so came upon question asked list of unused account numbers. query wrote works, kind of hacky , relies on existence of table more records existing accounts: with tmp (select row_number() over( order cusno) custtable fetch first 999999 rows only) select tmp.a tmp not in (select cusno custtable) this works because customer numbers reused , there more records unique customer numbers. but, said, feels hacky , i'd generate temporary table 1 column , x records numbered 1 through x. looked @ recursive solutions, of looked way more involved solution wound using. there easier way doesn't rely on existing tables? i think simple answer no. able make determination of absence, platform needs know expected data set. can either generate temporary table or data set @ runtime - using method you've used (or variation thereof) - or can create reference table once, , compare against each ti

i mod , map creator , want work on mods @ multiple pcs. unfortuantely cloud syncing tools allow single folder (dropbox folder, googledrive folder), modding tools want files in specific location (e.g. ...documents/awesomecompany/awesomegame/mods or appdata/anothercompany/maps). i don't want move files around everytime, when finish working. preferably have git, can call git init in "...documents/awesomecompany/awesomegame/mods" , push/pull files whenever needed. well, why don't use git? because git not optimized binary files , if change files, repository grow needlessly large. enough me store recent version in cloud. have checked git annex, git media , git lfs, if understand correctly, add-on must installed on server? , honest, posts i've read, don't quite understand do, seems don't upload files except tell them to? , i'm not sure if keep 1 copy/history version of file? to sum up: there convenient way synchronize folders binary files @ arbitrar

i have autoencoder . model not important now. suppose model takes input image , output reconstructed image. after training, see effect of 1 tensor on output. in addition, images being fed autoencoder through fifoqueue . therefore, when running following peace of code: reconstructed_image = sess.run([deconv_image], feed_dict={mu:my_vector}) where deconv_image output tensor of model , mu hidden tensor inside model; automatically feed model image queue . my question is: value inside mu replaced whatever should come input image, or, takes vector fed using feed_dict argument. any appreciated!! when running final tensor, is, evaluating last tensor of graph, run tensors depends on. if have y3 operation depends on y2 , y2 depends on y1 , then, running final tensor in graph cause y1 run first, y2 evaluated after gets input y1 , finally, output of y2 feed y3 . graph follows: y1 -> y2 -> y3 on other hand, can run (evaluate) y3 feeding inputs directly us
