从 requirements.txt 安装 PyTorch

Question

Torch 文档说使用

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

安装最新版本的 PyTorch。这在我手动执行时有效，但是当我将它添加到 req.txt 并执行 pip install -r req.txt 时，它失败并显示 ERROR: No matching distribution.

编辑：添加来自 req.txt 的整行并在此处出错。

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)

Answer 1

在火炬

之前的requirements.txt中添加--find-links

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

torch==1.2.0+cpu

Answer 2

你可以这样做：

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

只需将您的 PyTorch 要求放在 req.txt 中，如下所示：

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

对我来说很好:)
