Importing Libraries and Loading Atmosphere Variables

This step entails organising the important libraries wanted for the app, together with any machine studying and NLP frameworks. We’ll additionally 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 import Libraries and masses the API key from an .env file, which retains delicate info like API keys safe.

Designing the Frontend with Streamlit

On this step, we’ll create an interactive and user-friendly interface for the app utilizing Streamlit. This contains including enter varieties, buttons, and displaying outputs, permitting customers to seamlessly work together with the 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.information(
    "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 traces set the web page configuration, title, and welcome textual content for the principle UI of the app.

Textual content Enter for URL and Mannequin Loading

Right here, we’ll arrange a textual content enter discipline the place customers can enter a URL to research. Moreover, we’ll combine the required mannequin loading performance to make sure that the app 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 need summarized in a textual content enter discipline.

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=["text"])

The mannequin makes use of a immediate template to generate a 300-word abstract of the offered content material. This template is integrated into the summarization chain to information the method.

Defining Operate to Load YouTube Content material

On this step, we’ll outline a perform that handles fetching and loading content material from YouTube. This perform will take the offered URL, extract related video information, and put together it for evaluation by the machine studying mannequin built-in into the app.

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

This perform makes use of yt_dlp to extract YouTube video info with out downloading it. It returns the video’s title and outline, which can be summarized by the LLM.

Dealing with the Summarization 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 = [Document(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’s a YouTube hyperlink, load_youtube_content extracts the content material, wraps it in a Doc, and shops it in docs.
• If it’s an internet site, UnstructuredURLLoader fetches the content material as docs.

Operating the Summarization Chain: The LangChain summarization chain processes the loaded content material, utilizing the immediate template and LLM to generate a abstract.

To provide your app a cultured look and supply important info, we’ll add a customized footer utilizing Streamlit. This footer can show essential hyperlinks, acknowledgments, or contact particulars, making certain a clear {and professional} consumer 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")
