python内存分析

  • 安装
    首先安装memory_profiler和psutil
    pip install memory_profiler
    pip install psutil

  • 在需要分析的函数前面添加装饰器@profile
@profile()
def call():
    a = list()
    for i in range(10000 * 100):
        a .append(i)

运行call后的输出:
Line # Mem usage Increment Line Contents
================================================
283 40.1 MiB 40.1 MiB @profile
284 def call():
285 40.1 MiB 0.0 MiB a = list()
286 44.1 MiB 0.0 MiB for i in range(10000 * 10):
287 44.1 MiB 0.3 MiB a .append(i)
