无法 pip 安装手电筒

Question

我正在尝试 pip install stanza 并收到此消息：

ERROR: No matching distribution found for torch>=1.3.0 (from stanza)

然后我运行 pip install torch 得到了以下内容（该网站不允许我包含太多代码，所以 here's the full error）

  ERROR: Command errored out with exit status 1:

DEPRECATION: Could not build wheels for torch which do not use PEP 517. pip will fall back to legacy 'setup.py install' for these. pip 21.0 will remove support for this functionality. A possible replacement is to fix the wheel build issue reported above. You can find discussion regarding this at https://github.com/pypa/pip/issues/8368.

Answer 1

我可以看到你有一台 Windows 机器，所以从 this official pytorch 网站，你可以构建最适合你的要求和系统的命令，试试这个

pip install torch===1.6.0 torchvision===0.7.0 -f https://download.pytorch.org/whl/torch_stable.html

和 here，所有 torch 软件包都位于 Windows、MacOS 和 Linux

Answer 2

我遇到了同样的错误并意识到 Pytorch 还不支持 Python 3.9。我用 Python 3.7 创建了另一个虚拟环境并且安装成功。
