python - 无法在 PyCharm 中安装 PyTorch（Python 3.9 / macOS）

问题描述

环境：

我在终端中尝试了以下命令，但都没有奏效：

我收到每个命令的不同错误消息，但这是“pip install torch”的输出：

Collecting torch
  Using cached torch-0.1.2.post2.tar.gz (128 kB)
Requirement already satisfied: pyyaml in /Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages (from torch) (5.3.1)
Using legacy 'setup.py install' for torch, since package 'wheel' is not installed.
Installing collected packages: torch
    Running setup.py install for torch: started
    Running setup.py install for torch: finished with status 'error'

DEPRECATION: The -b/--build/--build-dir/--build-directory option is deprecated. pip 20.3 will remove support for this functionality. A possible replacement is use the TMPDIR/TEMP/TMP environment variable, possibly combined with --no-clean. You can find discussion regarding this at https://github.com/pypa/pip/issues/8333.

解决方案

好的，我通过使用 conda 包管理器而不是 pip 解决了这个问题。Conda 使用 python 3.8.5 版本，而 3.9 版本用于我的 pip 管理器。我不太确定不兼容问题是由于 pip 本身，还是由于它使用的是 python 3.9 版。无论如何下载图形 macOS 安装程序后：

conda install pytorch torchvision torchaudio -c pytorch

这应该会成功安装 PyTorch！
