無法在 Colab 中安裝 scikit-learn-intelex

Question

我在 Colab 中安裝scikit-learn-intelex （版本 2021.2.2）失敗。 這是我在 Colab 中所做的：

! python -m pip install --upgrade pip
! python -m pip install scikit-learn-intelex

結果得到了下面這個output，在我看來很正常。

然后，在運行以下代碼之前，我通過單擊 Colab window 橫幅的Runtime中的Restart runtime時來重新啟動 kernel：

from sklearnex import patch_sklearn

運行代碼后出現錯誤消息。 它說：

---------------------------------------------------------------------------

ModuleNotFoundError                       Traceback (most recent call last)

<ipython-input-1-45b0f2aba6d7> in <module>()
----> 1 from sklearnex import patch_sklearn

ModuleNotFoundError: No module named 'sklearnex'

NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

誰能告訴我如何在 Colab 中安裝 package？

Answer 1

這是 package 的開發人員在GitHub上回答的解決方法：

Google colab 目前運行在 Debian 系統上。 您可能在 Debian 系統上遇到的更改之一是 dist-packages 而不是 site-packages。 從 Debian 包安裝的第三方 Python 軟件進入 dist-packages，而不是 site-packages。 我們正在努力支持 Debian 系統，它應該在下一個版本中修復。 目前，我可以建議以下解決方法：

      import sys
      import os
      import site
      sys.path.append(os.path.join(os.path.dirname(site.getsitepackages()[0]), "site-packages"))

Answer 2

此問題已在 2021.4 版本中修復。 感謝舉報
