partial_fc error : segmentation fault:11

hi, I tried partial_fc for training. As installed the same version of the requests and set the same settings in default.py, I got the segmentation fault:11. I used emore for training.
The error occured in _arg_params_rank_0 = self.broadcast_parameters(_arg_params)
https://github.com/deepinsight/insightface/blob/master/recognition/partial_fc/mxnet/memory_module.py#L68.
Hope for any suggestions.

Start by reproducing the partial_fc training setup described in the issue, including the settings in default.py and the emore dataset. Inspect recognition/partial_fc/mxnet/memory_module.py at line 68, where broadcast_parameters is reported to fail, and determine whether the segmentation fault can be reproduced. Done means identifying a reproducible cause or documenting the missing environment details needed to proceed.
