Hi,
I want to sample at random from a tensor. For uniform distribution I use:
auto randtensor = torch::rand({100,1}); //Some tensor to sample from:

auto indices = torch::randint(0, 100, 10, torch::TensorOptions().dtype(torch::kInt64)); // 10 uniformly distributed random indices

auto random_sample = randtensor.index_select(0,indices); //10 random elements from randtensor, uniformly distributed

Now, instead of using a uniform distribution, I want to use an exponential distribution. Is there a way to generate random indices from an exponential distriburtion?
Thanks!
