i have created userstoremanager implementation loads correctly via component class. however, need userstorecountretriever implementation allow user store work correctly. have extended jdbcuserstorecountretriever , added class name count implementation advanced property. have registered service in component. when user search following message: "error while listing users. error : exception occurred while trying invoke service method countusers". on console, following stack trace: ...caused by: java.lang.nullpointerexception @ org.wso2.carbon.identity.user.store.count.util.userstorecountutils.getcounterinstancefordomain(userstorecountutils.java:136) it looks can't find, or can't load class required implement count. class in same jar file user store.

i'm using sqlsrv extension php , have problem fetching rows simple query. query select should return 133228 rows when trying display rows 15. i've searched answer couldn't find solution , first time using extension. i've found answer previous question same problem in case problem double calling of sqlsrv_fetch_array, don't have sure. here query: $sql = 'select * viewproduct'; $params = array(); $options = array('scrollable' => sqlsrv_cursor_keyset); $stmt = sqlsrv_query($dbremote, $sql, $params, $options); $count = sqlsrv_num_rows($stmt); if ($count === false) echo "error in retrieveing row count."; else echo $count; //$rows = array(); while ($row = sqlsrv_fetch_array($stmt, sqlsrv_fetch_assoc)) { print_r($row); echo "<br>"; //$rows[] = $row; } as said above query returns 15 when should 133228 rows. what missing? thank in advance.

i know why not recommended have http body, see: http request body but have third-party service mongodb paas lets query sending http body (the filter clause in http body). doesn't support same query via http post. http body httpclient gives protocolviolationexception complains wrong verb. in humble opinion, httpclient should discourage non-standard usages (similar adding headers via tryaddwithoutvalidation ) not make them impossible. world not perfect after all. httpclient stands in way , paas provider not change apis suit http client. i read numerous related questions here in , many answers talking why bad have http body , should never it. however, have no control in case. how can work around problem system.net.http.httpclient ?

i'm using boost::python export c++ functions expect void* . interpret raw memory (an array of bytes) internally. think read , write special purpose device. how pass python bytearray such function? i have tried using ctypes.c_void_p.from_buffer(mybytearray) doesn't match signature of function. here's minimal example: #include <boost/python.hpp> void fun_voidp(void*) {} boost_python_module(tryit) { using namespace boost::python; def("fun_voidp", fun_voidp); } and @ python side: import tryit import ctypes b = bytearray(100) tryit.fun_voidp(b) # fail tryit.fun_voidp(ctypes.c_void_p.from_buffer(b)) # fail tryit.fun_voidp(ctypes.c_void_p.from_buffer(b).value) # fail i'd fix function prototype take char* , go last python line. there's no reason use void* in c++. understand if api does, shouldn't hard wrap own function.

i noticed relatively recend add h2o.ai suite, ability perform supplementary platt scaling improve calibration of output probabilities. (see calibrate_model in h2o manual .) nevertheless few guidance avaiable on online docs. in particular wonder whether when platt scaling enabled: how affects models' leaderboard? is, platt scaling calculated after ranking metric or before? how affects computing performance? can calibration_frame same validation_frame or should not (both under computation or theoretical point of view)? thanks in advance calibration post-processing step run after model finishes. therefore doesn't affect leaderboard , and has no effect on training metrics either. adds 2 more columns scored frame (with calibrated predictions). this article provides guidance how construct calibration frame: split dataset test , train split train set model training , calibration. it says: the important step create separate dataset perform calibration...
