Vstup 0 neslučitelné s vrstvou inception_v3 očekává, že tvar=(None, 299, 299, 3), nalézt tvar=(1, 229, 229, 3)

Jak převést tvar=(1, 299, 299, 3) se očekává, že tvar=(None, 299, 299, 3) krmit do vyškoleni vzniku v3 model.

POZNÁMKA: STEJNOU OTÁZKU BYLY PŘEDTÍM PTAL, ALE ODPOVĚĎ NENÍ DOSTATEČNĚ JASNÉ.

 img = tf.io.read_file(img)
  # decode image into tensor
img = tf.io.decode_image(img,channels=3) # hardcode for 3 channels to be compatible despite of the image type
  # resize the image
img = tf.image.resize(img,[229,229])
  # Scale Y/N
img = img/255.

img.shape

TensorShape([229, 229, 3])

instance = np.expand_dims(img, axis=0)

print(instance.shape)

(1, 229, 229, 3)

predictions = model(instance).numpy().argmax(axis=1)

Došlo k chybě, když se snaží získat predikce takto. ValueError: Vstup 0, je neslučitelná s vrstvou inception_v3: předpokládaný tvar=(None, 299, 299, 3), nalézt tvar=(None, 229, 229, 3) --------------------------------------------------------------------------- ValueError Traceback (poslední hovor poslední) v () ----> 1 předpovědi = model(instance).numpy().argmax(osa=1)

Podle odpovědí 01 jsem změnil kód takto a narazíte na nějaké podivné chyby.

img = tf.expand_dims(img,axis=0)
img = tf.keras.applications.inception_v3.preprocess_input(img)
predictions = model.predict(img).argmax(axis=1)

Nová chyba je následující
