Langchain + Ollama Models GEN AI LLM Project

before you start this project you will need the following :

• Langchain API Key ( free to make)
• Downloading the dependencies
• Downloading LLAMA model im using llama 3.2
• streamlit tool

Notes 📝 : Sometimes you will have to keep downloading llama 3.2 so there is a file called llama.bat which will loop this process you may use it if things dont work with you

How can i can make my API key ?

First go to langchain account and press on setting

Then you will see the word API press on Create API button :

Make the purpose to be Personal

then you will get you key Copy it cause you will need it and i will show you how you can use your API Key NOTE ⚠️ API IS A SENSITIVE INFORMATION DONT SHARE IT WITH JUST ANYONE

Now how can i use my API key ?

first in you project folder you will create a Global file called .env ( which means you can access these keys regardless of the folders you have within the project )

it should look like this ( i have OPEN AI here cause i have a project that needs it ) OPEN AI API'S ARE PAID 5$ MINIMUM TO CONNECT

to ease downloading the dependencies that you would need add a text file with required dependencies and write

`pip intall textfilename.txt` 

i will put the file in the github as well

if the Ollama model doesnt wok that means in needs pulling use this command

ollama pull llama3.2

note that this will take time

now to run the app use this command

streamlit run app.py
