Pytorch load模型出错：_pickle.UnpicklingError: invalid load key, ‘＜‘.

在torch.load时候报错：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.7/dist-packages/torch/serialization.py", line 795, in load
    return _legacy_load(opened_file, map_location, pickle_module, **pickle_load_args)
  File "/usr/local/lib/python3.7/dist-packages/torch/serialization.py", line 1002, in _legacy_load
    magic_number = pickle_module.load(f, **pickle_load_args)
_pickle.UnpicklingError: invalid load key, '<'.

结论：模型文件损坏，检查模型大小（大概率没下载完整），重新（手动）下载。
