Hi i have installed the Scikit-learn but i keep getting error msgs when i try to import the sklearn module. it shows the following msg. anyone knows what's going on?
import sklearn

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.
As you can see in your errors: ImportError: No module named _check_build in that directory it has .c file and it never compiled.
If you check this link you will see many parts of scikit-learn has been written in C.
So for installing this kind of packages , you need to install python-dev package in your system.
python-dev package will install many C headers like python.h.
So install python-dev package in your system and then remove and install scikit-learn package again.

ImportError: libcusolver.so.8.0: cannot open shared object file: No such
file or directory
Failed to load the native TensorFlow runtime.
See https://www.tensorflow.org/install/install_sources#common_installation_problems
for some common reasons and solutions. Include the entire stack trace
above this error message when asking for help.
I have also set my environment variables like this:
export CUDA_HOME=/opt/cuda
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$CUDA_HOME/lib64:$CUDA_HOME/extras/CUPTI/lib64"
Moreover, I found that libcusolver.so.8.0 is not there, while libcusolver.so.7.5
is there in cuda/lib64/.
Somehow tensorflow is finding wrong file or I ain't know nothing.
Any help would be appreciated as I am new to all this stuff.
Python version: 2.7
OS: Linux
This may be connected to the incorrect linking of your libraries.
Simply run sudo ldconfig /usr/local/cuda/lib64. It solved for me.
If you need to know more: ldconfig man page.
I solved the issue. Actually I have cuda 7.5 installed and I was installing latest tensorflow version which probably support cuda 8.0.
So I downgraded.
pip install --upgrade \ https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.10.0-cp27-none-linux_x86_64.whl
If you installed tensorflow-gpu by using pip with prebuilt .whl, the cuda version were fixed. As far as I know, starting 0.11.0rc1, all the prebuilt packages are now built for cuda 8. So there are two ways to solve the problem:
install cuda 8 for the prebuilt packages tensorflow-gpu >= 0.11.orc1
keep cuda 7.5 stay, then build tensorflow-gpu from source code
If you are using cuda-9.0 try sudo apt install nvidia-cuda-dev (if you are using an Ubuntu distribution)
I'm using Windows-7, 64 bit PC. I want to perform spelling check for a text, using python. I tried to install PyEnchant package using "pip install pyenchant" command. It gets installed. but when I try to import enchant in ipython console, it gives error as "ImportError: cannot import name utils".
Is there any other method to install and use PyEnchant?
In [43]: import enchant
Traceback (most recent call last):
File "<ipython-input-43-be94a407aebb>", line 1, in <module>

from enchant import utils
ImportError: cannot import name utils
It looks to me like you have not got the underlying C library Enchant installed. Pyenchant is just a python wrapper for the Enchant C library. You can either build and install the C library yourself get the code from http://www.abisource.com/projects/enchant/#download or as you ask if there is another way to install it use the pyenchant-1.6.6.win32.exe link on http://pythonhosted.org/pyenchant/download.html which will install the Enchant C library for you.
I recently came across a blog(http://stronginference.com/ScipySuperpack/) on how to install sklearn . I successfully installed it and it was stored on the path:
/usr/local/lib/python2.7/site-packages/sklearn
I then went to the properties of my eclipse; under the Interpreter-Python and added the path to the PYTHONPATH. I could import sklearn but when I ran this simple code to test everything:
from sklearn import datasets
iris = datasets.load_iris()
digits = datasets.load_digits()
print digits.data
It threw the following errors:
Traceback (most recent call last):

any help on what could be wrong? I have been on these for hours now.

Try uninstalling NumPy, SciPy and scikit-learn.
Then reinstall those packages.
If you are using Windows, binaries for those packages have been provided by Christoph Gohlke, which can be quite convenient. Just download them and then use pip to install.

Pip install factory_boy seems to install the package without problems. Running pip freeze shows me:
Django==1.7
dj-database-url==0.3.0
dj-static==0.0.6
django-toolbelt==0.0.1
factory-boy==2.4.1
gunicorn==19.1.1
static3==0.5.1
However, when I edit my tests to put import factory or import factory.django... I get the result:
Traceback (most recent call last):
File "C:\Python27\lib\unittest\loader.py", line 252, in _find_tests
module = self._get_module_from_name(name)
File "C:\Python27\lib\unittest\loader.py", line 230, in _get_module_from_name
__import__(name)
File "C:\Users\Jeff\Projects\gamematch2\eventbook\tests.py", line 6, in <modul
e>
import factory.django
ImportError: No module named factory.django
I've followed the advice in:
Trouble installing factory_boy with pip
with no results.
Not sure how to proceed, any help would be appreciated.
Appears to be a problem with my virtual environment. Exiting virtualenv, installing factory_boy again, and then running manage.py test again works successfully. Not fully solved, but at least I have a work around.
I'm trying to run cython with Python2.7 installed using OSX running Mountain Lion but I get the following errors:
Traceback (most recent call last):
File "/usr/local/bin/cython", line 5, in <module>
from pkg_resources import load_entry_point
File "/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/pkg_resources.py", line 2603, in <module>

raise DistributionNotFound(req) # XXX put more info here
pkg_resources.DistributionNotFound: Cython==0.17
How can I fix this?
Thanks!
Probably what happened is that you installed cython with one version of python and are trying to run it with another. Rather than doing the standard
python setup.py build
sudo python setup.py install
Try just switching to root and both building and installing using an explicit version of python:
sudo su
/usr/bin/python setup.py build
/usr/bin/python setup.py install
(Note that this all assumes that you're installing from a source tarball).
