This creates problems if we expect these to differ (ex. no mini-batch training where the batch size is the number of records)."},"comment":{"url":"https://api.github.com/repos/NervanaSystems/neon/issues/comments/118756077","html_url":"https://github.com/NervanaSystems/neon/issues/6#issuecomment-118756077","issue_url":"https://api.github.com/repos/NervanaSystems/neon/issues/6","id":118756077,"user":{"login":"scttl","id":30309,"avatar_url":"https://avatars.githubusercontent.com/u/30309?v=3","gravatar_id":"","url":"https://api.github.com/users/scttl","html_url":"https://github.com/scttl","followers_url":"https://api.github.com/users/scttl/followers","following_url":"https://api.github.com/users/scttl/following{/other_user}","gists_url":"https://api.github.com/users/scttl/gists{/gist_id}","starred_url":"https://api.github.com/users/scttl/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/scttl/subscriptions","organizations_url":"https://api.github.com/users/scttl/orgs","repos_url":"https://api.github.com/users/scttl/repos","events_url":"https://api.github.com/users/scttl/events{/privacy}","received_events_url":"https://api.github.com/users/scttl/received_events","type":"User","site_admin":false},"created_at":"2015-07-06T07:29:37Z","updated_at":"2015-07-06T07:29:37Z","body":"As batch_size is no longer stored as part of model parameters, we are successfully able to train a model with one batch size, save it, load it, then use it to generate predictions of a different batch_size."}}
