I'm getting an error whenever I try to start swift related to python. How do I fix this?
bash-3.2$ swift --version

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

CUDA 11.5
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
The script works just fine on my Jetson Nano
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.
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...?

I installed the iphone-python package from Cydia, but the HelloPython app closes immediately when I run it from Springboard.
This may be a red herring, but I found the .py file in Terminal and tried to run it with python and got a python error:

I'm running 4.3.3.
How can I get this app working, so I'll have a working example of PyObjC?
Well due to the changes in the way executables on the new ios run, the dynamic library has become corrupt. The mach-o will no longer run due to the upgraded objective-c so a workaround would be to compile pyobjc from source and run normaly. The only ptoblem with that is that the iphone's version of pyobjc is built for uikit so you would need to find saurik's (Jay Freeman) source code and compile it. I might do that for myself so ill post back with a deb file if i do.
