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并得到以下内容

 ERROR: Command errored out with exit status 1:

   command: 'c:\python\python37\python.exe' ... ...

  ...  ...

  Traceback (most recent call last):

    ... ...

    File "C:\Users\borka\AppData\Local\Temp\pip-install-10i7vgad\torch\setup.py", line 51, in run

      from tools.nnwrap import generate_wrappers as generate_nn_wrappers

  ModuleNotFoundError: No module named 'tools.nnwrap'

  ERROR: Failed building wheel for torch

  ERROR: Failed cleaning build dir for torch

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，所以从这个官方 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在这里，所有的torch包都位于 Windows、MacOS 和 Linux 中

Answer 2

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