.add(Flatten())

cnn_model.add(Dense(units = 512, activation = "relu"))
cnn_model.add(Dense(units = 512, activation = "relu"))

cnn_model.add(Dense(units = 10, activation = "softmax"))

history = cnn_model.fit(X_train, y_train, batch_size = 32,epochs = 1, 
shuffle = True, callbacks = [cp_callback])

Veuillez vérifier si votre version de TENSORFLOW correspond au dernier one.in mon cas, l'erreur a été résolue lors de son mise à jour à 2.1.0.
