python - Can xgboost.DMatrix be silent by set "silent=True" -


i learning xgboost. want finish demonstration xgboost python api. when use function "xgboost.dmatrix" data set file,silent set true. however, function "xgboost.dmatrix" output message "[23:28:44] 1441x10 matrix 11528 entries loaded file_name". setting error parameters? reference

this interesting. silent value taken , passed wrapper, seems wrapper doesn't use !

this shows appropriate code https://github.com/dmlc/xgboost/blob/master/src/c_api/c_api.cc#l202

which says:

int xgdmatrixcreatefromfile(const char *fname,                             int silent,                             dmatrixhandle *out) {   api_begin();   if (rabit::isdistributed()) {     log(console) << "xgboost distributed mode detected, "                  << "will split data among workers";   }   *out = new std::shared_ptr<dmatrix>(dmatrix::load(fname, false, true));   api_end(); }

i.e. though silent argument, not used in function anywhere ... (very weird)

so, seems right now, if you're using of wrappers (python, r, julia, etc) silent functionality dmatrix won't work.
