我有一个问题时，从pytube模块下载视频，我尝试更新pytube，再次下载，仍然不工作，我使用的是python 3.11，这是我的代码：
'定义进程函数（流，块，剩余字节）：打印（“下载”）def完成函数（流，文件路径）：print（“下载完成”）messagebox.showinfo（title=“下载完成”，message=“视频下载成功”）
def下载（）：用户输入=字符串（链接.get（））yt = YouTube（用户输入，进度回调=进度函数，完成回调=完成函数）打印（yt.标题）打印（yt.缩略图url）视频= yt.流.get_highest_resolution（）video.download（）'
这就是错误所在：
