an additional dimension must be added, e.g.,np.atleast2d(a).Tachieves this, as doesa[:,np.newaxis]. For a 2-D array, this is the standard matrix transpose. For an n-D array, if axes
一、前言在进行深度学习的过程中,经常遇到permute函数,transpose函数,view函数,contiguous函数等,他们起什么作用,之间又有什么联系呢?二、主要内容2.1、permute函数和transpose函数Tensor.permute(a,b,c,d, …):可以对任意高维矩阵进行转置。例子见下:In[1]: torch.randn(2,3,4,5).permute(3,2,0, pytorch 深...

However, if we need to compute the mean of a stream of numbers, we would have to first assemble the array by reading from the stream and then call np.mean() on the resulting array, we would have to write some more code and hence, as an alternative, we can use the TensorFlow reduce...
4. One K × K block switch that permutes groups of N modes. 5. K N × N switches that perform arbitrary permutations of N modes. 6. One 2N × 2N switch that performs an arbitrary permutation of 2N modes. 7. O(N) four-mode interferometers for the satisfiability test....
