RuntimeError：PyTorch 目前不提供 PyPI 包

Question

我正在尝试运行这个 https://github.com/shariqiqbal2810/MAAC 存储库，它有一个名为 torch 的模块

import torch as McLawrence
from torch.autograd import Variable

我正在使用python版本3.7.1，我在win10上降级到3.6.5 我尝试使用

pip install torch
pip install pytorch
pip install torchvision

我把torch改成pytorch

我进入他们的网站https://pytorch.org/ 并尝试了所有使用pip 的建议，例如

pip3 install https://download.pytorch.org/whl/cu80/torch-1.0.0-cp36-cp36m-win_amd64.whl
pip3 install torchvision

我阅读了与此问题相关的每条评论

我在这里阅读了大部分答案

但我仍然收到相同的消息：

Answer 1

从 PyTorch 轮子安装应该可以工作。但是，问题是 pip 使用缓存的 pytorch 来安装它，如 GitHub here 所述。

Collecting pytorch
  Using cached https://files.pythonhosted.org/packages...

在 Windows 上 removing 来自 %LocalAppData%\pip\Cache 的 pip 缓存或使用 --no-cache-dir 禁用它可以解决以下问题：

pip3 --no-cache-dir install https://download.pytorch.org/whl/cu80/torch-1.0.0-cp36-cp36m-win_amd64.whl

Answer 2

为了顺利安装 PyTorch，请在 PyTorch 登录页面上使用他们的选项选择器： https://pytorch.org/ 然后根据他们的建议复制并运行 pip 命令（或其他命令）。
