Question

用python3运行python2如下代码提示Traceback (most recent call last)是什么原因？如何解决？

Traceback (most recent call last):

video, result = predict(sys.argv[1], sys.argv[2])

TypeError: a bytes-like object is required, not 'str'

Answer 1

类型错误：需要类似对象的字节，而不是'str'
python3 和 python2 是不兼容的
虽然有很多地方相同 但是直接用来运行不同版本的代码 很大概率是会出问题的
