Witryna11 kwi 2024 · To avoid the effect of shared storage we need to copy () the numpy array na to a new numpy array nac. Numpy copy () method creates the new separate storage. import torch a = torch.ones ( (1,2)) print (a) na = a.numpy () nac = na.copy () nac [0] [0]=10 print (nac) print (na) print (a) Output: Witryna8 maj 2024 · All source tensors are pushed to the GPU within Dataset __init__, and the resultant reshaped and fetched tensors live on the GPU. I’d like reassurance that the fetched tensors are truly views of slices of the source tensors, or at least that Dataset or Dataloader aren’t temporarily copying data to the CPU and back again. Any advice?
