I am basically looking for a faster alternative to scipy.fftpack.fft and found pyFFTW.
However, I am about to despair since no matter what I am trying I am not getting pyFFTW to work.
What I did so far:
installed pyFFTW by means of PIP: pip install pyfftw
downloaded FFTW 3.3.5 for Windows from here
extracted the zip file and copied anything to the site-package directory of pyFFTW
As soon as I try to import pyFFTW, the following exception occurs:
Python 2.7.8 (default, Jun 30 2014, 16:03:49) [MSC v.1500 32 bit (Intel)]
on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyfftw
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Program Files (x86)\Python27\lib\site-packages\pyfftw\__init__.py", line 16, in <module> from .pyfftw import (
File "__init__.pxd", line 861, in init pyfftw.pyfftw (C:\projects
\pyfftw\pyfftw\pyfftw.c:17297)
ValueError: numpy.ufunc has the wrong size, try recompiling. Expected 104, got 112
I am using numpy 1.7.1.
Any suggestions about how to fix this problem are highly appreciated.
BTW: I already tried to uninstall / install numpy and pyFFTW several times.
You need to upgrade numpy. Whatever binary you found was compiled against a too-new copy of numpy.

On a fresh install of Raspbian 10 on Raspberry PI 3 B+, I am trying to install with Python 3.7 the numpy==1.19.5. The problem is that when I import pandas, I get this error:

If I keep the default installation of numpy==1.20.2, it works perfectly, but I have a requirement for any numpy version less than 1.20. I've tried some versions of pandas, but nothing works. I've hit a dead-end so I am asking here for help.
Any new solution for this. I am unable to from ciscoconfparse import CiscoConfParse
I tried several versions of ciscoconfparse in python3 usin gpowershell in windows10.

I still have not found a version that will let me import the module.
I browsed through several links here..but did not find an answer. The closest issue to mine is:
ciscoconfparse in Python 3.4 module doesn't import correctly
but not answer.
Any new info?
Thanks
I have reproduced the bug where Win10 and Python 3.7.0 cause problems.
FWIW, if you completely uninstall Python 3.7.0 (including manually deleting your Windows installation directory tree), then install Python 3.7.1, you should not have this problem with Windows 10.
I installed Python 3.6.1. And then installed pybrain using git (See Screen Shot). Then when I useimport pybrainit works but afterwards when I usefrom pybrain.tools.shortcuts import buildNetworkit gives me error that: Python 3.6.1 (v3.6.1:69c0db5, Mar 21 2017, 17:54:52) [MSC v.1900 32 bit (Intel)] on win32

Why is it doing like this? Kindly help me out here. Thanks
EDIT: Excluded screen shots. Added everything in post as per request.
except ImportError, e is Python 2 syntax and you've tried to run the code with Python 3. Install the latest version — the code seems to be fixed in git (it's except ImportError as e now, so it's suitable for both Python 2.7 and Python 3).
Just an update: I was able to resolve the issue by un-installing python, then installing python 3.6.2 (64 bit), using pip3 (pip3 install pybrain) I was able to install the latest version of pybrain which worked flawlessly. Thanks to everyone who tried to help me out when I was fairly new to python. Love this community!!
I want to install paramiko on win 7 32bit ,the python is 3.3 .

Paramiko does not run on Python 3. Yet. I'm working on a development branch (https://github.com/dorianpula/paramiko/tree/python3-support) to add support for Python 3, and I'm working on fixing this particular issue.

In [2]: import numpy
To make stuff even more complicated, in another Eclipse workspace, this import works fine. Restarting eclipse didn't help. I also tried to re-config the interpreter in Preferences->python->interpreter->python (as in this question), but the problem still exists
Two additional similar problems were described on SO (this and this), but both of them were observed with IronPython and I couldn't find anything I could use in the few answers that were provided.
EDIT As suggested by dutt, I checked Preferences->Pydev->Interpreter python->libraries in both the tested workspaces (the working one and the one that doesn't). The malfunctioning workspace contained the following library in system libs C:\Python26\lib\site-packages\numpy-1.5.0-py2.6-win32.egg . On the other hand, the working workspace doesn't list any numpy library in its system libraries list. I have removed the above library from the list in the not working workspace.
(Assuming you'r using PyDev) Look in Preferences->Pydev->Interpreter-Python->Libaries, you may have to add NumPy there. Should be located in your python/lib/site-packages folder.
check the version of your python release and numpy release. they should be the same.
It happened to me and I solved it re-installing my python and numpy for win32, although I have a 64-bit machine.
