The schema in this data file must match the datasource : Amazon Machine Learning -


when create model (regression) using amazon machine learning, provide datasource schema. data source contains values along target attribute. data source splitted in 70-30 training , evaluation of model , still need target attribute values in it. data used training first , evaluation target attribute required, understand.

now come batch prediction part. in have provide datasource , understand schema have similar schema used train model, again target attribute required why values required in part not understand. if provide dataset similar schema , no data in target attribute gives me 

 schema in data file must match datasource used create ml model ml-ksc8japcco0. ensure data file using matches schema structure.

when use same schema same model values in target attribute works fine.

you needs provide batch values make prediction less field predict; example,

i used structure make de model , training, select seconds_taken target

serial,operator,station,phase,next_phase,seconds 123,jack,machine 1,phase 1,phase 2,230528

the goal make prediction how many time gonna take pass first phase different values of operator , station, detect better performance on company.

select evaluation on machine learning dashboard

machine learning -> batch predictions -> create batch prediction

this structure make prediction:

serial,operator,station,phase,next_phase 123,benn,machine 1,phase 1,phase 2 123,jhon,machine 1,phase 1,phase 2 123,benn,machine 2,phase 1,phase 2 123,jhon,machine 2,phase 1,phase 2

take care on titles, got same error if use structure

serial,operator,station,phase,next_phase,seconds 123,benn,machine 1,phase 1,phase 2 123,jhon,machine 1,phase 1,phase 2 123,benn,machine 2,phase 1,phase 2 123,jhon,machine 2,phase 1,phase 2

apache - PHP Soap issue while content length is larger -

we have developed soap based webservice post data third party webservice. accepts 4 params. in 1 of parameters accepts xml string no size limit restriction put in place. the webservice works fine in local environment running on php 5.2 , apache2. works content length long 10 mb. in staging server running nginx , php fpm.we have updated max post size , max upload filesize in php.ini , client_max_body param in nginx.conf allow upto 50 mb. but webservice client keeps on loading in staging environment. gives 502 timeout , gives soap error. can me understand issue here?

asynchronous - Python asyncio task got bad yield -

i confused how play around asyncio module in python 3.4. have searching api search engine, , want each search request run either parallel, or asynchronously, don't have wait 1 search finish start another. here high-level searching api build objects raw search results. search engine using kind of asyncio mechanism, won't bother that. # no asyncio module used here class search(object): ... self.s = some_search_engine() ... def searching(self, *args, **kwargs): ret = {} # raw searching according args , kwargs , build wrapped results ... return ret to try async requests, wrote following test case test how can interact stuff asyncio module. # here testing script @asyncio.coroutine def handle(f, *args, **kwargs): r = yield f(*args, **kwargs) return r s = search() loop = asyncio.get_event_loop() loop.run_until_complete(handle(s.searching, arg1, arg2, ...)) loop.close() by running pytest, return runtimeerror: task got bad yield : {results s...

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
