Importing libraries and loading surroundings variables

This step includes configuring the important libraries required for the applying, together with machine studying and NLP frameworks. We will even load surroundings variables to securely handle API keys, credentials, and configuration settings required all through the event course of.

import os
import validators
import streamlit as st
from langchain.prompts import PromptTemplate
from langchain_groq import ChatGroq
from langchain.chains.summarize import load_summarize_chain
from langchain_community.document_loaders import UnstructuredURLLoader
from yt_dlp import YoutubeDL
from dotenv import load_dotenv
from langchain.schema import Doc
load_dotenv()
groq_api_key = os.getenv("GROQ_API_KEY")

This part imports libraries and masses the API key from an .env file, which retains delicate data corresponding to API keys secure.

Designing the frontend with Streamlit

On this step, we’ll create an interactive and easy-to-use interface for the applying utilizing Streamlit. This contains including enter kinds, buttons, and displaying outcomes, permitting customers to seamlessly work together with backend functionalities.

st.set_page_config(page_title="LangChain Enhanced Summarizer", page_icon="🌟")
st.title("YouTube or Web site Summarizer")
st.write("Welcome! Summarize content material from YouTube movies or web sites in a extra detailed method.")
st.sidebar.title("About This App")
st.sidebar.data(
    "This app makes use of LangChain and the Llama 3.2 mannequin from Groq API to offer detailed summaries. "
    "Merely enter a URL (YouTube or web site) and get a concise abstract!"
)
st.header("Find out how to Use:")
st.write("1. Enter the URL of a YouTube video or web site you want to summarize.")
st.write("2. Click on **Summarize** to get an in depth abstract.")
st.write("3. Benefit from the outcomes!")

These strains set the web page settings, title, and welcome textual content for the principle person interface of the applying.

Textual content enter for URL and mannequin loading

Right here, we’ll arrange a textual content enter subject the place customers can enter a URL to investigate. Moreover, we’ll combine the required mannequin loading performance to make sure that the applying can course of the URL effectively and apply the machine studying mannequin as wanted for evaluation.

st.subheader("Enter the URL:")
generic_url = st.text_input("URL", label_visibility="collapsed", placeholder="https://instance.com")

Customers can enter the URL (YouTube or web site) they wish to summarize in a textual content entry subject.

llm = ChatGroq(mannequin="llama-3.2-11b-text-preview", groq_api_key=groq_api_key)
prompt_template = """
Present an in depth abstract of the next content material in 300 phrases:
Content material: {textual content}
"""
immediate = PromptTemplate(template=prompt_template, input_variables=("textual content"))

The mannequin makes use of a message template to generate a 300-word abstract of the supplied content material. This template is included into the abstract chain to information the method.

Definition of operate for importing YouTube content material

On this step, we’ll outline a operate that’s chargeable for looking out and loading YouTube content material. This characteristic will take the supplied URL, extract related video knowledge, and put together it for evaluation utilizing the in-app machine studying mannequin.

def load_youtube_content(url):
    ydl_opts = {'format': 'bestaudio/greatest', 'quiet': True}
    with YoutubeDL(ydl_opts) as ydl:
        data = ydl.extract_info(url, obtain=False)
        title = data.get("title", "Video")
        description = data.get("description", "No description accessible.")
        return f"{title}nn{description}"

This operate makes use of yt_dlp to extract data from YouTube video with out downloading it. Returns the title and outline of the video, which might be summarized by the LLM.

Dealing with abstract logic

if st.button("Summarize"):
    if not generic_url.strip():
        st.error("Please present a URL to proceed.")
    elif not validators.url(generic_url):
        st.error("Please enter a legitimate URL (YouTube or web site).")
    else:
        attempt:
            with st.spinner("Processing..."):
                # Load content material from URL
                if "youtube.com" in generic_url:
                    # Load YouTube content material as a string
                    text_content = load_youtube_content(generic_url)
                    docs = (Doc(page_content=text_content))
                else:
                    loader = UnstructuredURLLoader(
                        urls=(generic_url),
                        ssl_verify=False,
                        headers={"Person-Agent": "Mozilla/5.0"}
                    )
                    docs = loader.load()

                # Summarize utilizing LangChain
                chain = load_summarize_chain(llm, chain_type="stuff", immediate=immediate)
                output_summary = chain.run(docs)

                st.subheader("Detailed Abstract:")
                st.success(output_summary)

        besides Exception as e:
            st.exception(f"Exception occurred: {e}")

• If it is a YouTube hyperlink, load_youtube_content extracts the content material, wraps it in a doc, and shops it in paperwork.
• If it’s a web site, UnstructuredURLLoader retrieves the content material as paperwork.

Operating the abstract string: The LangChain abstract chain processes the uploaded content material and makes use of the request template and LLM to generate a abstract.

To provide your app a classy look and supply important data, we’ll add a customized footer utilizing Streamlit. This footer can show necessary hyperlinks, thank yous or contact particulars, making certain a clear {and professional} person interface.

st.sidebar.header("Options Coming Quickly")
st.sidebar.write("- Choice to obtain summaries")
st.sidebar.write("- Language choice for summaries")
st.sidebar.write("- Abstract size customization")
st.sidebar.write("- Integration with different content material platforms")

st.sidebar.markdown("---")
st.sidebar.write("Developed with ❤️ by Gourav Lohar")
