WebUsage in PyTorch Let’s take a look at a single training step. For this example, we load a pretrained resnet18 model from torchvision . We create a random data tensor to represent a single image with 3 channels, and height & width of 64, and its corresponding label initialized to some random values. Label in pretrained models has shape (1,1000). WebMar 31, 2024 · PyTorch example: freezing a part of the net (including fine-tuning) Raw freeze_example.py import torch from torch import nn from torch. autograd import Variable import torch. nn. functional as F import torch. optim as optim # toy feed-forward net class Net ( nn.

WebJul 8, 2024 · The closest to a MWE example Pytorch provides is the Imagenet training example. Unfortunately, that example also demonstrates pretty much every other feature Pytorch has, so it’s difficult to pick out what pertains to distributed, multi-GPU training. Apex provides their own version of the Pytorch Imagenet example.
