python的memory estimationpython有自带的sys模块能够让我们大概估算object所占用的内存,但这个功能有一定的缺陷: import sys obj1 = [['abc'],['def'],['adc'],['dasd'],['asde']] obj2 = [['a'],['d'],['d'],['d'],['e']] size1 = len(obj1) size_obj1 = sys.getsizeof(obj1)...

我们前一篇,已经讨论了内存块,这是CPython内存管理模型里面一个基本的逻辑单位,当然block有明确的基本单位那就是8个字节,而对于不同Python对象来说,有着不同类型尺寸(size class)来描述小型Python对象的内存分配需求,内size class index维系内存池和当前块用于什么size class的小型Python对象内存分配的关系。
memory_profiler是一个用于监控 Python 程序内存使用情况的库。通过装饰器@profile,可以记录函数执行过程中内存的占用情况,帮助开发者找出内存泄漏的位置。 pip install memory-profiler from memory_profiler import profile @profile def my_function():# 模拟内存泄漏large_list=[ifori in range(1000000)]returnlarge...
print("get_size(d1):", get_size(d1)) 非常好,但是如果我们不需要这个功能呢?我们能强制解释器来指定类的列表对象使用__slots__命令: classDataItem(object): __slots__= ['name','age','address'] def__init__(self, name, age, address): ...
