Description
Reproducing code example:
Write a demo.py:
from __future__ import print_function
import time
import numpy as np
import six
if six.PY3:
timer_func = time.process_time
else:
timer_func = time.clock
n = 1000
start = timer_func()
precise = 2
for i in range(n):
np.round(np.array(range(i)), precise)
end = timer_func()
print(end-start)Then run it like this:
# Py2
python -m cProfile -o demo-py2.prof demo.py
# Py3
python -m cProfile -o demo-py3.prof demo.pyAnd view the profiles with snakeviz pip install snakeviz:
# Under Python2's virtual env:
snakeviz demo-py2.prof
# Under Python3's virtual env:
snakeviz demo-py2.profGet web page:
And the purple part it time cost on loading packages.
