Question

使用 .pkl 加载 pickle.load() 文件时引发了 TypeError。实际上，以前它是带有 Python 3.7 的工作文件，但现在我使用的是 Python 3.8.9

Python 3.8.9
cloudpickle==1.6.0
scikit-learn==0.20.2

片段 -

import pickle


with open('some_model.pkl', "rb") as f:
    pickle.load(f, **{"encoding": "latin1"})

异常-

TypeError: an integer is required (got type bytes)

pickle.load() - 类型错误：需要一个整数（得到类型字节）
