+        return _configure(cls, inheritable_callbacks, local_callbacks, verbose)
+
+
+T = TypeVar("T", CallbackManager, AsyncCallbackManager)


Can think of a better way to do this if it's ugly -- basically want to enforce with typing that typing among arguments and return value must be consistent

Makes sense to me

docs/ecosystem/gpt4all.md

 # There are many CallbackHandlers supported, such as
 # from langchain.callbacks.streamlit import StreamlitCallbackHandler

 callback_manager = CallbackManager([StreamingStdOutCallbackHandler()])
-model = GPT4All(model="./models/gpt4all-model.bin", n_ctx=512, n_threads=8, callback_handler=callback_handler, verbose=True)
+model = GPT4All(model="./models/gpt4all-model.bin", n_ctx=512, n_threads=8, callback_handler=callback_handler,


Was this line wrong anyway? In the previous line creating a callback_manager, then passing a callback_handler var (that I think doesn't exist) to a callback_handler arg that I also think doesn't exist

oh yeah, this was messed up by the pycharm refactoring tool

+            self.add_handler(handler, inherit=inherit)

is this method useful enough to exist?

+        run_id: Optional[str] = None,

We don't have these kwargs in js, should we?

+        else:
+            callback_manager = inheritable_callbacks
+        callback_manager = copy.deepcopy(callback_manager)


why call deep copy directly here rather than the copy method?

Indeed, I ran into this. What's the logic behind a copy here anyway? I'd assume many callback managers—definitely mine—maintain state that cannot be copied such as file handles, network connections, asyncio.Futures etc.

I don't know this code that well, but why even copy at all? It seems somewhat antithetical to the rationale of a callback manager that everything makes a copy of it.

(Not only speaking of the copying of the callback_manager but also all handlers few lines below.)

@agola11 This was a breaking change. Is it documented somewhere how to migrate? In my case, I did the following:

from langchain.callbacks.base import AsyncCallbackManager

and replaced it with:

from langchain.callbacks.manager import AsyncCallbackManager

but it broke my app:

Help 😁

@pors -- can you send me a snipped of how you were using AsyncCallbackManager and what handlers you were using along with it? I'll be able to help you more

pors · 2023-05-02T17:58:35Z

@agola11 The whole project is here: https://github.com/pors/langchain-chat-websockets/blob/main/query_data.py

The relevant code is largely based on https://github.com/hwchase17/chat-langchain, so the issue may also be there.

agola11 · 2023-05-02T17:59:43Z

@pors okay thanks. Looking in a bit

agola11 · 2023-05-02T19:55:50Z

Once this lands, your issue should be resolved: #3995 -- please comment if that's not the case

pors · 2023-05-03T06:04:54Z

Thanks! It works again for me. I like the fast release schedule :)
