ruby on rails 4 - heroku run rake db:migrate Error connecting to dyno -

-

i new on ruby on rails. , trying deploy application local system heroku, when run heroku run rake db:migrate, error msg: running rake db:migrate attached terminal... up, run.7855 !
! error connecting dyno, see https://devcenter.heroku.com/articles/one-off-dynos#timeout-awaiting-process

i've followed link site didn't understand said there. please how deploy appreciated. thank you

seems have no access rendezvous.runtime.heroku.com:5000

ask system administrators or internet service provider allow address , port you

this problem solution described @ https://devcenter.heroku.com/articles/one-off-dynos#timeout-awaiting-process, didn't understand @ once :)

you can check access necessary resource telnet rendezvous.runtime.heroku.com 5000 command

update: encountered problem when rendezvous.runtime.heroku.com:5000 accessible heroku run ... command doesn't work. in case command must modified heroku run:detached ...

it helped me, interactive utilities bash not work because of output available in logs

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor

i used nvidia sdk bitonic sort , works great me. 32 bits (uint) need ulong keys. have typically 2^14 keys @ time , power of 2. searched on not find kernel designed ulong. i tried modified nvidia sdk bitonic sort using ulong keys not work. kernel not crash after de call clenqueuendrangekernel got error : cl_invalid_command_queue can tell me how modify bitonic sort or radixsort, or can sort ulong keys? i running nvidia quadro 4000 opencl 1.1 cuda 6.5.20 full_profile used original nvidia sdk bitonicsort.cl i used"ulong" keys , value input , ouput instead of "uint" thanks helping i made work-around suit need. used 30 bits of key , 18 high bits of value sorting. changed comparators (2 lines): '#define mask 0xffffc000 // suit need from this: if( (*keya > *keyb) == dir ) this: if(((*keya > *keyb)||((*keya == *keyb)&&((*vala & mask)> (*valb & mask)))) == dir ) it works fine. but, still, it's work-a
