使用 conda 或 pip 在 Windows 上安裝 conda

Question

我正在嘗試在我的窗口上安裝 pytorch。

首先，我從這里得到命令conda install pytorch torchvision cpuonly -c pytorch

(PyTorch Build:Stable(1.3);Your OS:Windows;Package:Conda;Language:Python3.6;CUDA:None), there are some problems described as followings:
**(python36) C:\Users\li_dan0109>conda install pytorch torchvision cpuonly -c pytorch
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

and use the search bar at the top of the page.**

然后我也通過命令pip3 install torch==1.3.1+cpu torchvision==0.4.2+cpu -f https://download.pytorch.org/whl/torch_stable.html切換 pip install 然后我遇到了這個錯誤：

**(python36) C:\Users\li_dan0109>pip3 install torch==1.3.1+cpu torchvision==0.4.2+cpu -f https://download.pytorch.org/whl/torch_stable.html
Looking in links: https://download.pytorch.org/whl/torch_stable.html
ERROR: Could not find a version that satisfies the requirement torch==1.3.1+cpu (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2)
ERROR: No matching distribution found for torch==1.3.1+cpu**

我真的不知道如何解決它，請幫助我，非常感謝！

Answer 1

要安裝 pytorch，請按照以下兩個步驟操作。

首先運行這個命令

C:\Users\User>conda install PyTorch -c PyTorch

然后運行此代碼

C:\Users\User>pip3 install torchvision

Answer 2

看起來您可能安裝了 32 位 Python，在這種情況下，您的問題是： #16633 。

請注意， pyTorch 不適用於 32 位系統。

請使用 Windows 和 Python 64 位版本。
