Docker Notes Personal

-

 








Dockerfile


when you run an docker image, an instance is created, that is called as Docker Container







commands :


docker

docker pull image_name

docker run image_name


How to Create your own Docker image?


1. complete your python code, let's say app.py

2. make requirements.txt

3. Create 1 dockerfile in your project folder





It is compulsory to add 0.0.0.0 as host address, so that you can run it outside the docker as well





dockerhub username / the image name of your choice



8888 your port 

5000 flask app port inside docker


Finally, push it on docker hub

Extracting Tables and Text from Images Using Python

-
Image
In this blog, we'll explore a complete Python solution that detects and extracts tables and text from images using libraries like Transformers, OpenCV, PaddleOCR, and easyOCR. This step-by-step breakdown includes code to detect tables, extract content from individual table cells, and retrieve any remaining text in the image. Overview When working with scanned documents, such as invoices or forms, it is essential to accurately extract both structured information (like tables) and unstructured text. The approach we’ll explore uses Microsoft's pretrained object detection model to locate tables and OCR techniques to extract the text from both table cells and the rest of the image. Steps: 1. This code first detects table using microsoft's model. and save that image which contains detected table only  2. After that, from the detected table , we make a seperate image for each cell.  3. Then we read text from the image of each cell  4. Now, to read the extra texts except for the ...

Positional Encoding in Transformer

1. Why Position Matters in Transformers? Transformers rely on self‑attention, which processes tokens in parallel. This means, unlike RNNs, they don’t inherently know the order of words. So, sentences like “Ravi killed the lion” vs. “The lion killed Ravi” would look identical to a vanilla Transformer—clearly problematic! 🧪 Idea #1: The Naïve Approach A simple fix would be to add index/position of the token in an embedding vector. Issues: Unbounded values: Position IDs can become huge (e.g. 100,000+ in long texts), destabilizing training. Discrete steps: Sharp jumps between integers disrupt gradient flow. 🧪 Idea #2: Normalize the Position Numbers What if we divide the position numbers by a constant to make them small and smooth? That helps a bit—values don’t explode anymore. Issues: Now, if you observe, in both the sentences, the word at second position has got the different values. 1 for sentence1, and 0.5 for sentence2. so, the Neural network will get confused while training, what a...

Chain Component in LangChain

-
Image
LangChain is a powerful framework for building applications with Large Language Models (LLMs). One of its core features is the Chain Component , which allows developers to link multiple operations together to create complex workflows. In this blog, we'll explore different types of chains in LangChain and demonstrate their usage with code examples. 1️⃣ LLMChain (Basic Single-Step Chain) 🔹 Executes a single LLM call based on a prompt. 🔹 The simplest chain type. ✅ Use Case: When you need a single prompt-response from an LLM. Example: 2️⃣ SequentialChain (Step-by-Step Execution) 🔹 Executes multiple chains in sequence where each step depends on the output of the previous step. ✅ Use Case: Multi-step processes where each step depends on the previous output . 📌  Example: Blog Outline → Content Expansion → Summary Example: 3️⃣ SimpleSequentialChain (Basic Sequential Execution) 🔹 Similar to SequentialChain, but only passes the last step’s output forward (less flexible). 🔹 ...
