After looking at the logfile, it looks like logs of some of the operations are duplicated i.e. it looks like some of the operations in the graph are ran multiple times over the single run of the complete graph. For example, Operation \"gradients/conv2/Conv2D_grad/Conv2DBackpropFilter\" (link to logfile : https://gist.github.com/xilenteyex/d54305e0448e1aa3d878872c45b8ed3a#file-timeline-1-json-L2270) is logged multiple times. Is this some sort of bug or am I missing something? \r\n\r\nThanks a lot for looking into this issue!  \r\n\r\n\r\n### Source code / logs\r\ncifar10 example : https://github.com/tensorflow/models/tree/master/tutorials/image/cifar10\r\nhere is a the link to my modified version of cifar10_train.py in which I added logging : \r\nhttps://gist.github.com/xilenteyex/b6fab3a5abdb65bf674aa7d0a4ec4b5c\r\none of the sample log files is : https://gist.github.com/xilenteyex/d54305e0448e1aa3d878872c45b8ed3a\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/tensorflow/tensorflow/issues/comments/411750635","html_url":"https://github.com/tensorflow/tensorflow/issues/17910#issuecomment-411750635","issue_url":"https://api.github.com/repos/tensorflow/tensorflow/issues/17910","id":411750635,"node_id":"MDEyOklzc3VlQ29tbWVudDQxMTc1MDYzNQ==","user":{"login":"tensorflowbutler","id":28546240,"node_id":"MDQ6VXNlcjI4NTQ2MjQw","avatar_url":"https://avatars2.githubusercontent.com/u/28546240?v=4","gravatar_id":"","url":"https://api.github.com/users/tensorflowbutler","html_url":"https://github.com/tensorflowbutler","followers_url":"https://api.github.com/users/tensorflowbutler/followers","following_url":"https://api.github.com/users/tensorflowbutler/following{/other_user}","gists_url":"https://api.github.com/users/tensorflowbutler/gists{/gist_id}","starred_url":"https://api.github.com/users/tensorflowbutler/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/tensorflowbutler/subscriptions","organizations_url":"https://api.github.com/users/tensorflowbutler/orgs","repos_url":"https://api.github.com/users/tensorflowbutler/repos","events_url":"https://api.github.com/users/tensorflowbutler/events{/privacy}","received_events_url":"https://api.github.com/users/tensorflowbutler/received_events","type":"User","site_admin":false},"created_at":"2018-08-09T13:06:20Z","updated_at":"2018-08-09T13:06:20Z","author_association":"MEMBER","body":"Nagging Assignee @prb12: It has been 105 days with no activity and this issue has an assignee.
