如何在 Google Collab 中安装 HyperOpt-Sklearn 库？

Question

每次我尝试在 Google Collab 中安装 HyperOpt-Sklearn 库时，都会收到以下错误：fatal: destination path 'hyperopt-sklearn' already exists and is not an empty directory./bin/bash: line 0: cd: hyperopt: No such file or directoryERROR: File "setup.py" not found. Directory cannot be installed in editable mode: /content不知道为什么我在这个库中遇到错误，而在其他库中却没有。我使用他们在网站上建议的安装代码：!git clone https://github.com/hyperopt/hyperopt-sklearn.git!cd hyperopt!pip install -e .

尽管他们的文档中没有提及，但事实证明该软件包在PyPi上可用，并且可以通过简单地安装pip；以下是在 Google Colab 笔记本中运行的：

!pip install hpsklearn
