麻烦导入sklearn

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。它显示以下消息。谁都知道发生了什么？

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个文件且从未编译过。

如果您选中this link，则会看到scikit-learn的许多部分都是用C语言编写的。

因此，要安装此类软件包，您需要在系统中安装python-dev软件包。

python-dev包会安装许多C标头，例如python.h。

在您的系统中安装python-dev包，然后再次删除并安装scikit-learn包。
