I just installed Enthought Canopy on an Imac Os 10.6.8.
I get an error message (appended below) when I try to test sklearn.
The error is ImportError: numpy.core.multiarray failed to import.
It looks like the wrong version of numpy is being used. I'm not sure how to fix.

ImportError: numpy.core.multiarray failed to import
I discovered that I had in my PYTHONPATH (as defined in my .profile)
/Library/Python/2.6/site-packages from where the wrong version of numpy was being picked up.
Eliminating this corrected the problem.

I've installed what I believe to be a matching pycuda from this file:
pycuda-2021.1+cuda115-cp38-cp38-win_amd64.whl
This simple example fails
import pycuda.driver as drv
drv.init()
print("Detected {} CUDA devices".format(drv.Device.count()))
With this error:

NVCC is in my path
Adding os.add_dll_directory(os.path.join(os.environ['CUDA_PATH'], 'bin')) has no effect

Any ideas on how to get past this? I've searched and tried several solutions.
It is quite strange, but updating the Nvidia display driver fixed the issue for me.
But in my case there was no issue on my PC with the same versions of Windows, Python, CUDA and PyCuda. The issue appeared on the different Windows 10 machine, when launching the exe, packaged by PyInstaller. So, updating the display driver was the fix for this machine.
Does anyone know how to undo the changes to paths and permissions wrought by upgrading to El Capitan. Specifically, it appears that OS X is now using the system python instead of my Canopy installation.
These look ok:

But trying to launch ipython fails:

A complete update of my installed Canopy packages including ipython seems to have fixed the problem.
When importing scipy:

I am running Eclipse on windows 7. I installed scipy successfully using
pip3.4 install "scipy-0.16.0rc1-cp34-none-win32.whl"
Can you tell me how I can get scipy to work with this simple program on Windows 7?
As mentioned prior, the easiest way to get SciPy running on windows is to simply download the Anaconda distribution. Be sure to obtain the version you want. It works out of the box. Plus you get Jupyter/IPython Notebook which is a really cool interactive GUI interface. It's almost like working in Matlab!

A similar question was asked before by someone else: https://stackoverflow.com/questions/23600028/py2app-app-crashes-on-earlier-mac-os-x-versions
I have an app that runs fine on my machine (OSX 10.9.4), but when I move it to another machine running 10.7.5, the app crashes on start up. I get the following messages in console:

Earlier, to get around this error, I just uninstalled pillow. I'm not sure why pillow libraries were being added to the app to begin with, since I didn't think I was using it. But now, when attempting this workaround, I get another error:
Traceback (most recent call last):

Apparently I'm using PIL now somehow. My script imports the following:
from __future__ import division
import easygui as eg
import os, zlib, re, datetime, getpass, tkMessageBox, sys
import zipfile as z
import Tkinter as tk
from tkFileDialog import askdirectory
from optparse import OptionParser
Here's my setup.py:
from setuptools import setup
APP = ['zipperscript.py']
DATA_FILES = []
OPTIONS = {'argv_emulation': True, 'excludes': ['']}
setup(
app=APP,
name="Zipperscript_HI_50",
data_files=DATA_FILES,
options={'py2app': OPTIONS},
setup_requires=['py2app'],
version="Hawaii branch 4.0.50"
)
I'm not sure that the OS version is causing the problem, but that's my theory right now. I'm not sure how to proceed. Any help or suggestions are greatly appreciated.
I encountered a similar problem while using buildout on Mac OS 10.8.5. It seems that the pre-compiled packages available on Pypi have been compiled on newer versions of OS X and unfortunately insufficiently tested on older versions.
The solution is to install pillow from source instead. Download the source, and run pip install your_downloaded_file. You may need to install dependencies such as libjpeg and zlib beforehand.
After doing this I do not encounter the errors anymore and have pillow version 5.4.0 installed.
After some struggle installing pygraphviz on Mac OSX Lion ([sudo] easy_install pygraphviz) I've tried to use it, but it crashes when I import it. Here you can see the error.
Any idea to solve it? Do I should install another aux library...?
