拒绝for循环,从take_along_axis开始 https网络安全numpyhtml 在前一篇文章中,我们提到了关于Numpy中的各种取index的方法,可以用于取出数组里面的元素,也可以用于做切片,甚至可以用来做排序。但是遇到对于高维矩阵的某一个维度取多个值的时候,单纯的使用下标已经无法完成相关的操作了。如果找不到相应的接口,对于性能要求不...

For any deep space mission we'll end up coasting most of the way, and 90 km/s is some pretty fast coasting. Even this low end torchship lets you take retrograde hyperboloid orbits, which is Isaac Newton's way of saying you can pretty much point & scoot. You will truck along at 1 ...

以上切片方式相对规则,对于不规则的切片提取,可以使用torch.index_select,torch.take,torch.gather,torch.masked_select。 3.2,gather 和 torch.index_select 算子 gather算子的用法比较难以理解,在翻阅了官方文档和网上资料后,我有了一些自己的理解。 1,gather是不规则的切片提取算子(Gathers values along an axis spe...
