JSONReader: Missing field "backward_source_id"

[neophack]

My local package mxnet-cu80 (1.0.0), maybe It is not important, my OpSystem is win7 x64. Test model vgg16_ssd_512_voc0712_trainval.zip with problem as following:

C:\mxnet-ssd.cpp-win\build>ssd 000024.jpg -m ssd_512  -e 0
[08:58:48] D:\Dev\Projects\mxnet\dmlc-core\include\dmlc/logging.h:235: [08:58:48

d.count(it->first)) != (0) JSONReader: Missing field "backward_source_id"
 At  Line 10, around ^`, 

Also,I get no result in test model vgg16_reduced: C:\mxnet-ssd.cpp-win\build>ssd ..\demo\dog.jpg -m vgg16_reduced
