当我运行使用@profile注释的代码时出现以下错误:
Wrote profile results to monthly_spi_gamma.py.prof
Traceback (most recent call last):
File "/home/james.adams/anaconda2/lib/python2.7/site-packages/kernprof.py", line 233, in <module>
sys.exit(main(sys.argv))
File "/home/james.adams/anaconda2/lib/python2.7/site-packages/kernprof.py", line 223, in main
prof.runctx('execfile_(%r, globals())' % (script_file,), ns, ns)
File "/home/james.adams/anaconda2/lib/python2.7/cProfile.py", line 140, in runctx

@profile
NameError: name 'profile' is not defined
有人可以评论什么可以解决问题吗?我在Windows 7上使用Python 2.7(Anaconda)。
答案 0 :(得分:3)
我使用-l选项解决了这个问题,即
$ kernprof.py -l my_code.py
答案 1 :(得分:0)
kernprof -l -b web_app.py
这对我有用,如果我们看到
kernprof --help
我们看到一个包含在内置命名空间中的选项
usage: kernprof [-h] [-V] [-l] [-b] [-o OUTFILE] [-s SETUP] [-v] [-u UNIT]
[-z]
script ...
Run and profile a python script.
positional arguments:

-h, --help show this help message and exit
-V, --version show program's version number and exit

-b, --builtin Put 'profile' in the builtins. Use
'profile.enable()'/'.disable()', '@profile' to
decorate functions, or 'with profile:' to profile a

-o OUTFILE, --outfile OUTFILE
Save stats to <outfile> (default: 'scriptname.lprof'
with --line-by-line, 'scriptname.prof' without)
-s SETUP, --setup SETUP

-v, --view View the results of the profile in addition to saving
