Python script knows how much memory it's using
提问by ???u
How can a python script know the amount of system memory it's currently using? (assuming a unix-based OS)
python 脚本如何知道它当前使用的系统内存量？（假设是基于 Unix 的操作系统）
回答by Martin v. L?wis
If you want to know the total memory that the interpreter uses, on Linux, read /proc/self/statm.
如果您想知道解释器使用的总内存，请在 Linux 上阅读/proc/self/statm.
If you want to find out how much memory your objects use, use Pympler.
如果您想了解您的对象使用了多少内存，请使用Pympler。

I've used once snippet I found on ActiveStateand it seemed to work well. Actually it's using same method Martin v. L?wis suggested.
我曾经使用过在ActiveState 上找到的代码片段 ，它似乎运行良好。实际上，它使用的是 Martin v. L?wis 建议的相同方法。

I don't think there's a simple way to do this. As a practical matter, on a Unix OS I'd probably do something with os.getpid() and calling ps or reading entries in /proc.
我不认为有一种简单的方法可以做到这一点。实际上，在 Unix 操作系统上，我可能会使用 os.getpid() 并调用 ps 或读取 /proc 中的条目。
Python 2.6 adds sys.getsizeof(), which you could use in concert with gc.get_objects() to walk the size of the working set of objects:
Python 2.6 添加了 sys.getsizeof()，您可以将其与 gc.get_objects() 结合使用以遍历工作对象集的大小：
>>> print sum([sys.getsizeof(o) for o in gc.get_objects()])

I don't think that'd be a good idea in practice.
我认为这在实践中不是一个好主意。

I haven't used it, but you might take a look at heapy(http://guppy-pe.sourceforge.net/#Heapy), which looks to be a memory profiler for python programs.
我没有用过它，但你可以看看heapy( http://guppy-pe.sourceforge.net/#Heapy)，它看起来是 Python 程序的内存分析器。
