PyScript中使用Panel时遭遇系列错误的排查求助

我之前用PyScript搭配Panel写的脚本正常跑了快一年，最近突然罢工了，折腾了好几个阶段还是没完全解决，想请大家帮忙看看问题出在哪。

初始错误：AttributeError 找不到'initialized'属性 #

一开始我遇到的是这个报错，完全摸不着头脑，所以一开始根本不知道该怎么下手修复：

第一次更新：升级PyScript后遇到顶级await禁用问题 #

后来我把PyScript升级到了最新版本，报错变了，这次看起来更具体，但我完全不懂什么是协程：

UserError: (PY9000): The use of top-level "await", "async for", and "async with" has been removed.
Please write a coroutine containing your code and schedule it using asyncio.ensure_future() or similar.

第二次更新：尝试协程后遇到Panel模块找不到的问题 #

我照着提示试着写了个协程，结果又弹出新错误：

No module named 'panel'

现在我大概明白过来，这个脚本是PyScript还在Beta阶段时写的，当时的示例代码和现在的规范已经不一样了，我打算照着现在的官方示例重新写一遍脚本，但还是希望能得到大家的指点，看看有没有更快捷的修复方式，或者这些错误到底是版本不兼容导致的还是别的问题？
