Hi list. I've tried Googling for this and I checked the Python docs, but to no avail.
What is the best way to debug memory usage in a Python script? I'd like to see what objects are using the most memory. Ideally this would be aware of references too. So if I have a small list that contains (references rather) some large variables, then I could see that the global list variable was responsible for X MB that couldn't be collected by the garbage collector. It would be nice if it could be used in a similar way to the 'du' Linux command. eg: eg output: >>> mem_debugger.pretty_print() A (type: list): 8 bytes, 10MB - a (type: string): 6 MB, 0 bytes - b (type: string): 4 MB, 0 bytes B (type: dict): 8 bytes, 5 MB - d (type: string): 3 MB, 0 bytes - c (type: string): 2 MB, 0 bytes In the output above, the 1st size is the memory used by the object itself, and the 2nd size is the memory used by objects it refers to. A & B are global vars (a string and a dict), a,b,c, and d are strings that were added to A & B at some point in the past, and aren't refered to by anything else. Also, the output is in descending order of size. Are there any tools/modules/etc I can use like this? David. -- http://mail.python.org/mailman/listinfo/python-list
