Snažím se zařadit psi a kočky. Zde je odkaz na datový soubor na Kaggle pokud chcete reprodukovat to, co sami: https://www.kaggle.com/tongpython/cat-and-dog.
V model.fit() funkce, jsem zadaný epochs=15. Ale když jsem spustit to, to jde dál, dokud je to hotové 1/15 epoch. Podívejte se:
Epoch 1/15

Víte, proč se to děje a co můžu udělat, aby se můj 15 epoch za přesnost?
