I’m trying to create a thread, that does stuff in the background. I need to be able to effectively ‘pause’ it when I need to and ‘resume’ it again later. Also, if the thread is in the middle of doing something when I ‘pause’ it, it should make the calling thread wait until it finishes what it’s doing.
I’ve created a little GUI for one of my scripts. All is working well.
I’m trying to figure out multi-threading programming in python. Here’s the simple task with which I want to compare serial and parallel speeds.
I ran simple python script on Raspberry Pi 3. This script is responsible to open video device and stream data (800×600) to HTTP endpoint using MJPEG. When I receive this stream one of my Raspberry Pi cores works on 100%. It possible to run OpenCV with multi threading?
I’m launching a program with subprocess on Python.
The sequence I would like to accomplish:
The python
threading
documentation states that “…threading is still an appropriate model
if you want to run multiple I/O-bound tasks simultaneously”,
apparently because I/O-bound processes can avoid the GIL that prevents
threads from concurrent execution in CPU-bound tasks.
I’m running this simple code:
I was really confused by sys.exit() in python.
In python documentation, it says “Exit from Python”; does that mean when sys.exit() is called in a python program, the process will exit? If so, the code below shows a different result:
What’s the difference between the threading and thread modules in Python?
