安装 sklearn 时 Pip 挂起并出错

Question

我刚买了一台新的 M1 Max MacBook Pro，我正在尝试为它安装一些基本的 Python 库。 Pandas 安装得很好，但 sklearn 挂起非常糟糕，然后给出了一个巨大的错误。

我试过的： pip3 install sklearn和pip install sklearn
错误消息长得令人难以置信。 这是最后一个看似可解析的部分：

/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/numpy/distutils/system_info.py:1858: UserWarning:

          Directories to search for the sources can be specified in the

          the LAPACK_SRC environment variable.

正如您在底部看到的，它试图继续但没有成功。

Answer 1

通过使用pip install sci-kitlearn而不是sklearn 。 对不起，可以发誓这是sklearn ！

Answer 2

我在python 3.10+ 和 3.9+版本上面临同样的问题

然后我切换 python 版本3.8+并且它工作正常

如果您使用 conda 那么您可以简单地创建一个新环境

conda create -n yourenvname python=3.8

然后激活你的新环境

conda actiavate yourenvname 

然后安装sklearn：

pip install sci-kitlearn
