Theano-计算theano矩阵列表的元素明智和

Question

I have a list of theano matrices(using in a neural network implementation). I need to perform element wise sum on the corresponding elements.

Eg Input : x1 = [<TensorType(float64, matrix)>, <TensorType(float64, matrix)> , <TensorType(float64, matrix)>]

Output : <TensorType(float64, matrix)> -> which is the element wise sum of the 3 matrices.

Looked at a few posts but unable to figure out how to proceed. Please advice. Thanks in advance.

您可以在theano中使用扫描功能，并且必须确保列表中的每个矩阵都具有相同的形状。
