I would like to know how to install python-poppler-qt4 on windows.I have already installed python 2.7
,pyqt4 using window installer as well as SIP. However, when I tried to install python-poppler-qt4 through pip install, error was found :
import PYQT4.pyqtconfig
ImportError:No module named pyqt.config
From what I have understand, it is because I installed the binary packages for pyqt4 rather than from the source packages so this pyqt.config.Yet if I installed it from source, it mean that I would have to make use of MSVC or MinGW 32 bits?
How do I resolve this problem? Thank you

Working on python 2.7(not anaconda). Operating system Windows server 2012 R2
The pypi installation mentions two fixes for this, installing Visual C++ redistributable 2015 and Universal C Runtime.
As well as a manual fix for older anaconda versions, which is for python3(I am not using anaconda version, and also my python version is 2.7 so presuming it doesn't apply in my case)
link here:
https://pypi.org/project/opencv-python/
installed both the dependencies but couldn't get it to work.
Any ideas on how I may fix this?
Since Python 2.7 is still supported, this could be the possible solution.
Installing OpenCV from prebuilt binaries:
Below Python packages are to be downloaded and installed to their default locations.
Python-2.7.x
Numpy
Matplotlib
Install all packages into their default locations. Python will be installed to C:/Python27/.
After installation, open Python IDLE. Enter import numpy and make sure Numpy is working fine.
Download latest OpenCV release and install it : Latest OpenCV-build
Goto opencv/build/python/2.7 folder.
Copy cv2.pyd to C:/Python27/lib/site-packeges.
Open Python IDLE and type following codes in Python terminal.
import cv2
print cv2.__version__
I downloaded scipy-0.17.0-cp27-none-win_amd64.whl and GDAL-1.11.4-cp27-none-win_amd64.whl from gohlke in C:\Python27\Scripts
To install I used
pip install scipy-0.17.0-cp27-none-win_amd64.whl
pip install GDAL-1.11.4-cp27-none-win_amd64.whl
It says the installation is complete but when I import the libraries as
import scipy
import gdal
it shows error as
No module named gdal
No module named gdal
However, I installed the matplotlib, numpy in the very same way and they are working absolutely fine.
I solved this problem eventually to found the mistake in my approach.
This problem can occur with anyone using ArcGIS in one's system.
ArcGIS comes with it's default Python package and if one installs python separately, each time the new libraries gets installed in the newer Python installation not in ArcGIS.
Therefore, the pyhton IDLE which one uses need to be from another Python installation.
Here in my case, ArcGIS has Python 2.6 and I have made an separate installation using Python 2.7.11.
All the libraries were getting installed in right place but I was opening the wrong IDLE to write scripts hence getting error.
I’m trying to run Theano on windows XP 32 with Anaconda (Python 2.7). I installed Theano following the steps provided in the Anaconda section here: http://deeplearning.net/software/theano/install_windows.html. Everything went fine but when I try to run the script import theano I get this error message:
ImportError: DLL load failed: The specified procedure could not be found. Struggling quite a bit, could anyone please help?
I had the same issue. Now I can use Theano on Windows XP 32bits with Anaconda.
With dependency walker, we found when 'import theano', the error 'ImportError' caused by LIBSTDC++6.DLL(a g++ DLL) cannot import the non-exists symbol 'vsnprintf' in 'MSVCRT.DLL'.
The key to fix this issue is, replace the mingw installed by 'conda install mingw' (rev 4.7.0). Install mingw g++ (rev 4.9.3) with 'mingw-get-setup.exe' from sourceforge instead.
Make user you PATH environment has 'C:\MinGW\bin;C:\MinGW\lib;' (default install location) to use the correct g++.
Good luck!
I have python 2.7.8 and pyscripter 2.5.3 (64 bits)installed on windows 7....Can anyone tell me which is the numpy package to download for my OS..I went through many sites and installed many numpy and python versions to work on my pyscripter resulting in only wastage of time and getting more confused by uninstalling each..I see that most of the sites give .exe (superpack) files for 32 bit.The same version and all works perfectly with 32 bit windows 8 os.. I saw .whl files for 64 on
http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
..I dont know what to do with it... I am stuck with this...
Please help.. and thanks in advance..
I made it installing numpy..All i did was to switch to 32 bit python and pyscripter .I installed python 2.7.9 version as it offers pip command so that installations will be more easy..
In Command prompt I set my path to python 27 and run
pip install numpy
I was shown with the error.."unable to find vcvarsall.bat"
and so I downloaded VCForPython27.msi from http://www.microsoft.com/en-in/download/details.aspx?id=44266
Again run the pip command and numpy will be successfully installed..!
Incase there comes an error "Could not delete multiarray.pyd :Access denied "Just close your pyscripter or probably restart and then run the pip command..Hope this helps someone..
I have developed some software using Python under Windows 7.
I have given it to a colleague to run on a Mac (OS X 10.9.2). I have never used a Mac and am having trouble helping them to get started. I have downloaded and installed Anaconda 1.9.2 on the Mac. According to the continuum documentation, libtiff is included, but when I run my python file using the Spyder IDE I get the following error when it tries to import libtiff:
ImportError: No module named libtiff.
Following one of the answers on Stack Ooverflow, I tried:
conda install libtiff
This runs and returns:
All requested packages already installed.
However on Windows 7 I can see a libtiff folder under \python27\lib\site-packages. On the Mac there is no libtiff folder under /lib/python2.7/site-packages.
Can anyone tell me what I am missing?
This question is answered here:
Installing Python modules with Anaconda or Canopy
If pip install libtiff does not work, you can download the source for PyLibTiff as directed at https://code.google.com/p/pylibtiff/source/checkout and run setup.py with whichever interpreter you would like for PyLibTiff to be installed to.
Also, you do not have to have the the C libraries that Anaconda installs installed for PyLibTiff to work if you have libtiff libraries installed elsewhere.
Unclear on this. But what you can do to begin with is to type echo $PATH from the terminal and see what paths are set. Unclear on how Anaconda interacts with the system, but a good hunch is that if the library file is not in a path then that would cause this.
Also, looking at this thread on Google Groups it seems that Anaconda installs it’s own libraries that might need to be symbolically linked into the main /usr/local/lib directory. The user Denis Engemann—who made the post—posts this bash script in the last response in the thread:
for lib in ~/anaconda/lib/*;
do
ln -s $lib /usr/local/lib/$(basename $lib);
done
I would recommend checking those two directories first before linking to make sure all is as expected.
