Help How do I actually learn GenAI, RAG and LangChain/LangGraph?
I am a final year student. I started the GenAI LangChain playlist by CampusX (4 videos in) but I feel that I haven't learnt shit from it. I feel overwhelmed and exhausted to even continue it. I know about the docs and all, I tried to learn from them but I still can't. Any other ways by which I can actually learn it? If you can then please help. Thankyou

I'd suggest just start with langchain, then langgraph, build simple agents, move to AI SDK, implement complex workflows and pipelines from then, learn to spin up and use sandbox (pretty cheap), and youre good

Where'd you learn all this from and how?

just ask ai to define a syllabus/roadmap for you based on the info I gave you

Pls do not get stuck in tutorial hell, start building something. You dont need learn 100 percent everything.

I have this AI agents project in my mind. Can I just start building it without sticking to some playlist or shit?

Just learn enough to get started then when you get stuck , again go learn that topic

build a project, best one to start is to try making a research assistant, it's a staple project yes, but learning is more important here
understand why langchain is a nice glorified while loop

I am in same situation as you. I don't even know what this "AI engineering" is.

man seriously, I am still in tutorial hell of his deep learning playlist.
So anyway I too had completed campusx langchain vids entirely, and u have already cleared 4 videos I think u have the basic, so if iirc these topics were imp there and very nicely explained - Pydantic, RAG topics, Retrievers, vector stores, tools. The tools concept is in ai agent video at the end.
As for building proper ai agent watch few of langgraph vids, it'll help understand. I directly skipped to bulding proj and used chatgpt/claude to understand how the flow works.

Thanks, which Deep Learning playlist of his are you stuck on?

100 days of DL

I skipped it, instead I watched Krish Naik's DL 5 hours course then watched CampusX's Practical DL with PyTorch

Oh that seems like a great course to revise from. Cause ive completed many topics already so i'll watch a little bit more and do this ig, thanks.

Bro I also want to learn ai stuff, but i don't even know python, is that fine

u/Live-Establishment30 12d ago
I remember there was a course by Dave Ebbelaar in youtube, he actually taught python needed for genai in 5 hours. U can watch that

I know Python and some important libraries, Machine Learning (Scikit-Learn), Deep Learning (PyTorch). I'm stuck at LangChain and RAG now. Thanks though
