我正在嘗試使用 python zincbase，並且需要在 Windows 上安裝 pytorch。執行時

pip install torch

我收到一條錯誤訊息

如何安裝 pytorch？

答案1

您只需造訪 PyTorch 網站即可pytorch.org

然後轉到“開始”頁面。您將看到一個有趣的線上工具，您可以在其中選擇不同的選項，並且它將提供安裝“torch”的正確命令。

就像下面這張圖一樣：

在此輸入影像描述

正如您在上面的選擇中所看到的，安裝火炬的命令將是以下結果：

pip3 install torch==1.3.1+cpu torchvision==0.4.2+cpu -f https://download.pytorch.org/whl/torch_stable.html

答案2

與其他函式庫不同，我們不能只使用 pip install torch 指令在本機上安裝 PyTorch。

去https://pytorch.org網站並選擇您的電腦和環境，它將為您提供運行命令，如下所示 -

pip3 install torch===1.2.0 torchvision===0.4.0 -f https://download.pytorch.org/whl/torch_stable.html

對於 Python 3.7 -

pip3 install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp37-cp37m-win_amd64.whl pip3 install torchvision
