报错‘function’object has no attribute‘XXXX’

报错原因：可能是方法后面没有加 ( )

# train_x为dataframe
train_X=train_x.to_numpy
train_X=train_X.reshape((train_X.shape[0],train_X.shape[1],1))

#运行结果
 2 train_X=train_x.to_numpy
----> 3 train_X=train_X.reshape(())

AttributeError: 'function' object has no attribute 'reshape'

正确写法：

train_X=train_x.to_numpy()
train_X=train_X.reshape((train_X.shape[0],train_X.shape[1],1))

运行成功

以前不曾注意到的错误，细心啊！细心！
