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.

似乎scikit学习尚未正确构建。
如果您已安装scikit“从源代码学习”,请不要忘记
要在使用包之前构建它:运行`python setup.py install`或
`在源目录中生成“”。
如果您使用过安装程序,请检查它是否适合您的需要
Python版本、操作系统和平台。
我试图进入源代码目录,输入他们说的内容,但没有用。这里有什么见解吗
谢谢!如果您为Python 2.x安装了sklearn from source,如果您没有完全删除所有sklearn文件,它的一些二进制文件可能会一直存在。Python 2.x和3.x彼此非常不兼容,因此这可能是它无法生成的原因 需要采取的几个步骤:
virtualenv-p python3 envname
pip安装-U scikit安装后学习numpy
和scipy
你是如何安装这个软件包的?你使用的是什么操作系统?@amosegellinux从外观上看(这个.so文件让我想到了这一点)。
