Denis Davydenko updated MXNET-1171:
-----------------------------------
Issue Type: Sub-task (was: Bug)
Parent: MXNET-731
> Refactor and Fix Memory Leak in FeedForward.scala
> -------------------------------------------------
>
> Key: MXNET-1171
> URL: https://issues.apache.org/jira/browse/MXNET-1171
> Project: Apache MXNet
> Issue Type: Sub-task
> Components: Apache MXNet Scala API
> Reporter: Naveen Swamy
> Priority: Major
>
> There is an active memory leak in FeedForward.scala's fit method, the public
> fit methods call initSymbolParams which in turn calls initParams, initParams
> allocates NDArrays for _argParams and _auxParams which get overwritten inside
> the private fit method.
> I have added TODO to fix this issue, creating this JIRA to move on to my
> story.
> Note that since the ND loses references, PhantomRef should pick up and clean
> when GC runs.
> // TODO: https://issues.apache.org/jira/browse/MXNET-1171
> // this leaks memory, initSymbolParams->initParams is already called which
> allocates
> // NDArray in argParams, auxParams and here we are overwriting it by calling
> again.
> // PhantomRef should take care of releasing this when GC is called, however
> we have to
> // wait for the GC call to happen
