I installed memory_profiler on my system and ran this program
!/usr/bin/env python
from memory_profiler import profile
@profile(precision=4)
def my_func():
a = [1] * (10 ** 6)
b = [2] * (2 * 10 ** 7)
del b
return a
if __name__ == '__main__':
my_func()
after running python fp.py it displayed
Filename: fp.py
Line # Mem usage Increment Line Contents
================================================
4 12.6992 MiB 0.0000 MiB @profile(precision=4)
5 def my_func():
6 20.3516 MiB 7.6523 MiB a = [1] * (10 ** 6)
7 172.8945 MiB 152.5430 MiB b = [2] * (2 * 10 ** 7)
8 20.5273 MiB -152.3672 MiB del b
9 20.5273 MiB 0.0000 MiB return a
but while running mprof run fp.py it returns
No command 'mprof' found, did you mean:
Command 'sprof' from package 'libc-dev-bin' (main)
Command 'mlprof' from package 'mlton-tools' (universe)
Command 'pprof' from package 'tau' (universe)
Command 'prof' from package 'profphd' (universe)
Command 'gprof' from package 'binutils' (main)
Command 'gprof' from package 'binutils-multiarch' (main)
mprof: command not found
how should i plot the memory usage graph is there any other library.
I believe it has something to do with PATH.
Depends on the linux distribution, executables from pip can be installed at different locations.
For ubuntu, it is very likely in the following locations:
pip3 install memory-profiler --user
) You can either add it into PATH (see this ) or run the script with full path (ie /usr/local/bin/mprof run fp.py
)
You've to run mprof run filename.py
, mprof plot
commands on terminal.
