RuntimeError: Error(s) in loading state_dict for DataParallel

model.load_state_dict(state_dict, strict=True)

Copies parameters and buffers from :attr:state_dict into this module and its descendants. If :attr:strict is True, then the keys of :attr:state_dict must exactly match the keys returned by this module’s :meth:~torch.nn.Module.state_dict function
 state_dict 。 strict True, state_dict keys keys 。 False, 。

Arguments:
state_dict (dict): a dict containing parameters and persistent buffers.
strict (bool, optional): whether to strictly enforce that the keys in :attr:state_dict match the keys returned by this module’s:meth:~torch.nn.Module.state_dict function. Default: True
