KeyError：“ [Int64Index（[... dtype ='int64'，length = 802）]都不存在

Question

使用keras时如何处理该索引问题？看着我的形状，一切看起来都很正常：

X = DF.iloc[:, 0:10]
Y = DF.iloc[:, 10:15]

X.shape, Y.shape

((1003, 10), (1003, 5))

X e Y：

培训：

for train, test in kfold.split(X,Y):

    model = Sequential()
    model.add(Dense(10,
                kernel_regularizer=l2(0.001),
                kernel_initializer=VarianceScaling(), 
                activation='sigmoid',
                name='hidden-input'))
    model.add(Dense(5, 
                kernel_regularizer=l2(0.001),
                kernel_initializer=VarianceScaling(),                 
                activation='sigmoid',
                name='output'))
    
    model.compile(loss='mse', optimizer='adam', metrics=['mse'])
    
    model.fit(X[train], Y[train], epochs=50, batch_size=5, verbose = 0,
              validation_data=(X[test], Y[test]))

    scores = model.evaluate(X[test], Y[test], verbose=0)
    print("%s: %.2f%%" % (model.metrics_names[1], scores[1]*100))
    cvscores.append(scores[1] * 100)

输出：
