WebMethod 1: Using numpy.random.permutation. Approach: Call the permutation () function of the numpy.random module and pass the length of the given arrays to this function. This returns a randomly permuted range of 0 to len (array)-1. Let’s say that the result is stored in a variable shuffler. WebApr 9, 2024 · Thanks for sharing the code! Since GPU operations are executed asynchronously, you would have to synchronize the code manually before starting and stopping the timer via torch.cuda.synchronize() to get the real execution time. Otherwise you might be profiling the kernel launch times and blocking operations would accumulate the …
