python line_profiler(kernprof)没有使用最小的例子

这是我的npm install -g generator-meanjs@0.1.12

script.py

我安装了@profile def primes(n): if n == 2: return [2] elif n < 2: return [] s = range(3, n + 1, 2) mroot = n ** 0.5 half = (n + 1) / 2 - 1 i = 0 m = 3 while m <= mroot: if s[i]: j = (m ** 2 - 3) / 2 s[j] = 0 while j < half: s[j] = 0 j += m i += 1 m = 2*i + 3 return [2] + [x for x in s if x] number = 40000 elts = primes(number)

line_profiler

并按如下方式运行

$ pip install line_profiler

这很奇怪......没有计时结果!

所以我调查了转储,但也没有运气:

$ kernprof -l -v script.py
Wrote profile results to profiling.py.lprof
Timer unit: 1e-06 s

我是如何使用此库错误的?
