python - python2.7有内存分析器吗？

Question

我需要检查我在 python 中使用的对象的内存统计信息。
我遇到了 guppy 和 pysizer，但它们不适用于 python2.7。
是否有适用于 python 2.7 的内存分析器？
如果没有，我可以自己做吗？

您可能想尝试根据您的具体情况调整以下代码并支持您的数据类型:

import sys


def sizeof(variable):
    def _sizeof(obj, memo):
        address = id(obj)
        if address in memo:
            return 0
        memo.add(address)
        total = sys.getsizeof(obj)
        if obj is None:
            pass
        elif isinstance(obj, (int, float, complex)):
            pass
        elif isinstance(obj, (list, tuple, range)):
            if isinstance(obj, (list, tuple)):
                total += sum(_sizeof(item, memo) for item in obj)
        elif isinstance(obj, str):
            pass
        elif isinstance(obj, (bytes, bytearray, memoryview)):
            if isinstance(obj, memoryview):
                total += _sizeof(obj.obj, memo)
        elif isinstance(obj, (set, frozenset)):
            total += sum(_sizeof(item, memo) for item in obj)
        elif isinstance(obj, dict):
            total += sum(_sizeof(key, memo) + _sizeof(value, memo)
                         for key, value in obj.items())
        elif hasattr(obj, '__slots__'):
            for name in obj.__slots__:
                total += _sizeof(getattr(obj, name, obj), memo)
        elif hasattr(obj, '__dict__'):
            total += _sizeof(obj.__dict__, memo)
        else:
            raise TypeError('could not get size of {!r}'.format(obj))
        return total
    return _sizeof(variable, set())
