warnings

问题 So I'm working on a project in Python and trying to keep it up to standards with pylint and just generally . So, I have a source file, (We'll just call it a.py) #a.py import loggingsetup def foo(): log.info("This is a log message") But, I want to control what the logging looks like, so in loggingsetup I have something like: #loggingsetup.py import logging logging.root.setLevel(logging.DEBUG) consoleOut = logging.StreamHandler() consoleOut.setLevel(logging.INFO) consoleOut.setFormatter(logging

问题 Too long; didn't read The warnings.catch_warnings() context manager is not thread safe. How do I use it in a parallel processing environment? Background The code below solves a maximization problem using parallel processing with Python's multiprocessing module. It takes a list of (immutable) widgets, partitions them up (see Efficient multiprocessing of massive, brute force maximization in Python 3), finds the maxima ("finalists") of all the partitions, and then finds the maximum ("champion")

问题 I have a php application that I have just re-factored. Unfortunately it spewing out warnings like: Warning: preg_match() expects parameter 2 to be string, object given in /home/yacoby/dev/netbeans/php/Zend/Db/Select.php on line 776 Which is impossible (or very hard work) to work out the issue as I don't have a callstack so can't tell which parts of my code are causing the warning and there is a lot of code. I need a method to either treat warnings like errors (In that the application dies and

问题 I have a code which, at some point shows a warning, I think that it is having a problem calculating a mean() I would like to know if there is any way to force python to tell me where, or which line, or whatever more information than just this message: C:\Python27\lib\site-packages\numpy\core\_methods.py:55: RuntimeWarning: Mean of empty slice. warnings.warn("Mean of empty slice.", RuntimeWarning) C:\Python27\lib\site-packages\numpy\core\_methods.py:79: RuntimeWarning: Degrees of freedom <= 0
