I am using python in an anaconda environment. When I import matplotlib I am getting compatibility issues with xwpython. So, I would like to switch the backend. Usually, that would be done with a matplotlibrc file. However, it seems that matplotlibrc under ~/.config/matplotlib/ is ignored. Is it possible to check whether and which matplotlibrc file was used during import of matplotlib? Using python 2.7.
You can get the file path using:
import matplotlib
print(matplotlib.matplotlib_fname())
Which in my case returns:
'/Users/m300241/.matplotlib/matplotlibrc'

I'm trying to run a code in python2.7 on windows os that uses sentiment analysis
from vaderSentiment.vaderSentiment import SentimentIntensityAnalyzer
analyzer = SentimentIntensityAnalyzer()
and I'm getting this error
ImportError: No module named vaderSentiment
Can anyone help me with this?
Assuming you solved this one as it's from 7 months ago, but for anyone else searching for it:
Go into terminal/cmd and paste the following:
pip install vaderSentiment
More info on VADER: https://github.com/cjhutto/vaderSentiment
from vaderSentiment.vaderSentiment import SentimentIntensityAnalyzer
#note: depending on how you installed (e.g., using source code download versus pip install), you may need to import like this:
#from vaderSentiment import SentimentIntensityAnalyzer
read the comment in a code
Try running your file with Python3 instead of just python. Sometimes when you have different pips/pythons installed on your computer you might have vaderSentiment installed in python2 when you need to run it in python3.
new in python.
I have python 2.7.
I just installed a new module (beatifulsoup) from cmd in windows 7 which is correctly installed : When I enter the python consol from the cmd I can import succesfully bs4 without error.
My problem is that I cannot import it when I am using Aptana studio. Or if I code it in sublimetext and save it as a py file, when I run it I get the error message "cannot import name beautifulsoup 4". I don't get why? Is it a problem of pydev environment on aptana? If yes how can I add modules to Aptana and sublimetext3 ?
Are you trying to import like this:
from bs4 import BeautifulSoup
If not, try it that way. Hope this helps!
(Perhaps you should add your import statement to the question so we can see if there is a problem with the statement or if the issue resides somewhere else)
I have written codes but it's showing cannot import pygame module
Download pygame from here: http://www.pygame.org/download.shtml
If you are not sure which version of python you are running, execute the following code in your shell:
import sysconfig
version = sysconfig.get_python_version()
print(version) #Python3
print version #Python2
Usually, Python3 will also accept the print command without brackets, so using sysconfig is the safest way. Sysconfig will also tell you which minor version you are using (such as 3.4.5)
Once you have download pygame, tryimport pygame in your shell. If this does not work, type help('modules'). This will now list all your modules. If pygame is not in there, check in which folder all other modules are saved and move the pygame module to that file path.
You can also use sysconfig to display all the file paths python is using:
import sysconfig
paths = sysconfig.get_paths()
print(paths) #For Python2, see print method above
I don't quite understand what you mean with "And make games", but the pygame website has a great documentary and some example codes to help you learn progamming with the pygame module.
Hope I could help,

I would like to have a script invoke numpy from a c++ embedded python runtime by setting the runtime path to know about the numpy module located within site-packages.
However I get the error:
cannot import name 'multiarray'
from \Lib\site-packages\numpy\core__init_.py on the line
from . import multiarrray
I have tried to set the os.path to be xxx\numpy\core but it still cannot seem to find the multiarray.pyd file during the import statement
I have read through similar questions posed but none of the answers seem relevant to my case.
I am using Python 3.4.4 (32 bit) and have installed Numpy 1.11.1 using the wheel
numpy-1.11.1-cp34-none-win32.whl
python -m pip install numpy-1.11.1-cp34-none-win32.whl
Completed without any errors.
Seems like the failure message maybe more general than just an incomplete PYTHONPATH?
Also think it might be broader than Numpy in that ANY .pyd based package that is imported from the embedded environment will have this problem?
Any help appreciated.
Did you ensure all your NumPy includes: \numpy\core\include\numpy\ were present during the build? That's the only time I get those types of errors was if the build couldn't find all the NumPy includes... although during embedding I found that the numpy entire directory (already built on your build machine) has to be inside a directory under Py_SetPath(python35.lib;importlibs); assuming importlibs is a directory with NumPy inside and anything else you want to bundle.
Seems like the answer was to install python 3.4.1 to match the python34.dll version of 3.4.1.
Everything works as supposed to on the Django development server. In Apache, the django app also works except when matplotlib is used. Here's the error I get:
No module named multiarray.
Exception Type: ImportError
Exception Value: No module named multiarray
Exception Location: /usr/share/pyshared/numpy/core/numerictypes.py in <module>, line 81
Python Executable: /usr/bin/python
Python Version: 2.6.4
From the python shell, both statements work: import numpy.core.multiarray and import multiarray. Any ideas?
Thanks
As I'm looking over the numpy files, I found the multiarray module, which has an extension of 'so'. My guess, is that mod_python is not reading these files.
Problem solved. Here's what I did.
First of all, before I was getting the import error:
"No module named multiarray."
I was getting an error like this:
": Failed to create /some/dir/.matplotlib; consider setting MPLCONFIGDIR to a writable directory for matplotlib configuration data"
By adding the pyshared folder to the PythonPath variable, this error went away and I got the import error.
So here's how I fixed it:
Removed the pyshared folder from the PythonPath variable.
Before importing the matplotlib module, add these lines:
import os
os.environ['HOME']='/some/writable/dir'
Next, before import matplotlib.pyplot or pylab, add these lines:
import matplotlib
matplotlib.use('Agg')
# 'Agg' or whatever your backend is.
This is documented here.
That's is! It's working on python2.5 for me now. But I believe it'll work on 2.6 as well.
On Win32 I solved a similar problem (not being able to load pyd modules through ISAPI_WSGI (IIS)) by downgrading from py2.6.5 to py2.5. It seems like this might be a Python bug that has been re-introduced. See for example this discussion.
