ip链接显示:

我运行mprof run some-executable并生成了一个*.dat文件。

文件的每一列代表什么*.dat意思？

vikas@some-host$ cat mprofile_20150224012014.dat              
CMDLINE python ../asl
MEM 0.332031 1424769614.8950
MEM 7.593750 1424769614.9954
MEM 8.816406 1424769615.0957
MEM 8.816406 1424769615.1960

第一/第二/第三列代表什么？

[编辑]： 我也无法运行 mprof run --python。这是我收到的错误（导入错误）......看起来它无法获取配置的定义

(virtualenv)vikas@host:$ ./mprof run --python ../myfile.py

mprof：每0.1s采样一次内存

作为 Python 程序运行...

我能够生成* .dat文件：

vikas@server:~/memory_profiler-0.36$ ./mprof run --python test_sl.py 
vikas@server:~/memory_profiler-0.36$ ls *.dat
mprofile_20151001035123.dat

但是，当我尝试绘制图形时，它说“ matplotlib需要绘制”

vikas@server:~/memory_profiler-0.36$ ./mprof plot --output=plot.png 
matplotlib is needed for plotting.

我有想念吗？

我正在分析的函数是其中的run（）：file_to_be_profiled.py

#!/usr/bin/python

import os, sys, commands
from memory_profiler import profile
from guppy import hpy

@profile

    d = {}
    l = []
    hp = hpy()
    before = hp.heap()

    d["k1"] = 'val1'
    d["k2"] = 10
    count = 0
    while (count < 9):
        l.append(count)
        print 'The count is:', count
        count = count + 1

如何让gcc编译器报告从整数到无符号整数的转换？是否有一个选项/ arg我可以传递给gcc编译器来标记这样的转换？

我的集群节点主要绑定到 eth0 和 bond0 接口：
