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

【中文标题】无法在 PyCharm 中安装 PyTorch(Python 3.9 / macOS)【英文标题】:Unable to install PyTorch in PyCharm (Python 3.9 / macOS) 【发布时间】:2021-03-05 04:56:04 【问题描述】:

环境:

pip 版本:20.2.4 解释器:Python 3.9.0 操作系统:macOS Big Sur 其他一切都是最新的

我在终端中尝试了以下命令,但都没有成功:

点安装火炬 pip3 安装火炬 pip install torch torchvision torchaudio

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.

【问题讨论】:

这能回答你的问题吗? ModuleNotFoundError: No module named 'tools.nnwrap' 不幸的是,对于 python 版本 > 3.6,他将你引回到他们的官方网站,它要求你运行:pip install torch torchvision torchaudio 【参考方案1】:

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!

【讨论】:

而在 PyCharm 中,您可以将项目的解释器更改为 Conda 的。
