Improve this question i am trying to make an ai with the mnist dataset from torchvision and makeing it with pytorch, but when i type some of the code that shuffle the data, and run it, it say: trainset = torch.utils.data.Dataloader(train, batch_size=10, shuffle=True) AttributeError:

问题 I am trying to use a pre-trained model. Here's where the problem occurs Isn't the model supposed to take in a simple colored image? Why is it expecting a 4-dimensional input? RuntimeError Traceback (most recent call last) <ipython-input-51-d7abe3ef1355> in <module>() 33 34 # Forward pass the data through the model ---> 35 output = model(data) 36 init_pred = output.max(1, keepdim=True)[1] # get the index of the max log-probability 37 5 frames /usr/local/lib/python3.6/dist-packages/torch/nn

问题 This is my main.py : import torchvision input("Press key") It runs correctly in the command line: python main.py I need an executable for windows. So I did : pyinstaller main.py But when I launched the main.exe , inside /dist/main I got this error: Traceback (most recent call last): File "main.py", line 1, in <module> ... (omitted) File "site-packages\torchvision\ops\misc.py", line 135, in <module> File "site-packages\torchvision\ops\misc.py", line 148, in FrozenBatchNorm2d File "site

问题 I'm looking at the documentation, and here is their example. I cannot understand how this example corresponds to their explanation: "Returns a new tensor with a dimension of size one inserted at the specified position." >>> x = torch.tensor([1, 2, 3, 4]) >>> torch.unsqueeze(x, 0) tensor([[ 1, 2, 3, 4]]) >>> torch.unsqueeze(x, 1) tensor([[ 1], [ 2], [ 3], [ 4]]) 回答1: If you look at the shape of the array before and after, you see that before it was (4,) and after it is (1, 4) (when second

问题 I am referring to the models that can be found here: https://pytorch.org/docs/stable/torchvision/models.html#torchvision-models 回答1: As, @dennlinger mentioned in his answer : torch.utils.model_zoo, is being internally called when you load a pre-trained model. More specifically, the method: torch.utils.model_zoo.load_url() is being called every time a pre-trained model is loaded. The documentation for the same, mentions: The default value of model_dir is $TORCH_HOME/models where $TORCH_HOME

问题 I am trying to install PyTorch but every time it throws the same error ( ModuleNotFoundError: No module named ‘tools.nnwrap’). This is what is typed: pip install torch This is what I get every time: Collecting torch Using cached https://files.pythonhosted.org/packages/f8/02/880b468bd382dc79896eaecbeb8ce95e9c4b99a24902874a2cef0b562cea/torch-0.1.2.post2.tar.gz Requirement already satisfied: pyyaml in c:\users\user\appdata\local\programs\python\python37-32\lib\site-packages (from torch) (5.1.2)

问题 I am trying to install Pytorch via pip on ubuntu 18.04.I have python 3.6 and my laptop is HP-Pavilion notebook 15 The installation seems to be right because i get the message: Installing collected packages: torch, torchvision Successfully installed torch-1.3.1+cpu torchvision-0.4.2+cpu i run the verification code and it is ok from __future__ import print_function import torch x = torch.rand(5, 3) print(x) However, when i close the terminal or reboot and try to run he same code i get the error
