Hi all,

I've been compiling some gluoncv models and I noticed that the params size of 
the compiled model increases by a significant amount (1.5x) after optimizing, 
versus compiling without optimizing.  I'm just wondering why this is the case.

Concretely, for resnet18v2, if I just compile the model without any autotvm 
optimization, the compiled model has about 46MB params; if I do even just one 
iteration of optimization, the compiled model jumps to 77MB params.

I'm compiling for CUDA GPU.

See here for the example compiled models:
* http://people.mpi-sws.org/~jcmace/tvm/resnet18_v2_opt/tvm-model.json
* http://people.mpi-sws.org/~jcmace/tvm/resnet18_v2_noopt/tvm-model.json
* (for the .so and .params files, replace .json in the above URLs; this message 
board has a limit of 2 URLs per post)

Is this expected behavior?  Thanks in advance.

Jon
