ValueError: Error when checking input: expected input_1 to have 2 dimensions, but got array with sha

ValueError: Error when checking input: 
expected input_1 to have 2 dimensions, 
but got array with shape (69, 43, 1)

在跑神经网络时候出现的这个错误，感觉是最开始输入或者某一层输入的问题，发现把inpt = Input(shape=(43,)) 改成inpt = Input(shape=(43,1)) 就OK了
