【问题描述】：

当我运行带有@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
    exec cmd in globals, locals
  File "<string>", line 1, in <module>
  File "monthly_spi_gamma.py", line 1, in <module>
    import indices
  File "indices.py", line 14, in <module>
    @profile
NameError: name 'profile' is not defined

谁能评论什么可以解决这个问题？我在 Windows 7 上使用 Python 2.7 (Anaconda)。

【问题讨论】：

如果问题已解决，请考虑接受您的回答。

【参考方案1】：

我通过使用 -l 选项解决了这个问题，即

$ kernprof.py -l my_code.py

【参考方案2】：

kernprof -l -b web_app.py

如果我们看到，这对我有用

kernprof --help

我们看到了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]
