Can I render an openCV animation from a background thread in Python?
Here is my attempt:
import cv2
import numpy as np
from time import sleep
bitmap = np.zeros((512,512,3),np.uint8)
import threading
import time
def update_bitmap():
for i in range(512):
bitmap[i,i,:] = 128
sleep(1/32)
threading.Thread(target=update_bitmap).start()
def refresh_gui():
hz = 30
delta_t = 1 / hz
t = time.time()
while True:
sleep(0.001)
if time.time() > t+delta_t:
t += delta_t
cv2.imshow("Color Image", bitmap)
cv2.waitKey(1)
threading.Thread(target=refresh_gui).start()
try:
while True:
print('tick')
sleep(1)
except KeyboardInterrupt:
cv2.destroyAllWindows()
exit(0)
However it fails with:
> python test.py
tick

I really want my renderer to be in a separate thread.
So much cleaner!
Can it be done?
This doesn't answer the question, but it solves the problem:
import cv2
import numpy as np
from time import sleep
import threading
import time
bitmap = np.zeros((512,512,3),np.uint8)
def update_bitmap():
for i in range(512):
bitmap[i,i,:] = 128
sleep(1/32)
def main():
threading.Thread(target=update_bitmap).start()
hz = 30
delta_t = 1 / hz
t = time.time()
try:
while True:
sleep(0.001)
if time.time() > t+delta_t:
t += delta_t
cv2.imshow("Color Image", bitmap)
cv2.waitKey(1)

I was trying to zip up an application bundle using shutil.make_archive using zip format, like this
app_pkg = '/path/to/my.app'
shutil.make_archive(app_pkg, 'zip', '/path/to/installer')
The produced zip file extracts to /path/to/installer without issues.
But the app inside the installer folder, i.e., /path/to/installer/my.app, crashes when double-clicked.
The full crash log looks like this

If I zip up the /path/to/installer folder using macOS's own zip utility, the app works fine.
I made a binary comparison between both results and couldn't find obvious differences, except for the .DS_Store file. But I never had issues with .DS_Store before in this sort of scenarios, so I don't believe that's the cause.
Where am I wrong?
Found the issue. shutil.make_archive() does not follow symlinks as of python 3.9.5. So the symlinks are not included in the zips.
This corrupts the lib and executable bundles such as *.framework's.
A workaround I round is to use gztar instead of zip, which preserves the essential symlinks.
shutil.make_archive(app_pkg, 'gztar', '/path/to/installer')
So I am trying to make a small GUI in python (version 3.8.3) using tkinter. I wrote the whole script in the PyCharm IDE and I was able to run it without issue and still can. However trying to run it from the command line results in a crash and I get the following output:

I can connect to Postgres via the command line no problem, however if I try to connect via Python using the psycopg2 module I get the error below. Interestingly I have just tried connecting with PSeqal.app and it crashes with the same error.
Environment:
MacOS: 10.13.3
Xcode 9.2
Python: 3.6.4
Connection module: psycopg2
Postgresql: 10.3
Script:
Here is my simple connection script which is trying to connect via Python to Postgresql:
def connect(self, params):
""" Connect to the PostgreSQL database server """
conn = None
try:
# connect to the PostgreSQL server
logging.info('Connecting to the PostgreSQL database...')
conn = psycopg2.connect(**params)
# create a cursor
self.cursor = conn.cursor()
except (Exception, psycopg2.DatabaseError) as error:
print(error)
finally:
if conn is not None:
conn.close()
logging.warning('Database connection closed.')
Error:
Script output:

What I have tried so far:
Upgraded Python to 3.6.4 from 3.5.1
Rebuilt all dependent libraries including psycopg2 to make sure they are High Sierra compatible (I hope)
Reinstalled Postgres from scratch
Upgraded Xcode + tools
So I'm at a bit of a loss as to what to try next? Has anyone else run into this? Any pointers to where to look? Anything that helps me get this working would be greatly appreciated thanks!
So it looked like the psycopg2 library was the culprit and this fixed it for me:
$pip3 uninstall psycopg2
...
Successfully uninstalled psycopg2-binary-2.7.4
$pip3 install psycopg2-binary --no-binary :all:
Collecting psycopg2-binary
Downloading psycopg2-binary-2.7.4.tar.gz (426kB)
100% |---| 430kB 649kB/s
Skipping bdist_wheel for psycopg2-binary, due to binaries being disabled for it.
Installing collected packages: psycopg2-binary
Running setup.py install for psycopg2-binary ... done
Successfully installed psycopg2-binary-2.7.4
$python3 test.py
Connecting to the PostgreSQL database...
All good.
Database connection closed.
The reason I believe is something to do with the fact I was trying to build psycopg2 on a 2010 era MBP specifically and it has a compatibility issue with the hardware - probably the 2.66 GHz Intel Core i7 processor this machine has.
Thank you #Laurenz Albe and #joop for quick replies, pointers and insights, you helped narrow me down to this answer which I hope will stay stable for the duration of this job ;) Cheers!
According to the stack trace, that error occurs in the PostgreSQL client, in this harmless piece of code:
/*
* initPQExpBuffer
*
* Initialize a PQExpBufferData struct (with previously undefined contents)
* to describe an empty string.
*/
void
initPQExpBuffer(PQExpBuffer str)
{
str->data = (char *) malloc(INITIAL_EXPBUFFER_SIZE);
if (str->data == NULL)
{
str->data = (char *) oom_buffer; /* see comment above */
str->maxlen = 0;
str->len = 0;
}
else
{
str->maxlen = INITIAL_EXPBUFFER_SIZE;
str->len = 0;
str->data[0] = '\0';
}
}
I found this and this question dealing with similar problems.
Illegal instruction should mean that execution encountered an instruction code that does not exist, which is either a compiler bug or means that the code was built for a processor with a different instruction set.
The problem is likely somewhere in the procedure with which PostgreSQL was built. You should bring this complaint to the packagers who built the binaries you are using.
I'd like to check out matlab engine for Python. I installed it according to the directions here. But just the line
import matlab.engine
causes my program to quit with exit code 139, which I understand is some kind of memory fault. I'm running Python 2.7.10 (the Anaconda 2.3.0 distribution), Matlab 2014b, MacOS 10.10, x86_64.
Edit: Here is the stack trace.

Edit 2: I'm not sure which kind of trace is more helpful, but I also tried generating a trace with the trace_calls function defined here. These were the last few lines of that:

Does anyone have any idea how I can fix this?
Thanks very much for any help you can provide.
