I'm getting a strange error "Process finished with exit code -1073741819 (0xC0000005)" running python 3.7 on a windows machine. The process just crashes. The error comes in random time. It seems to appear inside a thread.
Is there someway to get more information where exactly the error comes from? Right now my only solution is to add logging, but that is really time consuming.
Thanks a lot for any hint.
I've seen this error occur when a Python script has infinite (or very deep) recursion and the following code is used to increase the recursion limit:
import sys
sys.setrecursionlimit(4000)
I would guess that the error means we are running out of memory.
I had the same issue, not long time ago and I have solved this with the following solution:
reinstall python – you don't have python33.dll in c:\WINDOWS\system32\
Maybe you have different python versions – look at folders in root of c:
If yes, then point to your version of python.exe in pyCharm > Settings > Project Interpreter

Heyo all. I just got a raspberry pi 4 and I moved my code from my PC to the pi and when I ran and fixed it so it could run. I started to notice that it printed out more then it should. I looked it up but I couldn't find any help or reason why it does it. Code is
#!/usr/bin/python3
from os import system
system('cls')
print('heyo')
output is
I have found out if I add a sleep timer I no longer get that problem.
I found out what caused it that is why I did not have code from my main program but I never found out exactly why it does it nor how to fix it without sleeping.
Notes: originally wrote it on windows 10 on my main PC I ported it over to my PI on the raspberry PI OS lite (I assume it is a Linux base OS). I changed the "clear" command to "cls" cause I am used to it. I am using VS code via SSH to the file. I am also using SSH to start the program. I run the code as:
./main.py
I did chmod +x test.py I am using python version 3.6.7. I am sorry if this seems basic or I made it way to confusing or there is a super super simple way to fix it (besides time.sleep). Thank you all for any help/input. Have a good night or good day.
Edit: I did not change anything but now it works for some reason. I have no clue why or how but for some reason it does.
Good Day All,
I finished writing the site blocker process and then i renamed the "py" file by appending "w", double clicked to run it yet the process did not show up in the task manager. I tried it a few times and yet nothing showed up. Mind you I am on Win 10 OS.
You have any suggestions to help fix this such that is shows up in the task manager as pythonw.exe process ?
If the process isn't showing up in the Task Manager, it's very likely that it's immediately quitting with an error. Even trivial changes to the code cause this to occur. Without the console showing output it's hard to tell what that error is. Try renaming the file back to filename.py and running it to see if an error is occurring.
Another possibility is that the script is completing so fast you don't have time to see it. Did it run instantaneously when it was named filename.py?
I've had a strange occurance. I stopped a python script manually, but its still running. It shows it as stopped in my IDE (Spyder) but I can see it's still running in task manager. I also know it still processing because its still outputting files to a directory.
Does anyone know why this is happening and how I can prevent it on a go forward?
Got it, i needed to add Exception to my except statement. Thanks gerosalesc and Dot_Py for your help.

Here is a Python 3.4 user, in VS 2013 and PTVS...
I'd written a program to plot something by Matplotlib... The output had been generating and everything was ok...
So, I closed VS and now I've opened it again after an hour, running the very script, but this time as soon as I press F5, a window appears and says Python has stopped working...
There is a short log in the output window, which asserts that:
The program '[9952] python.exe' has exited with code -1073741819 (0xc0000005) 'Access violation'.
Who could decrypt this error, please?!...
Kind Regards
.........................................
Edit:
I just tested again with no change... The error has been changed to:
The program '[11284] python.exe' has exited with code -1073741819 (0xc0000005) 'Access violation'.
Debug shows that when the program points to the drawing command of the matloptlib, i.e. plt.show(), this crash will happen...
All of the attempts sounds futile...
Even removing the VS is a challenging stuff... and as people consider, changing the OS is the most stable way to get rid of VS in the presence of such anomalies regarding its libraries...
So... I changed the OS... and installed the VS and PTVS again...
It seems to be a problem with your python and PTVS. Try to remove every .pyc file and have another go at it
Beginner here. I am trying to figure out how to modify a running process on a linux system using Python.
Example: I have a python program that takes in as an argument a PID. My goal is to use this PID and get info about the running process with that PID.
(1) Find where it is located in memory
(2) Where is the instruction pointer
(3) Modify the program such that the next executed instruction is something else
(4) Return the pointer back to the next legitimate instruction
(5) Let the original process execute as it should have
I am trying to develop a POC to show how a small piece of code can be injected into a running process to just print 'hello' to stdout and not disturb the rest of the process.
I looked up trace and some other modules but they all seem to do with following the currently executing python process. Also looked at pyhook, but its mainly to trap signals from keyboards etc.. additionally, I looked up pygdb a bit.
Can anyone please point me to some modules that might be useful, or some code samples. I tried googling for "python inspect process PID" etc.. did not get anything very useful.
Any help is very appreciated.
Thanks!
Also a newer python user. Can you do all these things with just the command line? If so then you could use os.system('[command]') or the subprocess module. For example you could use the pmap command to get the memory mappings. As for 2-5 I have no experience there. Good Luck.
