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 ``` [02:17:25] src/nnvm/legacy_json_util.cc:190: Loading symbol saved by previous version v1.0.1. Attempting to upgrade... [02:17:25] src/nnvm/legacy_json_util.cc:198: Symbol successfully upgraded! Traceback (most recent call last): File "/home/hypergroups/nutstore/ProjectsOnline/My/Python/MXNet/1.0/script/test_rgb.py", line 25, in <module> sym,arg_params, aux_params = mx.model.load_checkpoint(model_prefix,0) File "/home/hypergroups/anaconda2/lib/python2.7/site-packages/mxnet/model.py", line 425, in load_checkpoint tp, name = k.split(':', 1) ValueError: need more than 1 value to unpack ``` mxnet.__version__ is 1.1.0
