kice opened a new issue #11334: Cannot initializing parameters of SymbolBlock.
URL: https://github.com/apache/incubator-mxnet/issues/11334
 
 
   ref: https://discuss.mxnet.io/t/initializing-parameters-of-symbolblock/1213
   
   It looks like SymbolBlock will initializing all the parameters using the initializer given in the block.initialize() function, including bias, which cannot be initialized by Xavier. 
   
   Alought that [post](https://discuss.mxnet.io/t/initializing-parameters-of-symbolblock/1213) suggests a solution, and in addition, I think we should try to initialize the parameters if it was given in the symbol/json file.
   
   e.g. 
   `bias = mx.sym.Variable(name='conv_bias', shape=(num_filter,), init=mx.init.Zero())`
   or
   ```
   {
         "op": "null", 
         "name": "conv_bias", 
         "attrs": {
           "__init__": "[\"zero\", {}]", 
           "__shape__": "(64,)"
         }, 
         "inputs": []
   }
   ```
   
   Or if there a better way please let me know.
