python - Windows 上的 Guppy/Heapy 和 Python 2.7.6

Question

我刚刚安装了 guppy 0.1.10。然后输入 Ipython 2.1.0

from guppy import hpy
hp = hpy()

使控制台崩溃，即 Windows 告诉我，python.exe 刚刚崩溃。有什么解决方法吗？还是重的替代品？

Answer 1

我对 guppy/heapy 也有同样的问题。 Guppy 目前有点过时了。有某种补丁，但我找不到了。但是它在 python 2.7 中对我不起作用。由于操作系统架构(64 位!？)，您可能还会遇到问题。

关于内存分析技术还有其他问题:

• Python memory leaks
• Which Python memory profiler is recommended?

我个人认为最有值(value)的替代方案是:

• https://pypi.python.org/pypi/memory_profiler
• https://launchpad.net/meliae
• http://mg.pov.lt/objgraph/

计算对象的大小并自行跟踪它也很有用。我详细阐述了我在 StackOverflow 问题之一 ( https://stackoverflow.com/users/216356/noctis-skytower ) 中发现的一些代码(最初由 Approximately how much memory would a list of 80000 items consume in python? 编写)与 Python 2.7 兼容(也应该在 3 中工作):

totalSizeOf = lambda obj: sum(map(sys.getsizeof, explore(obj, set())))
def explore(obj, memo):
    loc = id(obj)
    if loc not in memo:
        memo.add(loc)
        yield obj
        # Handle instances with slots.
        try:
            slots = obj.__slots__
        except AttributeError:
            pass
        else:
            for name in slots:
                try:
                    attr = getattr(obj, name)
                except AttributeError:
                    pass
                else:
                    #yield from explore(attr, memo)
                    for bar in explore(attr, memo):
                        yield bar
        # Handle instances with dict.
        try:
            attrs = obj.__dict__
        except AttributeError:
            pass
        else:
            #yield from explore(attrs, memo)
            for bar in explore(attrs, memo):
                yield bar
        # Handle dicts or iterables.
        for name in 'keys', 'values', '__iter__':
            try:
                attr = getattr(obj, name)
            except AttributeError:
                pass
            else:
                for item in attr():
                    #yield from explore(item, memo)
                    for bar in explore(item, memo):
                        yield bar
