I am using the windows command prompt to install the scikit learn library using the command pip install -U scikit-learn. However, whenever I try to import it into my program I get an error stating that there is no module named 'sklearn'. Also, whenever I download the library using pip, for some reason, my pip package installer seems to break and pip is no longer recognized as a command on my cmd. I have numerous other modules which work perfectly fine so I don't see a reason as to why I can't get this specific library to work. I am still quite new to this kind of thing, so maybe I am missing something.

Try to upgrade pip to newest version by python -m pip install --upgrade pip considering you are still using Windows. And then try to download sciKitLearn by pip install sklearn
This is how I had solved my problem but keep note that it was about a year ago
If all this doesn't work, try VirtualEnv.
I don't know much about python and I need help to install a python software.
I am using linux mint 12.8.
Since I have tried many things I think I have several versions of python installed (3.5 and 3.7 I think...).
When I run setup.py install I get:
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/CommandNotFound/CommandNotFound.py", line 7, in <module>
import dbm.gnu as gdbm
File "/home/zach/10_Soft/anaconda3/lib/python3.7/dbm/gnu.py", line 3, in <module>
from _gdbm import *
ModuleNotFoundError: No module named '_gdbm'
I tried to install python3.5-gdbm (which appears to be up to date) and python3.7-gdbm (which is not found).
They both seem to be virtual packages of the same package python3-gdbm. I don't really know what to do with this information however...
Do you know what I should do?
I was able to solve this issue using this command:
sudo cp /usr/lib/python3.5/lib-dynload/_gdbm.cpython-35m-x86_64-linux-gnu.so /usr/lib/python3.7/lib-dynload/_gdbm.cpython-37m-x86_64-linux-gnu.so
So I was able to install sklearn for python2 but for some reason I having issues with doing the same for python3. I am getting this error:

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.
I tried to go into the source directory and type in what they say to no avail. Any insight here?
Thanks!
If you installed sklearn from source for Python 2.x, some of its binaries may have persisted if you didn't fully remove all sklearn files. Python 2.x and 3.x are quite incompatible with each other, so this might be a reason why it's failing to build.
A few steps to take:
Consider using a virtualenv for your sklearn projects, especially if you have a lot of different packages or Python versions floating around. It's great for keeping different development environments with different Python packages and libraries isolated. Follow this guide if you don't have it already. When creating your virtualenv, make sure to install it with Python 3.x by using this command when creating your virtualenv:
virtualenv -p python3 envname
If building from source: Redownload the sklearn source for your Python 3 version and place it in your virtualenv. Closely follow all build instructions. That should hopefully give you a clean install of sklearn.
If installing with pip: Activate your virtualenv, then:
pip install -U scikit-learn after installing numpy and scipy.
I have developped a tool under python 2.5 and can't upgrade to a newer python version as I need to use an API developped under python 2.5 as well.
I recently tried my tool under another machine and it seems it hasn't wx module installed as you can see below:
>>> import wx
Traceback (most recent call last):
File "<interactive input>", line 1, in <module>
ImportError: No module named wx
So I searched for the wxpython source. However once I tried to install the source with:
D:\tmp\wxPython-4.0.0b2>c:\Python25\python.exe setup.py install
I got following error:
Traceback (most recent call last): File "setup.py", line 15, in
from setuptools import setup, find_packages ImportError: No module named setuptools
I can't either install whl files as I don't have pip.
So, how can I install wxpython for python 2.5 under Windows?
Is there any executable there in the web that I couldn't find? May there be a workaround by copying the wx module from a python directory from another computer?
As I had to install wxpython 2.7.2.0 I finally got it from wxPython2.7-win32-ansi-2.7.2.0-py25.exe.
As stated in Patrick's comment all wxpython executables for any version are under https://sourceforge.net/projects/wxpython/files/wxPython/
I'm trying to call a function from the cluster module, like so:
import sklearn
db = sklearn.cluster.DBSCAN()
and I get the following error:
AttributeError: 'module' object has no attribute 'cluster'
Tab-completing in IPython, I seem to have access to the base, clone, externals, re, setup_module, sys, and warning modules. Nothing else, though others (including cluster) are in the sklearn directory.
Following pbu's advice below and using
from sklearn import cluster
I get:

I'm using Python 3.4 on Windows, scikit-learn 0.16.1.
You probably don't use Numpy+MKL, but only Numpy.
I had the same problem and reinstalling Numpy with MKL
pip install --upgrade --force-reinstall "numpy‑1.16.3+mkl‑cp37‑cp37m‑win32.whl"
fixed it.
Note: update the file to the latest version, possibly 64bit - see the list of available Windows binaries
Problem was with scipy/numpy install. I'd been using the (normally excellent!) unofficial installers from http://www.lfd.uci.edu/~gohlke/pythonlibs/. Uninstall/re-install from there made no difference, but installing with the official installers (linked from http://www.scipy.org/install.html) did the trick.
I am using anaconda got the same error as the OP, when loading Orange, or PlotNine.
I can't recall when this start to happen.
Tracing the dependency of Anaconda3\Lib\site-packages\scipy\special\_ufuncs.cp36-win32.pyd, libifcoremd.dll and libmmd.dll are missing in DependencyWalk. Searching them in anaconda root directry, they are located in both ICC_RT and one version of MKL package.
Adding Anaconda3\pkgs\mkl-2017.0.3-0\Library\bin to PATH, seems to fix SciPy and NumPy related DLL load failure, the above package starts to work again.
I still don't know how to fix this properly. Apparently the downside is that the MKL package could be updated and versions may change so does the path. In this aspect Its equally inconvenient as adding a non-managed package.
Reinstalling ICC_RT fixed the issue for me, libmmd.dll and the related dlls are automatically copied into anaconda3/library/bin afterwards, which is automatically added into PATH by activate command. All previous numpy/scipy related cant load DLL errors are gone now.
From the error log, it shows that scipy module is the most recent module fails to import
File "C:\Python34\lib\site-packages\sklearn\utils\fixes.py", line 318, in <module>

from . import _iterative
ImportError: DLL load failed: The specified module could not be found.
I have the same error that show the same log, the problem'd gone when I uninstall/install scipy:
pip uninstall scipy
pip install scipy
Place this line on top of the python file
from sklearn import cluster
That should do it :))
For me what fixed it were these commands:
pip uninstall sklearn
pip uninstall scikit-learn
pip uninstall scipy
pip install scipy
pip install scikit-learnhere
I had the same issue and solved it by installing/updating the mkl package:
conda install mkl
or
pip install mkl
Just for full information, this also downgraded the following packages:
The following packages will be UPDATED:
mkl: 2017.0.4-h6d528fc_0 defaults --> 2018.0.3-1 defaults
The following packages will be DOWNGRADED:
numpy: 1.11.3-py34_0 defaults --> 1.10.1-py34_0 defaults
pandas: 0.19.2-np111py34_1 defaults --> 0.18.1-np110py34_0 defaults
scikit-learn: 0.18.1-np111py34_1 defaults --> 0.17-np110py34_1 defaults
scipy: 0.19.1-np111py34_0 defaults --> 0.16.0-np110py34_0 defaults
I struggled trying to figure this one out; tried to download and install the (unofficial) Numpy+MKL library from the website (risky/tedious?).
Ultimately found success by:
Login to command prompt using admin rights; how to here: https://superuser.com/questions/968214/open-cmd-as-admin-with-windowsr-shortcut
Uninstall existing/tangled version of Scipy & Numpy
pip uninstall scipy
pip uninstall numpy
Fresh install Scipy & Numpy
pip install scipy
pip install numpy
Run Jupyter notebook; it worked for me.
The message ImportError: DLL load failed: The specified module could not be found
informs that there is failure to identify and source the required DLL(s) to use the scikit-learn library; a fresh install of scipy/numpy probably enables a better routing of DLL connections called from Jupyter notebook code(s).
download microsoft visual c++ distribution
link : https://www.microsoft.com/en-in/download/details.aspx?id=53840
vc_redist.x64.exe
install and run this .exe file in your computer.. the DLL import module error will not appear after this
now it will work fine enjoy :)
