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 directory
ERROR: File "setup.py" not found. Directory cannot be installed in editable mode: /content

不知道为什么我在这个库而不是其他库中出现错误。

我使用他们在其网站上建议的安装代码：

!git clone https://github.com/hyperopt/hyperopt-sklearn.git
!cd hyperopt
!pip install -e .

尽管在他们的文档中没有提到，但事实证明该软件包在PyPi上可用，并且可以简单地通过以下方式安装pip；以下是在 Google Colab 笔记本中运行的：

!pip install hpsklearn
