Torch load numpyWhat is PyTorch? An open source machine learning framework. A Python package that provides two high-level features: Tensor computation (like NumPy) with strong GPU accelerationI never understood why people do things like > import numpy as np > import pandas as pd but are fine with using a different style at other times > import torch > import {whatever}. Why bother? Are people just used to importing numpy that way and dont want to bother changing? Did pandas start doing it just to be cool?If you are concerned with memory allocation, here is another answer on StackOverflow with a little more information. PyTorch's view function actually does what the name suggests - returns a view to the data. The data is not altered in memory as far as I can see. In numpy, the reshape function does not guarantee that a copy of the data is made or not. It will depend on the original shape of the ...Code 1: import torch import numpy as np a = [np.random.randint(0, 10, size=(7, 7, 3)) for _ in range(100000)] b = torch.tensor(np.array(a)) And code 2: import torch import numpy as np a = [np.random.randint(0, 10, size=(7, 7, 3)) for _ in range(100000)] b = torch.tensor(a, dtype=torch.float) The code 1 takes less than 1 second to execute (used ...Comparing Numpy, Pytorch, and autograd on CPU and GPU.
