使用泡菜检索保存的对象时出错

Question

使用基于 MESA 代理的建模包。使用 pickle 保存我的中间模型的状态。但是当检索保存的模型时，执行以错误告终：

  File "/home/demonwolf/PycharmProjects/pythonProject1/main.py", line 281, in <module>
    empty_model = pickle.load(f)
  File "/home/demonwolf/anaconda3/envs/ABM/lib/python3.7/codecs.py", line 322, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 0: invalid start byte```



Any help would be appreciated.
Thanks in advance.

文件（pickle.load(f)中的f参数）应该以二进制读取（rb）模式打开，而不是默认的文本（r）模式。

with open("path/to/your/pickle.bin", "rb") as f:
    empty_model = pickle.load(f)
