In a round about way, I corrupted my scipy/numpy installation on my IntelX64/Windows 7/Python 2.7 computer. I did this by trying to play around with some neural network libraries (lasagne/theano).
To fix this, I completely removed/reinstalled python 2.7.9. After that, I went to http://www.lfd.uci.edu/~gohlke/pythonlibs/ to download and install numpy and scipy with commands:
pip install C:\Users\me\Documents\numpy-1.9.2+mkl-cp27-none-win_amd64.whl
This went well and succeeded. (I can import numpy from python)
pip install C:\Users\me\Documents\scipy-0.15.1-cp27-none-win_amd64.whl
This appeared to go well too. Except the error occurs in the python console:
>>> from scipy import stats
Gives:
Traceback (most recent call last):

File "C:\Python27\lib\site-packages\scipy\special\__init__.py", line 586, in <module>
from ._ufuncs import *
ImportError: DLL load failed: The specified module could not be found.
I read up on the DLLs required and ran the 'dependency walker' (http://www.dependencywalker.com/) on "c:\python27\lib\site-packages\scipy\special_UFUNCS.PYD" and it seems there are a few DLL files not found.
libifcoremd.dll
libiomp5md.dll
libmmd.dll
msvcr90.dll
dcomp.dll
ieshims.dll
and a 6 files that look like 'api-ms-win-....dll'
From my looking around, people have solved this by reinstalling numpy, then scipy. I have tried that and the same thing occurs.
Has anyone else run into this issue and solved it?
I fixed this by a complete removal of everything (python and packages) and then installing everything again.
Just reinstalling the offending packages did not work. Neither did system restore. I will not accept this answer, because removing/installing is a work around to the real problem. I just want to post this to help anyone else in this position.
Simply install 'NumPy-1.9+MKL' from this page, it should work fine.

I am struggling to install and import python libraries into my programs. originally I was using pydev but I kept getting messages like:
Traceback (most recent call last): File "C:\Users\satur\eclipse-workspace\DMD experimental\Main.py", line 11, in <module> from matplotlib import pyplot as plot ModuleNotFoundError: No module named 'matplotlib'
I installed matplotlib using py -m pip install matplotlib which produced a few messages like this.
WARNING: The script f2py.exe is installed in 'C:\Users\satur\AppData\Local\Programs\Python\Python310\Scripts' which is not on PATH. Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location. WARNING: The scripts fonttools.exe, pyftmerge.exe, pyftsubset.exe and ttx.exe are installed in 'C:\Users\satur\AppData \Local\Programs\Python\Python310\Scripts' which is not on PATH.
I was unsure what this meant so I tried running my program again and got the module not found error again.
being unable to resolve the issue I moved over to spyder because it came with many of the libraries I wanted thus avoiding the issue. however, as soon as I tried to import and install libraries not included with spyder I encountered the module not found error and a similar warning about the path. I added the paths mentioned in the warning to the PATH in spyder now when I run my code get this error message:

I did some looking around and found this
https://github.com/spyder-ide/spyder/wiki/Working-with-packages-and-environments-in-Spyder#installing-packages-into-the-same-environment-as-spyder
I followed what instructions I understood
import sys; sys.executable
Out[50]: 'C:\\Users\\satur\\AppData\\Local\\Programs\\Spyder\\Python\\python.exe'
which is different from what I get when I run it in command prompt or in the pydev terminal both of which give me
C:\Users\satur\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\python.exe
when i go to C:\Users\satur\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\ I see: 3 versions of idel, 3 versions of pip, and 6 versions of python.
I am deeply confused. I want to install and import libraries into my python programs. I want to be able to run my programs in either (or for that matter any) ide. I seem to be hitting the very similar issues in both. every tutorial I have found online describes the steps to take to do this but not what they are or why I am doing them none of them seem to work and the more times I try to install things the more confused I get.
could someone please explain: how to install and import libraries into a python program. what python is doing when I install things and try to import them. and why both IDEs have similar but different errors.
I have a numerical simulation program that works fine at the institute I'm in, there I have a Win10 box where I installed Python 3.7.3 64-bit. I am trying to run the same program in my laptop with Manjaro and Python 3.8.1 (It was also 3.7.3 at the time I installed it, but rolling release ¬¬). The problem is that in my laptop I am getting the following error when trying to import pyFFTW
Traceback (most recent call last):
File "/home/User/Documents/Program.py", line 22, in <module>
import pyfftw # Pythonic wrapper for FFTW
File "/usr/lib/python3.8/site-packages/pyfftw/__init__.py", line 43, in <module>

ImportError: cannot import name '_fftpack' from 'scipy.fftpack' (/usr/lib/python3.8/site-packages/scipy/fftpack/__init__.py)
Process finished with exit code 1
As far as I can tell the problem is arising from the libraries within the pyFFTW package itself, but I have no idea how to fix it. I tried uninstalling and reinstalling both pyFFTW (1.17.4) and scipy (1.4.1) with little success.
I thought that I could install another version on Python in my Manjaro box and simply "match" all the versions of the packages in the Win box, but I'm looking for a less nuclear solution.
Just for completeness sake, MWE:
$ python
>>> import pyfftw
This is fixed in master. A release should be made shortly. You can either wait for that or pull from github.
Edit: Release made that fixes this on Feb 3 2020.
Currently I am using Python 3.7, and Ubuntu 18.04. I downloaded wxPython from pip, but when I tried to import wx in my terminal, I get this error:
>>> import wx
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/aleejandrof/anaconda3/lib/python3.7/site-packages/wx/__init__.py", line 17, in <module>
later on, when I tried other ways like and "._core import" I received an error like this:
ImportError: /home/aleejandrof/anaconda3/bin/../lib/libpangoft2-1.0.so.0: undefined symbol: pango_font_description_set_variations
After reading some posts here, I tried deleting the wx.py and wx.pyc files, which didn't work. The same happened when I read that downloading the main excecutable file would make the import occur with no errors, but it popped the same errors.
AttributeError: module 'wx' has no attribute '__version__'
I am trying to run a GUI pipeline, which works with wxPython. I'm thankful in advance, if any of you has suggestions.
When I made an environment of ubuntu18.04 using docker, ran into the same problem.
I had multiple libpangoft2-1.0.so.0 files.
It seemed the problem was /opt/conda/lib/libpangoft2-1.0.so.0 was looked up.
To change the name of the file solved the problem.
find / -name libpangoft2-1.0.so.0
/opt/conda/lib/libpangoft2-1.0.so.0
/opt/conda/pkgs/pango-1.42.4-h049681c_0/lib/libpangoft2-1.0.so.0
/usr/lib/x86_64-linux-gnu/libpangoft2-1.0.so.0
mv /opt/conda/lib/libpangoft2-1.0.so.0 /opt/conda/lib/libpangoft2-1.0.so.0-void
You may want to try:
conda install -c asmeurer pango
I am trying to import the spherical harmonic toolbox (SHTOOLS) in python. I have the files downloaded and unzipped and am using RedHat.
I added the package's path to my python system path and when I go to import the package, I get this error:
>>import pyshtools
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "pyshtools/__init__.py", line 49, in <module>
load_documentation()
File "pyshtools/__init__.py", line 27, in load_documentation
from . import _SHTOOLS
ImportError: cannot import name _SHTOOLS
I can not seem to figure out what the issue is. I checked that the path to this folder was actually added to the system path and it was.
Is this an issue on my end? Or is it possible that I have something downloaded incorrectly? If so, how would I go about fixing this issue?
The SHTOOLS package needs to be built with make first to compile the Fortran libraries. The wiki on Github gives directions on which libraries are required - libblas-dev, liblapack-dev, g++, gfortran, and libfftw3-dev (these are the Ubuntu packages, they may have slightly different names on Redhat). Once these are installed, you need to run make, then sudo make all to install the Fortran and Python components. The Makefile has a lot of good comments in it, I'd recommend reading through it before running make.
I need to install the Python module audiolab for a research project, and while I have managed to install it and get the module to import in the Python shell, it returns an error in calling one of the most basic functions in the module, wavread().
I am using Python2.7.1 mainly, though I did try backtracking and installing audiolab for Python2.6.6, only to find the same error message after importing and calling the wavread() function.
My operating system is Mac OS X 10.5.8 with an intel processor.
This is generally how it goes:
import numpy
import scipy
import scikits.audiolab as audio
x, fs, nbits = audio.wavread('test.wav')
Traceback (most recent call last):
File "<pyshell#3>", line 1, in <module>
x, fs, nbits = audio.wavread('test.wav')
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/scikits.audiolab-0.11.0-py2.7-macosx-10.3- fat.egg/scikits/audiolab/pysndfile/matapi.py", line 91, in basic_reader
hdl = Sndfile(filename, 'r')
File "_sndfile.pyx", line 488, in scikits.audiolab.pysndfile._sndfile.Sndfile.__init__ (scikits/audiolab/pysndfile/_sndfile.c:4251)
IOError: error while opening test.wav
->error while opening file test.wav
-> System error : No such file or directory.
I installed the libsndfile library (which I believe audiofile is simply a wrapper around) using pip and that seemed to install fine without error. I then tried to install audiolab from the tar.gz file, using the command python setup.py install in Terminal. This is as directed in the documentation, found here under the header 'build'
The documentation also talks about in some cases needing to make a 'site.cfg' file, which from what I saw after some google searching, only really applies to Windows users, though I'm not certain about this.
Any light you could shed on my problem would be much appreciated!!
The audiolab documentation is somewhat lacking, but wavread() requires an input file. In your code, that input is test.wav. If it doesn't exist in the working directory (usually the location of your python script), you need to provide the full path to the file.
