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 … Weba np.ndarray. The array whose axes should be reordered. source int or sequence of int.
