I was trying to resize an image in a function using opencv that is called within a continous loop for socket transmissions and I obtained this error

The code that I used that I assume generates this error is
import numpy as np
import cv2
class video_read():
def __init__(self, filename):
self.cap = cv2.VideoCapture(filename)
def read_frames(self):
frame = self.cap.read()[1]
image = cv2.imencode('.png', frame)[1]
image_resized = cv2.resize(image, (width/10, height/10))
return image_resized
Could someone point out to me what did I do wrong that called this exception?

I got this (not particularly helpful, in my eyes) crash message and was wondered what the usual suspect was for this/where I'm best to look? I'm getting this when I navigate using a NavigationLink to another View. I know from some research that this crash tends to have a different cause each time, but I wondered if the stack trace would give any clues?
Each crash companies about the same invalid attribute id: 83753. Any way I can track something down using this ID?

Hey StackOverflow detectives.
I've been pulling my hair out for a few months trying to figure out the crashes which happen at a line never exists.
In the crash log below, CustomClass.swift does exist but the line 25 doesn't.
What would be the true reason for this crash?
Hint: we run heavy processing and allocate a lot of memory (about 700MB) in the background that was written in c++, which is in OUR_CUSTOM_FRAMEWORK below.

I installed gnuradio via macports. I have been able to install the majority of the other blocks via macports, however I was wanting to start playing with DECT and the block was not listed on macports. So I manually went to install it via the following git location:https://github.com/pavelyazev/gr-dect2
When I installed with the standard install, gnuradio did not see the block at all. After researching I found others having success by modifying the cmake call like that below.
cd gr-dect2/
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/opt/local ..
make
sudo make install
I was then able to see the dect2 block in gnuradio, however when I went to run the example dect2.grc project I was getting the below message:
Traceback (most recent call last):
File "/Users/krotovd/gr-dect2/grc/top_block.py", line 32, in <module>
import dect2
ImportError: No module named dect2
So I found where the other modules were installed, deleted the build directory and called the original build/install commands with a modification on cmake as shown below.
cmake -DCMAKE_INSTALL_PREFIX=/opt/local/Library/Frameworks/Python.framework/Versions/2.7
Now when I open gnuradio-companion and proceed to open the detc2.grc project it crashes with the error in the title:
Loading: "/Users/krotovd/gr-dect2/grc/dect2.grc"
Fatal Python error: PyThreadState_Get: no current thread
Abort trap: 6
Has anyone been able to successfully install a dect2 block for gnuradio in Mac? Seems like this has been an issue for some time now. Anyone have any ideas on how I might be able to resolve this issue?
Below is a excerpt of my error report. I am inserting the except due to the size, but I beleive what is important should be listed.

try my cmake alias, it always worked for me
alias cm='cmake -DPYTHON_EXECUTABLE=/opt/local/bin/python2.7 -DPYTHON_INCLUDE_DIR=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Headers -DPYTHON_LIBRARY=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Python -DGR_PYTHON_DIR=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages -DCMAKE_INSTALL_NAME_DIR=/opt/local/lib -DCMAKE_SYSTEM_PREFIX_PATH="/opt/local;/usr" -DCMAKE_INSTALL_PREFIX=/opt/local'
I've developed a GitHub repo with an example of a multiprocess script in python2.7 for plotting. Basically, the script allocates one process to generate the data, and such data are passed via a queue to a second process that is responsible to generate the plot. When I run both the examples 'multiproc_processIPC.py' or 'multiproc_poolQUEUE.py' I get the following error.
Note that this error came up AFTER upgrading my mac to OSX Sierra.
Has anyone a clue of the origin of this issue?
Any help will be highly appreciated

Try setting the "start method" to "spawn" instead of the default of "fork". See https://docs.python.org/3/library/multiprocessing.html#contexts-and-start-methods for further details.
This worked for me on a similar problem.
Ok, more info: If I run a first process from terminal, whose script 'visl.py' is:
#!/usr/bin/env python
from multiprocessing import Process
import sys
sys.path.insert(0, './lib')
import visualizer
visualizer.Visualizer()
and then a second process from a different terminal instance, whose script 'logr.py' is:
#!/usr/bin/env python
from multiprocessing import Process
import sys
sys.path.insert(0, './lib')
import logger
args_logger = {'sampling_time_ms': 5, 'plotting_time_ms': 100}
logger.Logger(args_logger)
It works. Then: how to run two python processes from a single script?
I'm using wxWidgets, and I have a wxTreeCtrl set up with a root and a single child. I'm setting client data on the child and it works fine until the window closes, at which point I get a bus error, which I'm assuming is coming from wxWidgets attempting to delete my client data.
Here's my client data struct:
struct MapPtrCtr {
Map* map;
MapPtrCtr(Map* map) : map(map) {}
};
Here's how I set the client data (note that here, map is std::shared_ptr<Map>):
wxTreeItemId childNode = mapTree->AppendItem(node, map->getTitle());
mapTree->SetItemData(childNode, (wxTreeItemData*) new MapPtrCtr(map.get()));
Here's the error I get:

Any suggestions? I'm not sure how to properly use wxTreeItemData because there's very little documentation on it. The docs say to make sure to initialize the struct with new, and I do, so I'm not sure why there's a problem.
That was quick. I figured out how to properly use wxTreeItemData: you have to subclass it, not just cast to it. The following client data class works:
class MapPtrCtr : public wxTreeItemData {
public:
Map* map;
MapPtrCtr(Map* map) : map(map) {}
};
