i built program config file parser , cli options. my goal have order of priority : cli options configuration mandatory configuration file hardcoded default configuration while parsing cli arguments argp need read path config file first (which not option) other cli options override config file settings. as described in glibc argp documentation, options read first non-option arguments, unless use argp_in_order flag. in case arguments read first last (option or not). in case, first mandatory argument path config file. behave expected, except usage output. i have : usage: myprogramm [option...] configurationfile i need : usage: myprogramm configurationfile [option...] is there way place non-optional arguments first in usage output?

when use sklearn built decisiontree,examples: clf = tree.decisiontreeclassifier() clf = clf.fit(x,y) result = clf.predict(testdata) x training input samples,if there "none" in x,how it? decision trees , ensemble methods random forests (based on such trees) accept numerical data since performs splits on each node of tree in order minimize given impurity function (entropy, gini index ...) if have categorical features or nan in data, learning step throw error. to circumvent : transform categorical data numerical data : use example one hot encoder . here link sklearn 's documentation. warning : if have feature lot of categories (e.g. id feature) onehotencoding may lead memory issues. try avoid encoding such features. impute values missing ones. many strategies exist (mean, median, frequent ...). here link sklearn 's documentation. once you've done preprocessing , can fit decision tree data.

using sbt-native-packager plugin, what's best approach have app-writable directory? in configuration use enableplugins(javaserverapppackaging, systemdplugin, debianplugin, universalplugin) , works except app needs write files own functioning, under /usr/share/package-name/ sounds wrong wonder , how best that, if should use debain postinst scripts of try alter directory permissions mappings of universal pluin. adding new writeable directory in linux distribution means adding mapping linuxpackagemappings (documentation) . linuxpackagemappings += packagetemplatemapping( s"/opt/${(packagename in linux).value}" )().withuser((daemonuser in linux).value) .withgroup((daemongroup in linux).value) .withperms("755") you can see old sbt syntax in use javaserverapp plugin . note: should not set /usr/share/<packagename> directory writeable. contains executables , config files , should modifiable root user. cheers, muki
