   Hi @lanking520 again. After pulling your changes for the fix of my issue, I tried it right away but am having now a strange error using the example of **ObjectDetection.java** class but I made some alteration to it to meet my requirements. Now it looks like this:
   https://gist.github.com/androuino/7808b6fdf05e3122a03f35c63d3a5f89
   
   I followed the step by step tutorial here https://github.com/apache/incubator-mxnet/tree/master/scala-package/mxnet-demo/java-demo for running the demo.
   
   **and this is the error am having:**
   
   `SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
   SLF4J: Defaulting to no-operation (NOP) logger implementation
   SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

   The image I was used to test is **512x512** in size and the model that I've trained is also set to **512**.
   
   Thanks for any enlightenment that you could give me with this error or at least tell me if I did something or missed something with the code: https://gist.github.com/androuino/7808b6fdf05e3122a03f35c63d3a5f89 .
