Finally! A great explanation how the vector store works in LangFlow 😅

Great series thus far Leon, I like the look and the fact its Python. I hope you go all the way with this series.

Thanks man! Anything you would like me to cover?

@@leonvanzyl Agent Teams definately also, would love to know the strengths and weaknesses or a comparison between flowise and langflow. They both seem awesome. I guess ultimately it will be "horses for course" depending on your needs

Another great video, thanks, Leon! Does Langflow support images as input and output generated images?

@julienechavidre6389 Ай бұрын

Thanks a lot Leon for your video series. It helps a lot. Is there a way to have a video to produce simple code files (like JSON), based on "code samples" (probably stored in a vector store)?

A simple text based rag application is explained at various places but there is no explanation if we can create a multimodal RAG application with either Langflow or with Flowise. Is it possible to get an example showing the usage of images in both input as well as output?

@FacadeEngineering Ай бұрын

Thanks. Can you also make video on html output of langflow? It is not working great like flowwise. Also how to make embedding on database trouth api and customizing components are great topics

Hi, I'm deciding which tool to learn to start my journey, but in the last few days, I've been switching between Flowise and Langflow with double effort. Checking also Vextorshift. I like a lot Langflow for the style and the fact that it is "already online" with the new v1. Which platform do you suggest to study and use? Thank you (thanks for all the videos!) Are you continuing the series on Langflow? And on Flowise & VectorShift?

@4pass115 Ай бұрын

Sorry if the question seems simple, I'm not a programmer. After finishing the assistant/chat, how do I make it stay online. Do I need to store it on a server? Do you have a video showing this step? Even in flowise, you install it on the website, but if you don't access it from the computer where the "node" and flowise were installed, it gives an error.

Is there any way to extract images from the knowledge base documents and retrieve them later in the output ?

Hello Leon, how can we control sessionid, when exporting flowise workflow via API, in Telegram bot, so it can have unique session id with each user id? Thanks in advance ❤

My vector search gives this error for some reason "ValueError: Error building Component Pinecone Search: Invalid inputs provided." any idea why?

@jankotyza8146 12 күн бұрын

Hi, The video is well-made, but I'm having trouble getting it to work with Chroma or Pinecone. It seems that Langflow has changed since the video was made. For starters, there is no "Vector search" menu as mentioned, only "Vector Stores." Additionally, both Chroma (now Chroma DB) and Pinecone have different connection points on the right side compared to the video. There are now Retriever, Search Results, and Vector Store connection points, none of which can be connected to the "context" variable on the Prompt node. As a result, I'm stuck halfway through. Perhaps the video is outdated and could use a revision? Thanks!

@leonvanzyl 12 күн бұрын

Yeah, super frustrating for us creators when the platform changes just about everything with each release 😂.

@professions_ Ай бұрын

A question about Chroma please. Can I add different types of data files (pdf, doc, json) using the Chroma local storage option, or will it overwrite the data?

@leonvanzyl Ай бұрын

Yes, you can add multiple files (and different file types). The content is ADDED to the vector store.

Compare Flowise what's advantage of Langflow

@doctordude5728 Ай бұрын

I don't have a section called "core components" so I am missing "Inputs, Outputs, Data, Models.." actually everything except "Vector Stores" and "Embeddings". What I've got are only the components that you have under the section "Extended"! So how can I get all the other components that I need to create a RAG Chatbot? Can you explain that please?

@leonvanzyl Ай бұрын

You need to install the pre release version of Langflow. Check out my Getting Started video for installation instructions 👍

Apologies if I already ask this personal preference FW or LF? Do you know if LF have more features and control than FW? I have not use LF but would like To give it a go if it is better than FW in terms of features etc. would appreciate you own personal opinion thx 🙏

I think Langflow has potential, but they're not as advanced as Flowise.
