langchainrb VS pycall.rb

8. LangChain RB | Github | tutorial

So I hooked up the Ruby on Rails langchainrb gem (https://github.com/andreibondarev/langchainrb) and it seems like the approach is to store the plane text entries as meta data on pinecone. I definitely DO NOT want to do this as the data is private and secure on my own DB.

I would suggest taking a look at Langchain.rb as well. Disclosure: I'm the core maintainer.

Is the emerging architecture made out to be more complicated than what most of the companies are currently building? Perhaps! But this is most likely the general direction where things will start trending towards as the auxiliary ecosystem matures.

Shameless plug: For fellow Ruby-ists we're building an orchestration layer for building LLM applications, inspired by the original, Langchain.rb: https://github.com/andreibondarev/langchainrb

I'm the author of Langchain.rb.

@dliteful23 I loved your super detailed lessons-learned article! I'm the author of Langchain.rb, I would love to hear what you think of it if you get a chance to check it out. If there's anything that you'd like to see in the framework, please do let us know and we'll make sure to build it out if it aligns with the vision.

We’re building “Langchain for Ruby” under the current working name of “Langchain.rb”: https://github.com/andreibondarev/langchainrb

People that have contributed on the project thus far each have at least a decade of experience programming in Ruby. We’re trying our best to build an abstraction layer on top all of the common emerging AI/ML techniques, tools, and providers. We’re also focusbig on building an excellent developer experience that Ruby developers love and have gotten to expect.

Unlike the Python project, as it’s been pointed out here a countless number of times, we’d like to avoid deeply nested class structures that make it incredibly difficult to track and extend.

We’ve been pondering over the “what does Rails for Machine Learning look like?” question, and we’re taking a stab at answering this question.

We’re hyper-focused on the open source community and the developer community at large. All feedback/ideas/contributions/criticism are welcome and encouraged!

Yeah, I know there are few libraries that do similar things: pycall.rb and rb_call, and there is also rubypython, but it's not supported and doesn't work with Python 3. I used pycall to create matplotlib charts from Ruby, it's great, and I'm gonna use part of its code, type conversion implementation, for example. But I don't think it's enough, it's like a one way bridge, I want more, I want to call Python from Ruby and Ruby from Python at the same time: create an Airfow PythonOperator, invoke Ruby code inside, store some value into XCom. What about rb_call, I don't like how it's implemented at all, it starts a separate process and serializes data using MessagePack RPC, so you can't use callbacks. It's not even possible to pass a Python object as an argument or call Ruby method that requires a block. And of course it's not effective.

I have build a rails app that uses openai gem and it's working very well. For more advanced things I am exploring Pycall: https://github.com/mrkn/pycall.rb to call python functions. Don't have any experience though.

I have use this before cool and easy also could run in heroku ()( for my case https://github.com/mrkn/pycall.rb

From docs. I was able to install matplotlib (without --pre):

We use https://github.com/mrkn/pycall.rb extensively to interface with python libraries. So far, the only problem we have is memory leaks in python, but we mitigated the problem by isolating the leaking parts in a separate process.
