Hi It might take me a little time to explain this but here goes. Firstly I'm not using the latest upto date python releases so my first plan is to try more upto date rels of python and win32 libs, as this has fixed problems for me in the past (Don't like doing this as it usally breaks stuff and sys admin are slow to update software, although they do a cracking job, just covering my back.) I've created a build script for my companies...

Python/wxPython Reducing memory usage.

by: lotmr | last post by:

I have previously posted a simple app I am working on, and while I love python and wxWindows, after checking the memory usage on such a simple app (system try application launcher) I see that it climbs to over 17mb! I have reduced all my imports to the bare workable minimum and that just gets it under 17mb. Is there any way that I could compile or optimize the my program and/or its memory usage? (Note: I don't have a problem with making...

Memory problem

by: Rolf Wester | last post by:

Hi, I have a strange (for me) memory problem. When running a loop in a Python program memory usage increases from about 4% up to 100%. I do a gc.collect() every loop cycle but this doesn't help. There are about 67000 objects that are tracked by the garbage collector. This number does vary a little bit but does not increase on average whereas the memory usage does. The number of garbage objects (len(gc.garbage()) is zero. This is a very...

Re: "Help needed - I don't understand how Python manages memory"

by: Steve Holden | last post by:

Hank @ITGroup wrote: It doesn't really make that much sense to watch memory usage as you have been doing. Your first test case appears to trigger a specific pathology, where the memory allocator actually returns the memory to the operating system when the garbage collector manages to free all of it. Most often this doesn't happen - a chunk of memory might be 99.99% free but still have one small piece used, and so while there is a large...

Re: python has memory leak?

It does demonstrate that memory usage can remain at or near peak memory usage even after the objects for which that memory was allocated are no longer live in the process. This is only a leak if peak memory goes up again each time you create any new objects. Try repeated allocations of a large dictionary and observe how memory...

Problem With Comparison Operator <=> in G++

by: Oralloy | last post by:

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
