RuntimeError: PyTorch does not currently provide packages for PyPI

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改成了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

中与此问题相关的所有评论

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 wheel 安装应该有效。但是，问题是 pip 正在使用缓存的 pytorch 来安装它，如 GitHub here.

中所述

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

removing Windows 上 %LocalAppData%\pip\Cache 的 pip 缓存或使用 --no-cache-dir 禁用它可以解决问题，如下所示：

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 登陆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）。
