The shape of the input 2D average pooling layer should be [N, C, H, W]. Transpositions which interchange the sparse dimensions of a SparseCSR or SparseCSC layout tensor will result in the layout changing between the two options. Representation of board is 1x6x7 array: [[[0 0 0 0 0 0 0] [0 0 0 0 0 0 0] [0 0 0 0 0 0 0] [0 Nov 5, 2018 · The issue is that your numpy array has dtype=object, which might come from mixed dtypes or shapes, if I’m not mistaken. , indices for sequence length dimension). # x is my data which is a nd-array # You have to convert your tensor to nd-array before using scikit Nov 6, 2019 · Tensors fundamentally cannot hold arbitrary objects, but assuming you have a 1d array of 2d tensors, you can use stack to get a 3d Tensor. For now I got the result doing the following, but it seems involuted. Nov 7, 2017 · Let’s say I have a 2d tensor A A = [[0,1,2], [3,4,5], [6,7,8]] I want to copy each row 10 times and stack them, which will then give me a 3d tensor. For ex- M = 2 , N = 4 , K = 2 A = [[[1,2],[3,4],[5,6],[7,8]] , [[9,10],[11,12],[13,14],[15,16]]] Index = [0 I'm going to create a tensor that stacks up the tensor that comes out of the above input_tensor by moving the Window in size (2,2). ij kh av ds pm vk yt fj dp lb
