Je suis nouveau sur tensorflow et tflearn et j'obtiens cette erreur lors de l'apprentissage du modèle.InvalidArgumentError: Vous devez alimenter une valeur pour le tenseur d'espace réservé 'input_1/X' avec dtype float
InvalidArgumentError (see above for traceback): You must feed a value for placeholder tensor 'input_1/X' with dtype float
[[Node: input_1/X = Placeholder[dtype=DT_FLOAT, shape=[], _device="/job:localhost/replica:0/task:0/cpu:0"]()]]
Voici mon code de préférence. Où train et test sont des tableaux numpy ayant un premier élément comme image et un second élément comme étiquette. J'essaye d'adapter mon modèle par cette ligne.
model.fit({'input': X}, {'targets': Y}, n_epoch=5, validation_set=({'input': test_x}, {'targets': test_y}), snapshot_step=500, show_metric=True, run_id=MODEL_NAME)
Ceci est l'erreur complète que je reçois:
