+# End to End Tutorial on using Llama models for Multi-Modal RAG 
+
+## Recipe Overview: Multi-Modal RAG using `Llama-3.2-11B` model: 
+
+This is a complete workshop on labelling images using the new Llama 3.2-Vision Models and performing RAG using the image caption capiblites of the model.
+
+- **Data Labeling and Preparation:** We start by downloading 5000 images of clothing items and labeling them using `Llama-3.2-11B-Vision-Instruct` model
+- **Cleaning Labels:** With the labels based on the notebook above, we will then clean the dataset and prepare it for RAG
+- **Building Vector DB and RAG Pipeline:** With the final clean dataset, we can use descriptions and 11B model to generate recommendations
+
+## Requirements:
+
+Before we start:
+
+1. Please grab your HF CLI Token from [here](https://huggingface.co/settings/tokens)
+2. git clone [this dataset](https://huggingface.co/datasets/Sanyam/MM-Demo) inside the Multi-Modal-RAG folder: `git clone https://huggingface.co/datasets/Sanyam/MM-Demo`
+3. Launch jupyter notebook inside this folder
+4. We will also run two scripts after the notebooks
+5. Make sure you grab a together.ai token [here](https://www.together.ai)
+
+## Detailed Outline for running:
+
+Order of running files, the notebook establish the method of approaching the problem. Once we establish it, we use the scripts to run the method end to end.
+
+- Notebook 1: `Part_1_Data_Preperation.ipynb`
+- Script: `label_script.py`
+- Notebook 2: `Part_2_Cleaning_Data_and_DB.ipynb`
+- Notebook 3: `Part_3_RAG_Setup_and_Validation.ipynb`
+- Script: `final_demo.py`
+
+Here's the detailed outline:
+
+### Step 1: Data Prep and Synthetic Labeling:
+
+[Notebook for Step 1](./notebooks/Part_1_Data_Preperation.ipynb) and [Script for Step 1](./scripts/label_script.py)
+
+To run the script (remember to set n):
+```
+python scripts/label_script.py --hf_token "your_huggingface_token_here" \
+    --input_path "../MM-Demo/images_compressed" \
+    --output_path "../MM-Demo/output/" \
+    --num_gpus N
+```
+
+The dataset consists of 5000 images with some meta-data.
+
+The first half is preparing the dataset for labeling:
+- Clean/Remove corrupt images
+- EDA to understand existing distribution
+- Merging up categories of clothes to reduce complexity 
+- Balancing dataset by randomly sampling images
+
+Second Half consists of Labeling the dataset. We are bound by an interesting constraint here, 11B model can only caption one image at a time:
+- We load a few images and test captioning
+- We run this pipeline on random images and iterate on the prompt till we feel the model is giving good outputs
+- Finally, we can create a script to label all 5000 images on multi-GPU
+
+After running the script on the entire dataset, we have more data cleaning to perform.
+
+### Step 2: Cleaning up Synthetic Labels and preparing the dataset:
+
+[Notebook for Step 2](./notebooks/Part_2_Cleaning_Data_and_DB.ipynb)
+
+Even after our lengthy (apart from other things) prompt, the model still hallucinates categories and label-we need to address this
+
+- Re-balance the dataset by mapping correct categories
+- Fix Descriptions so that we can create a CSV
+
+Now, we are ready to try our vector db pipeline:
+
+### Step 3: Notebook 3: MM-RAG using lance-db to validate idea
+
+[Notebook for Step 3](./notebooks/Part_3_RAG_Setup_and_Validation.ipynb) and [Final Demo Script](./scripts/label_script.py)
+
+
+With the cleaned descriptions and dataset, we can now store these in a vector-db
+
+You will note that we are not using the categorization from our model-this is by design to show how RAG can simplify a lot of things. 
+
+- We create embeddings using the text description of our clothes
+- Use 11-B model to describe the uploaded image
+- Try to find similar or complimentary images based on the upload
+
+We try the approach with different retrieval methods.
+
+Finally, we can bring this all together in a Gradio App. 
+
+For running the script:
+```
+python scripts/final_demo.py \
+    --images_folder "../MM-Demo/compressed_images" \
+    --csv_path "../MM-Demo/final_balanced_sample_dataset.csv" \
+    --table_path "~/.lancedb" \
+    --api_key "your_together_api_key" \
+    --default_model "BAAI/bge-large-en-v1.5" \
+    --use_existing_table 
+```
+
+Task: We can further improve the description prompt. You will notice sometimes the description starts with the title of the cloth which causes in retrieval of "similar" clothes instead of "complementary" items
+
+- Upload an image
+- 11B model describes the image
+- We retrieve complementary clothes to wear based on the description
+- You can keep the loop going by chatting with the model

+## Resources used: 
+
+Credit and Thanks to List of models and resources used in the showcase:
+
+Firstly, thanks to the author here for providing this dataset on which we base our exercise []()

+- [Llama-3.2-11B-Vision-Instruct Model](https://www.llama.com/docs/how-to-guides/vision-capabilities/)
+- [Lance-db for vector database](https://lancedb.com)
+- [This Kaggle dataset]()
+- [HF Dataset](https://huggingface.co/datasets/Sanyam/MM-Demo) Since output of the model can be non-deterministic every time we run, we will use the uploaded dataset to give a universal experience
