sklearn不在那里，但它在/usr/local/lib/python2.7/dist-packages

Question

在我公司的服务器上，我尝试运行Python脚本。然而它告诉我sklearn丢失了，但它在/usr/local/lib/python2.7/dist-packages

中是最新的

:~/Eclipse-Stats$ python Main.py
2017-07-24 14:01:55.852751
Traceback (most recent call last):
  File "Main.py", line 2, in <module>
    import kmeans
  File "/home/ubuntu/Eclipse-Stats/kmeans.py", line 3, in <module>
    import sklearn
ImportError: No module named sklearn
:~/Eclipse-Stats$ pip install -U scikit-learn
Requirement already up-to-date: scikit-learn in /usr/local/lib/python2.7/dist-packages

也许它认为它不在服务器上，但是当我尝试安装它时，它会将它安装在已经拥有它的笔记本电脑上？

我在服务器上安装了Python 2.7.13。这似乎是问题，因为当我运行wiyt python3它似乎工作：

 ~/Eclipse-Stats$ python3 Main.py
  File "Main.py", line 113
    print "list of groups you can recommend : "
                                              ^
SyntaxError: Missing parentheses in call to 'print'

来自Python解释器

但是该网站的西班牙语版本（FJSevilla）的Python专家告诉我它不确定。

我试图从python解释器导入它：

>>> import sklearn
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

ImportError: No module named sklearn

所以我尝试卸载，清除并重新安装它（我不记得在提示时我想到的地方）：

卸载并重新安装

sudo apt-get install build-essential python-dev python-setuptools python-numpy python-scipy libatlas-dev libatlas3-base
...
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

然后我尝试再次导入它但失败了：

>>> import kmeans
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "kmeans.py", line 3, in <module>
    import sklearn
ImportError: No module named sklearn
>>> kmeans.__file__
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'kmeans' is not defined

并且：

>>>sudo pip install -U scikit-learn

>>> import sklearn
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named sklearn

许可问题？

我最近的尝试是根据this answer from boshea in 2013

授予权限问题

ubuntu@ip-172-31-41-89:~/Eclipse-Stats$ sudo chmod -R go+rX /usr/local/lib/python2.7/dist-packages
ubuntu@ip-172-31-41-89:~/Eclipse-Stats$ python

在系统级

FJSevilla建议查看是否已在系统级安装了sklearn：

pip install --user --install-option="--prefix=" -U scikit-learn
/home/ubuntu/.local/lib/python2.7/site-packages/pip/commands/install.py:194: UserWarning: Disabling all use of wheels due to the use of --build-options / --global-options / --install-options.
  cmdoptions.check_install_build_global(options)
Requirement already up-to-date: scikit-learn in /usr/local/lib/python2.7/dist-packages

无论如何......

$ ls /usr/local/lib/python2.7/dist-packages/sklearn
__check_build              exceptions.pyc            multiclass.py

_build_utils               feature_selection         multioutput.pyc

base.pyc                   grid_search.pyc           neighbors

似乎安装没问题但是翻译没有查看正确的文件夹...
