err: Pickle Machine failed on opcode:0x81. Stack size:1. Memo size:0. Cause:Input encountered opcode that is not implemented

i need unpickle an instance of a Python object with golang now, can you help me fix it out?

If you can provide example python code that generates a pickled object containing this byte code I may be able to help.
