if timing >= max_d_datetime: TypeError: '>=' not supported between instances of 'datetime.datetime' and 'str'

这个错误通常是因为你在比较一个 `datetime.datetime` 类型的变量和一个字符串类型的变量。你需要将字符串类型的变量转换为 `datetime.datetime` 类型，然后再进行比较。

你可以使用 `datetime.datetime.strptime()` 函数将字符串转换为 `datetime.datetime` 类型。例如，假设你有一个字符串类型的变量 `max_d_datetime_str` 和一个 `datetime.datetime` 类型的变量 `timing`，你可以这样做：

import datetime

max_d_datetime_str = '2022-01-01 00:00:00'
max_d_datetime = datetime.datetime.strptime(max_d_datetime_str, '%Y-%m-%d %H:%M:%S')

timing = datetime.datetime.now()

if timing >= max_d_datetime:
    print("timing is later than or equal to max_d_datetime")
else:
    print("timing is earlier than max_d_datetime")

在这个例子中，`max_d_datetime_str` 会被转换为一个 `datetime.datetime` 类型的变量 `max_d_datetime`，然后将其与 `timing` 进行比较。

注意，这里使用了 `gevent` 库，需要先安装。可以在命令行中使用 `pip install gevent` 进行安装。
