When i train my data, just **one** class,  i have already changed the filters=3*(class num+5)=18 in yolov3.cfg file.  But the loss value is around 27 and does not continue to fall. The val loss always =nan, and the generated model does not detect the results.  i am confused --"},"comment":{"url":"https://api.github.com/repos/qqwweee/keras-yolo3/issues/comments/393790410","html_url":"https://github.com/qqwweee/keras-yolo3/issues/70#issuecomment-393790410","issue_url":"https://api.github.com/repos/qqwweee/keras-yolo3/issues/70","id":393790410,"node_id":"MDEyOklzc3VlQ29tbWVudDM5Mzc5MDQxMA==","user":{"login":"elcronos","id":9023043,"node_id":"MDQ6VXNlcjkwMjMwNDM=","avatar_url":"https://avatars1.githubusercontent.com/u/9023043?v=4","gravatar_id":"","url":"https://api.github.com/users/elcronos","html_url":"https://github.com/elcronos","followers_url":"https://api.github.com/users/elcronos/followers","following_url":"https://api.github.com/users/elcronos/following{/other_user}","gists_url":"https://api.github.com/users/elcronos/gists{/gist_id}","starred_url":"https://api.github.com/users/elcronos/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/elcronos/subscriptions","organizations_url":"https://api.github.com/users/elcronos/orgs","repos_url":"https://api.github.com/users/elcronos/repos","events_url":"https://api.github.com/users/elcronos/events{/privacy}","received_events_url":"https://api.github.com/users/elcronos/received_events","type":"User","site_admin":false},"created_at":"2018-06-01T07:26:43Z","updated_at":"2018-06-01T07:26:43Z","author_association":"NONE","body":"Hey guys so just to clarify in your case, after how many epochs you start getting a loss different than nan?\r\n\r\nI first tried and stopped after 5 epochs. Then I changed to 100. I just wanted to know how many epochs you will start getting some results !\r\n\r\n<img width=\"1539\" alt=\"screen shot 2018-06-01 at 2 08 37 pm\" src=\"https://user-images.githubusercontent.com/9023043/40827380-01cdacf2-65b0-11e8-81c4-3edcc9ce5a03.png\">\r\n"}}
