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.

I am trying to import win32api in python 2.7.9. i did the "pip install pypiwin32" and made sure all the files were intalled correctly (i have the win32api.pyd under ${PYTHON_HOME}\Lib\site-packages\win32). i also tried coping the files from C:\Python27\Lib\site-packages\pywin32_system32 to C:\Python27\Lib\site-packages\win32. I also tried restarting my pc after each of these steps but nothing seems to work! i still get the error 'No module named 'win32api''
Well, turns out the answer is upgrading my python to 3.6.
python 2.7 seems to old to work with outside imports (I'm just guessing here, because its not the first time I'm having an import problem)
hope it helps :)
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.
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'
New to python; running windows. I am using python27, and ran the following code. It failed, even though it recognized numpy. Then, I made sure that numpy was installed by running pip install numpy. Reran the code and had the same problem: numpy was recognized, and a list of classes in the auto-suggest populates, but not numpy.matrix. I can't seem to find any indication that this should be a problem. It seems to just work...
import numpy
board = numpy.matrix([0,0,0,0,0],[0,0,0,0,0],[0,0,0,0,0],[0,0,0,0,0],[0,0,0,0,0])
It compiles, but the numpy.matrix still has a red line under it. the popup message when I mouse over it says: undefined variable from import: matrix
How do I enable the matrix class?
Or am I dealing with a Liclipse error? (Liclipse is my IDE)
Numpy is getting imported from:
module 'numpy' from 'C:\Python27\lib\site-packages\numpy\__init__.pyc'
I'm working on converting a simple GUI script written with Python 2.7 and Pyqt4 into a standalone executable using py2exe. I keep getting "no such file exists" errors, and I've managed to fix a few, though this one seems stubborn. It can't find msvcp90.dll, and returns an error message with a short traceback to distutils and then back to my py2exe script, which isn't very enlightening.
I've installed the MS C++ redistributable runtime, as recommended in
py2exe fails to generate an executable
but my script still can't locate the .dll. Below is my py2exe script, with the name of my script blocked out:
from distutils.core import setup
from py2exe.build_exe import py2exe
import sys, os, zmq
sys.argv.append('py2exe')
os.environ["PATH"] = \
os.environ["PATH"] + \
os.path.pathsep + os.path.split(zmq.__file__)[0]
setup(
options = {'py2exe':{'bundle_files':1,"includes":["zmq.utils",
"zmq.utils.jsonapi","zmq.utils.strtypes"]}},
console = [{'script':"#######.py"}],
zipfile = None
)
I've already fixed an issue with zmq (which isn't ever used by my script, or my GUI, for that matter, as far as I know). What am I doing wrong?
Right, I've managed to get my app to build, and although the question is now moderately old, it's my hope this is eventually of use to someone.
Firstly, py2exe is probably the wrong tool. It's old and AFAICT unmaintained. Consider PyInstaller instead. Using PyInstaller is literally as simple as installing it, installing PyWin32, and then going python %path_to_pyinstaller%/pyinstaller.py --onefile --windowed source.py. PyInstaller deals with all the mess of side by side assemblies and so on without you having to do anything.
In short, use PyInstaller.
However, to answer your question, this worked for me:
The question you've linked to - in particular this answer is the right start. Find the right DLLs and copy them to C:\Python27\DLLs
Ditch your existing setup.py file. If you're not using zmq, there's no reason to import it. Also, for a windowed application you want windows= not console=. My file goes (for packaging show.py):
#!/usr/bin/python
from distutils.core import setup
import py2exe
setup(options={'py2exe':{'bundle_files':1}},
windows=['show.py'])
