Problem

I have a python application running using eventlet for serving requests. I also need to install anthropic, but it never settles with the application because of this async library "Anyio". Can't anthropic work without "Anyio" ? We can externally provide the asynchronous feature right ?

    I made it work by downgrading "AnyIO" to 3.7.0

    But now it creates another issue, it doesn't work with Celery now. Tried different versions but no luck.
