导入sklearn的麻烦

Question

您好，我已经安装了 Scikit-learn，但是当我尝试导入 sklearn 模块时，我不断收到错误消息。它显示以下味精。有谁知道发生了什么？

import sklearn
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "sklearn/__init__.py", line 31, in <module>
    from . import __check_build
  File "sklearn/__check_build/__init__.py", line 46, in <module>
    raise_build_error(e)
  File "sklearn/__check_build/__init__.py", line 41, in raise_build_error
    %s""" % (e, local_dir, ''.join(dir_content).strip(), msg))
ImportError: No module named _check_build

It seems that scikit-learn has not been built correctly.

If you have installed scikit-learn from source, please do not forget
to build the package before using it: run `python setup.py install` or
`make` in the source directory.

If you have used an installer, please check that it is suited for your
Python version, your operating system and your platform.

正如您在错误中看到的那样：ImportError: No module named _check_build 在该目录中它有 .c 文件并且它从未编译过。

如果您检查this link，您会看到scikit-learn 的许多部分是用C 编写的。

所以要安装这种包，你需要在你的系统中安装python-dev包。

python-dev 包将安装许多 C 头文件，例如 python.h。

所以在您的系统中安装python-dev 包，然后删除并再次安装scikit-learn 包。
