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: Command errored out with exit status 1:   command: 'c:\python\python37\python.exe' ... ...       cwd: C:\Users\borka\AppData\Local\Temp\pip-install-10i7vgad\torch  Complete output (2 lines):  running clean  error: [Errno 2] No such file or directory: '.gitignore'  ----------------------------------------  ERROR: Failed cleaning build dir for torchDEPRECATION: 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.

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。
