keras model.fit_generator错误。如何解决此问题？

Question

我已经检查了keras.fit_generator函数的文档，仍然找不到问题  我的笔记本电脑中的图书馆工作正常 我的代码：

# train the network
print("training network...")
sys.stdout.flush()
#class_mode ='categorical', # 2D one-hot encoded labels
H = model.fit_generator(aug.flow(Xtrain, trainY,batch_size=BS),
                    validation_data=(Xval, valY),
                    steps_per_epoch=len(trainX) // BS,
                    epochs=EPOCHS, verbose=1)

# save the model to disk
print("Saving model to disk")
sys.stdout.flush()
model.save("/tmp/mymodel")

我的代码出现以下错误：
