Install PyTorch from requirements.txt

Question

Torch documentation says use

pip install torch==1.4.0+cpu torchvision==0.5.0+cpu -f https://download.pytorch.org/whl/torch_stable.html

to install the latest version of PyTorch. This works when I do it manually but when I add it to req.txt and do pip install -r req.txt, it fails and says ERROR: No matching distribution.

Edit: adding the whole line from req.txt and error here.

torch==1.4.0+cpu -f https://download.pytorch.org/whl/torch_stable.html

torchvision==0.5.0+cpu -f https://download.pytorch.org/whl/torch_stable.htmltorch==1.4.0+cpu

ERROR: Could not find a version that satisfies the requirement torch==1.4.0+cpu (from -r requirements.txt (line 1)) (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2, 0.3.1, 0.4.0, 0.4.1, 1.0.0, 1.0.1, 1.0.1.post2, 1.1.0, 1.2.0, 1.3.0, 1.3.1, 1.4.0)

Add --find-links in requirements.txt before torch

--find-links https://download.pytorch.org/whl/torch_stable.html

torch==1.2.0+cpu

You can do something like that:

$ pip install -r req.txt --find-links https://download.pytorch.org/whl/torch_stable.html

Just put your PyTorch requirements in req.txt like this:

torch==1.4.0+cpu

torchvision==0.5.0+cpu

Answer 3

-f https://download.pytorch.org/whl/torch_stable.html 
torch==1.4.0+cpu 
-f https://download.pytorch.org/whl/torch_stable.html
torchvision==0.5.0+cpu

worked fine for me 🙂

Answer 4

To get the cuda version that I needed (instead of whatever the repos serve up), I converted the cuda-specific installation command from pytorch:

pip3 install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu116

into this at the top of requirements.txt:

--extra-index-url https://download.pytorch.org/whl/cu116
torch
torchvision
torchaudio

Then I do the usual pip install -r requirements.txt and when I import torch and run torch.version.cuda inside python, I get ‘11.6’ as I wanted.

Answer 5

For me, this requirement.txt worked for CPU version installation

--extra-index-url https://download.pytorch.org/whl/cpu
torch
torchvision
