正在获取\u pickle.UnpicklingError:运行craftassis代理时加载密钥“v”无效

Question

我正在尝试运行https://github.com/facebookresearch/craftassist，当运行代理时，我得到

  File "./python/craftassist/craftassist_agent.py", line 27, in <module>
    import memory
  File "/root/craftassist/python/craftassist/memory.py", line 23, in <module>
    import dance
  File "/root/craftassist/python/craftassist/dance.py", line 9, in <module>
    import tasks
  File "/root/craftassist/python/craftassist/tasks.py", line 18, in <module>
    from perception import ground_height
  File "/root/craftassist/python/craftassist/perception.py", line 24, in <module>
    BLOCK_DATA = minecraft_specs.get_block_data()
  File "/root/craftassist/python/craftassist/minecraft_specs.py", line 24, in get_block_data
    _BLOCK_DATA = _pickle_load("block_images/block_data")
  File "/root/craftassist/python/craftassist/minecraft_specs.py", line 68, in _pickle_load
    return pickle.load(f)
_pickle.UnpicklingError: invalid load key, 'v'

如何解决这个问题

谢谢
