我在Python中有以下部分代码：
model.summary()
model.compile(loss='categorical_crossentropy', optimizer=optim, metrics=['accuracy'])
history = model.fit(x_train, y_train_onehot, batch_size=b_size, epochs=epoch, verbose=1, validation_split=0.2)
score = model.evaluate(x_test, y_test_onehot)
print("score: ",score[0])
print("accuracy: ",score[1])
y_pred = model.predict(x_test)
failed_pred = np.where((np.argmax(y_pred, axis=1) !=
np.argmax(y_test_onehot, axis=1)))
print("failed_pred")
x_test_prim = x_test[index]
print("x_test_prim.shape: ",x_test_prim.shape)
img_usable = np.expand_dims(x_test_prim, axis=0)
img_to_show = np.reshape(x_test_prim, (28,28))
plt.imshow(img_to_show)
print(img_usable.shape)
pred_prim = model.predict_classes(img_usable)
print("The prediction: ",pred_prim)
print("The reality: ",y_test[index])
如何在tkinter GUI中打印每个打印fn？ 有没有办法在未来的程序中调用这个fn？
