Muting the LLVM IR debug output when using Numba?

问题:

I am wanting to use Numba in one of our in-house client libraries, however there's a debug dump of the LLVM IR code every time my code JITs something. Is there a setting in Numba or in LLVM that I can change so as to mute this stuff: http://i.imgur.com/Vkankxe.png ?

Thank you.

回答1:

If you want to stay with the release version of numba 0.11, and you can't control the python optimization level, this will work (just tried it myself):

import logging

def disableNumbaLogging():
    import numba.codegen.debug

    llvmlogger = logging.getLogger('numba.codegen.debug')
    llvmlogger.setLevel(logging.INFO)

回答2:

Try invoking python -O. This way, basic optimizations will be enabled and IR dump will be silenced.

this issue was corrected in the numba code on github. someone left a debug flag set to True.
