HyperGroups opened a new issue #10998: Question: problem with import model generated by Wolfram Mathematica?
URL: https://github.com/apache/incubator-mxnet/issues/10998
 
 
   When I'm using load_checkpoint()
   I found the code in model.py is
     ```
   symbol = sym.load('%s-symbol.json' % prefix)
       save_dict = nd.load('%s-%04d.params' % (prefix, epoch))
       arg_params = {}
       aux_params = {}
       for k, v in save_dict.items():
        tp,name = k.split(':', 1)
               if tp == 'arg':
                   arg_params[name] = v
               if tp == 'aux':
                   aux_params[name] = v
   ```
   
   the problem is in my arguments, there is no {{{___colon : ____]}}
   
   so the error info is
   ```
