any please.

when django asks "add default values create table", need create values resonate type of particular column.

your error apparent here: django.core.exceptions.validationerror: [u"'00:00:00' value has invalid format. must in yyyy-mm-dd hh:mm[:ss[.uuuuuu]][tz] format."]

the "random" values entered must in yyyy-mm-dd hh:mm[:ss[.uuuuuu]][tz] format.

remove datetimefields model, remigrate, , start over. time, when you're asked put in default values, put random 'datetime' (i.e. 2006-10-25 14:30:59).

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...
