verbosity

Many scikit-learn functions have a verbose argument that, according to their documentation, "[c]ontrols the verbosity: the higher, the more messages" (e.g., GridSearchCV ). Unfortunately, no guidance is provided on which integers are allowed (e.g., can a user set verbosity to 100?) and what level of verbosity corresponds to which integers. I cannot find this information anywhere in the documentation. My question is, which integers map to which levels of verbosity? Higher integers map to higher verbosity as the docstring says. You can set verbosity=100 but I'm pretty sure it will be the same as

what is good practice for generating verbose output? currently, i have a function bool verbose; int setVerbose(bool v) { errormsg = ""; verbose = v; if (verbose == v) return 0; else return -1; } and whenever i want to generate output, i do something like if (debug) std::cout << "deleting interp" << std::endl; however, i don't think that's very elegant. so i wonder what would be a good way to implement this verbosity switch? The simplest way is to create small class as follows(here is Unicode version, but you can easily change it to single-byte version): #include <sstream> #include <boost

I recently started studying functional programming using Haskell and came upon this article on the official Haskell wiki: How to read Haskell . The article claims that short variable names such as x , xs , and f are fitting for Haskell code, because of conciseness and abstraction. In essence, it claims that functional programming is such a distinct paradigm that the naming conventions from other paradigms don't apply. What are your thoughts on this? Ionuț G. Stan In a functional programming paradigm, people usually construct abstractions not only top-down , but also bottom-up . That means you

The Python unittest framework has a concept of verbosity that I can't seem to find defined anywhere. For instance, I'm running test cases like this ( like in the documentation ): suite = unittest.TestLoader().loadTestsFromTestCase(MyAwesomeTest) unittest.TextTestRunner(verbosity=2).run(suite) The only number I've ever seen passed as verbosity is 2. What is this magic number, what does it mean, what what else can I pass? luc You only have 3 different levels: 0 (quiet) : you just get the total numbers of tests executed and the global result 1 (default) : you get the same plus a dot for every

Maven spews out far too many lines of output to my taste (I like the Unix way: no news is good news). I want to get rid of all [INFO] lines, but I couldn't find any mention of an argument or config settings that controls the verbosity of Maven. Is there no LOG4J-like way to set the log level? Jorge Ferreira You can try the -q switch. -q,--quiet Quiet output - only show errors -q as said above is what you need. An alternative could be -B , --batch-mode Run in non-interactive (batch) mode Batch mode is essential if you need to run Maven in a non-interactive, continuous integration environment.
