   @Roshrini 
   
   The results are always exactly the same after setting the seed values.
   
   I triggered the CI (uncomment the line in `.travis.yml` file) for the 
converter and it can pass the tests with both the original seeds and the new 
seeds. Therefore it is __not necessary__ to change the seed values to pass the 
CI tasks.
   
   Besides, I've done some calculations manually for convolution and batch 
normalization, and the results are the same as mxnet's outputs. However, there 
are always some slight differences between coreml's outputs and mxnet's outputs 
in my machine. I think there may be some environmental differences and the new 
seeds are more compatible with different versions.
   
   In summary, currently all tests could pass the CI tasks and I can change 
back the seed values if it is insisted.
