Pre-trained models and datasets built by Google and the community WebApr 15, 2024 · Let tensor A have M rows and N columns and consider the sum operation for simplicity. The shape of A is (M, N). If dim=0 is specified, then the vectors A[0,:], A[1,:], ..., A[M-1,:] are summed elementwise and the result is another tensor with 1 row and N columns. Notice that only the 0th dimension’s indices vary from 0 throughout M-1.
