安裝 sklearn 時 Pip 掛起並出錯

Question

我剛買了一台新的 M1 Max MacBook Pro，我正在嘗試為它安裝一些基本的 Python 庫。 Pandas 安裝得很好，但 sklearn 掛起非常糟糕，然后給出了一個巨大的錯誤。

我試過的： pip3 install sklearn和pip install sklearn
錯誤消息長得令人難以置信。 這是最后一個看似可解析的部分：

/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
          numpy/distutils/site.cfg file (section [lapack_src]) or by setting
          the LAPACK_SRC environment variable.

正如您在底部看到的，它試圖繼續但沒有成功。

Answer 1

通過使用pip install sci-kitlearn而不是sklearn 。 對不起，可以發誓這是sklearn ！

Answer 2

我在python 3.10+ 和 3.9+版本上面臨同樣的問題

然后我切換 python 版本3.8+並且它工作正常

如果您使用 conda 那么您可以簡單地創建一個新環境

conda create -n yourenvname python=3.8

然后激活你的新環境

conda actiavate yourenvname 

然后安裝sklearn：

pip install sci-kitlearn
