jessebrizzi edited a comment on issue #10867: Scala Module API resize is leaking memory on the native size. URL: https://github.com/apache/incubator-mxnet/issues/10867#issuecomment-458329624 Updated https://github.com/jessebrizzi/MXNet-Bug to support testing with the released MXNet 1.3.1, 1.4.0-SNAPSHOT, and 1.5.0-SNAPSHOT The bug exists in 1.3.1 (this was already known), running https://github.com/jessebrizzi/MXNet-Bug/blob/master/scala/TestBug.scala for 10000 forward passes of random input resizes leads to over of 6gb of system memory used and climbing when using the GPU. Htop attributes the memory usage to the java/sbt process but JVMTop does not show this usage in the Heap inside the JVM (The default heapmax is not that large regardless). Both 1.4.0-SNAPSHOT and 1.5.0-SNAPSHOT cannot finish the 10000 forward passes random resize test as they crash/freeze as described in my previous comment. for all versions, the https://github.com/jessebrizzi/MXNet-Bug/blob/master/scala/TestNoBug.scala test runs fine with only 1.8ish GB of mem used on my machine (no random resizes on the input) for both GPU and CPU backed nets. The dockerfile/README in my bug repo https://github.com/jessebrizzi/MXNet-Bug has the needed instructions if someone wants to try and reproduce my observations.
