Hello @Gnavy! I'm Dosu, a friendly bot here to help you out. I can assist you in solving bugs, answer your questions, and guide you in contributing to our repository. While we're waiting for a human maintainer, I'm at your service. Now, let's take a look at this pickle problem of yours. Hang tight, and I'll get back to you with a full answer shortly!
seems like this is a queue in the RetrievalQA Obj
@Gnavy there is a lock in the object because of which it is not able to pickle.

It seems like you're encountering a pickling error when trying to use the RetrievalQA
component with Redis Cache. This is likely due to the fact that the RetrievalQA
object, or one of its attributes, is not serializable, which is a requirement for storing it in Redis Cache.
In Python, pickling is the process of converting a Python object into a byte stream, and unpickling is the inverse operation, whereby a byte stream is converted back into an object. Redis, being a key-value store, needs to convert the values (in this case, Python objects) into a format that can be stored and retrieved, which is where pickling comes in.
The RetrievalQA
component, as per the source code, seems to be a complex object with several attributes, some of which might not be serializable.
Unfortunately, without the specific error message, it's hard to pinpoint exactly which attribute is causing the issue. Could you please provide the exact error message you're seeing? This would help in identifying the non-serializable attribute and suggesting a possible workaround.
Also, please note that I'm unable to view the images you've attached as I can't process images. If there's any important information in those images, could you please provide it in text format?
For more information on pickling in Python, you can refer to the Python documentation on pickle.
For more information on how Redis handles Python objects, you can refer to the Redis documentation.
For more information on the RetrievalQA
component and Redis Cache in the langflow codebase, you can refer to the langflow repository.
I hope this helps! If you have any more questions, feel free to ask.
This response is meant to be useful and save you time. It is not meant to be a precise solution, but rather a starting point for your own research.
Help me be more useful! Please leave a π if this is helpful and π if it is irrelevant.

When use redis Cache,can't pickle RetrievalQA component.
so in this cause, we cant use the RetrievalQA,when we want use redis cache.
does anyone have idea?
