xgboost - xboost dmlc-submit eats command quotes (needed to run python job via scl enable) -

-

i use redhat 6.8 yarn cluster nodes, , uses python 2.6.6. in order python 2.7 in redhat 1 uses software collections. activate software collection 1 must scl enable. print python version example 1 scl enable python27 'python -v'

problem when try submit python job yarn follows

dmlc-submit --cluster=yarn scl enable python27 'python -v'

it seems eat quotes , produces error (instead of expected python 2.7.8):

unable open /etc/scl/prefixes/python!

that same output 1 gets when doing following @ bash prompt on machine

scl enable python27 python -v

i'm trying figure out how fool argparse letting through.

looked argparser (which dmlc-core , xgboost use) source code trying figure out possible escaping mechanism. couldn't find did find out dmlc-submit picks job submission node environment , recreates on each of execution nodes. looked @ scl enable , /opt/rh/python27/enable script , realized ld_library_path important one. path reason doesn't carry on specify full path scl provided python27

following happily runs on yarn 2.7.1 cluster

cd xgboost dmlc-core/tracker/dmlc-submit --cluster=yarn --num-workers=9 --worker-cores=4 /opt/rh/python27/root/usr/bin/python tests/distributed/test_basic.py

i have postgresql db number of tables. if query: select column_name information_schema.columns table_name="my_table"; i list of columns returned properly. however, when query: select * "my_table"; i error: (programmingerror) relation "my_table" not exist 'select *\n "my_table"\n' {} any thoughts on why can columns, can't query table? goal able query table. you have include schema if isnt public one select * <schema>."my_table" or can change default schema show search_path; set search_path my_schema; check table schema here select * information_schema.columns for example if table on default schema public both works ok select * parroquias_region select * public.parroquias_region but sectors need specify schema select * map_update.sectores_point

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
