logger configuration overrides project's logger

[helmanofer]

in my main code I configure:

logging.basicConfig(format='%(asctime)s : %(levelname)s : %(message)s', level=logging.INFO)

But I get lda's logger configuration:

INFO:lda:<450> log likelihood: -111, per-word: -3.4701
INFO:lda:<460> log likelihood: -111, per-word: -3.4701
INFO:lda:<470> log likelihood: -111, per-word: -3.4701
INFO:lda:<480> log likelihood: -111, per-word: -3.4701

If in lda's init file I mark out line 11:

...
__version__ = pbr.version.VersionInfo('lda').version_string()

# logging.basicConfig(level=logging.INFO)
logger = logging.getLogger('lda')
logger.addHandler(logging.NullHandler())

I get the correct logger config:

2015-02-23 16:05:37,286 : INFO : <470> log likelihood: -111, per-word: -3.4701
2015-02-23 16:05:37,288 : INFO : <480> log likelihood: -111, per-word: -3.4701
2015-02-23 16:05:37,290 : INFO : <490> log likelihood: -111, per-word: -3.4701
2015-02-23 16:05:37,291 : INFO : <500> log likelihood: -111, per-word: -3.4701

I took this from gensim's init file.

Thanks. I've seen this problem in a few projects and would like to figure out what's the right way to setup logging properly. I'll look at the logging docs today.

Removing that line disables all logging, which isn't what we want.

Maybe the appropriate place to put basicConfig is in the __init__ for LDA.
