WebFeb 24, 2024 · Notes on the kernel above: the kernel above treats nbatch and channels as one dimension (e.g. channels = nbatch * channels), since logically they are generic;; at:parallel_for is a wrapper on parallelization runtime (OpenMP or TBB, default is OpenMP), you can take it simply as #pragma omp parallel;; at::parallel_for accepts 4 params: … Webnumpy.transpose. #. Returns an array with axes transposed. For a 1-D array, this returns an unchanged view of the original array, as a transposed vector is simply the same vector. To convert a 1-D array into a 2-D column vector, an additional dimension must be added, e.g., np.atleast2d (a).T achieves this, as does a [:, np.newaxis] .
