从requirements.txt安装PyTorch

Question

火炬文件说明使用

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。当我手动执行此操作时，它会工作，但当我将其添加到req.txt并执行pip install -r req.txt时，它会失败并显示ERROR: No matching distribution

编辑：从req.txt添加整行并在此处出错

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)
ERROR: No matching distribution found for torch==1.4.0+cpu (from -r requirements.txt (line 1))

Answer 1

-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：）

Answer 2

在火炬前的requirements.txt中添加 find-links

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

torch==1.2.0+cpu

资料来源：https://github.com/pytorch/pytorch/issues/29745#issuecomment-553588171

Answer 3

你可以这样做：

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

只需将Pytork需求放在req.txt中，如下所示：

torch==1.4.0+cpu

torchvision==0.5.0+cpu
