我想使用auto-sklearn。我使用了此document中的代码。所有软件包都已安装。但是我遇到了这样的错误。
!curl https://raw.githubusercontent.com/automl/auto-sklearn/master/requirements.txt | xargs -n 1 -L 1 pip install
!pip install auto-sklearn
import autosklearn.classification

我尝试了this advice，这是有关指定安装文件夹的。但是我仍然遇到相同的错误...
有人可以帮我吗？
我尝试了tidylobster和CrepeGoat解决方案，然后又收到了如下的错误消息。

答案 0 :(得分：2)
您还安装了构建软件包吗？我只是尝试按照以下步骤操作，并且工作正常。
!sudo apt-get install build-essential swig
!curl https://raw.githubusercontent.com/automl/auto-sklearn/master/requirements.txt | xargs -n 1 -L 1 pip install
!pip install auto-sklearn
import autosklearn.classification
在依赖性安装过程中正在编译一些软件包。因此，如果您没有在!curl ...之前安装build-essentials，则可能是原因。
答案 1 :(得分：1)
使用sudo apt-get来安装swig
the AutoScikitLearn instructions for Ubuntu ，
并执行 !sudo apt-get upgrade以获取所有内容的最新版本。完整：
!sudo apt-get update
!sudo apt-get install build-essential swig
!sudo apt-get upgrade
!curl https://raw.githubusercontent.com/automl/auto-sklearn/master/requirements.txt | xargs -n 1 -L 1 pip install
!pip install auto-sklearn
import autosklearn.classification
所以我重新运行了代码，发现的错误 非常 很奇怪。因为我收到的错误与@Nori所述的错误相同，但是它们在第三次尝试导入时消失了。知道这一点，编写一个肮脏的hack来解决它很容易：
!sudo apt-get install build-essential swig
!curl https://raw.githubusercontent.com/automl/auto-sklearn/master/requirements.txt | xargs -n 1 -L 1 pip install
!pip install auto-sklearn
for _ in range(3):
try:
import autosklearn.classification
break
except:
pass
else:
raise ImportError("failed to import from autosklearn")
但不幸的是，我有零想法，为什么会这样。
