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...?

I'm getting an error whenever I try to start swift related to python. How do I fix this?

I get the same error, because the swift REPL uses the python interpreter which homebrew installed at /usr/local/bin/python.
To avoid this you can
export PATH=/usr/bin:$PATH
swift
or
PATH=/usr/bin:$PATH swift
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:
Michaels-Mac-mini:~ mellis$ which python
/Users/mellis/Library/Enthought/Canopy_64bit/User/bin/python
Michaels-Mac-mini:~ mellis$ which ipython
/Users/mellis/bin/ipython
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:
from scipy import signal

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!

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.
