A newer version of the Streamlit SDK is available: 1.52.2

Upgrade

✅ HuggingFace Spaces Implementation - Complete!

What Was Done

Your SAP Chatbot is now fully configured for HuggingFace Spaces multi-user deployment! 🎉

Code Changes Made:

1. tools/agent.py - Enhanced HuggingFace Inference API

✅ Improved query_huggingface() method with:
- Model mapping to actual HF model IDs
- Better error handling (rate limits, timeouts, auth errors)
- Proper response parsing from HF Inference API
- Cloud-friendly timeout handling
✅ Added huggingface_hub import for data downloads

2. tools/embeddings.py - Added HF Hub Loading

✅ New method: load_from_hf_hub(repo_id) to download index/metadata
✅ Auto-detects when running in HF Spaces
✅ Falls back to local files if HF Hub not available
✅ Supports both local and cloud data sources

3. config.py - Environment Auto-Detection

✅ Auto-detects HF Spaces environment (SPACE_ID env var)
✅ Auto-detects Streamlit Cloud
✅ Sets appropriate LLM defaults:
- HF Spaces → HuggingFace Inference API
- Local → Ollama
✅ Updated HF model options with proper IDs

4. app.py - Enhanced UI for Cloud

✅ RAG init tries HF Hub first, fallback to local
✅ Shows environment (Local vs 🤗 HF Spaces)
✅ Added "Deploy to HF Spaces" help section
✅ Improved cloud error messages

New Files Created:

File	Purpose
requirements-spaces.txt	Cloud-optimized dependencies
.streamlit/config.toml	Streamlit cloud config
DEPLOYMENT_HF_SPACES.md	Detailed deployment guide (500+ lines)
SETUP_SPACES.md	Quick setup steps (400+ lines)

Deploy in 30 Minutes

Phase 1: Prepare Data (5 min)

Get your HuggingFace token:

# Visit https://huggingface.co/settings/tokens
# Create token with "read" access
# Copy the token

Create dataset repo and upload files:

pip install huggingface-hub
huggingface-cli login  # Paste your token

# Create repo on https://huggingface.co/datasets
# Then upload your data files:

huggingface-cli upload YOUR-USERNAME/sap-chatbot-data \
  data/rag_index.faiss data/rag_index.faiss

huggingface-cli upload YOUR-USERNAME/sap-chatbot-data \
  data/rag_metadata.pkl data/rag_metadata.pkl

huggingface-cli upload YOUR-USERNAME/sap-chatbot-data \
  data/sap_dataset.json data/sap_dataset.json

Phase 2: Push to GitHub (5 min)

cd /Users/akshay/sap-chatboot

git init
git add .
git commit -m "SAP Chatbot for HF Spaces"

# Create repo on github.com, then:
git remote add origin https://github.com/YOUR-USERNAME/sap-chatbot.git
git branch -M main
git push -u origin main

Phase 3: Create HF Space (5 min)

Visit https://huggingface.co/spaces
Click "Create new Space"
Fill in:
- Name: sap-chatbot
- SDK: Streamlit
- Visibility: Public or Private
Click "Create Space"
Connect your GitHub repo (Settings → Linked Repository)

Phase 4: Add Secrets (5 min)

In Space Settings → "Secrets":

HF_API_TOKEN = hf_xR9q... (your token from Phase 1)
HF_DATASET_REPO = your-username/sap-chatbot-data
LLM_PROVIDER = huggingface
LLM_MODEL = mistral

Phase 5: Deploy & Test (5 min)

Space auto-builds (~5 min on first run)
Click "Open in iframe"
Wait 10-15 seconds for initialization
Test: "How do I monitor SAP background jobs?"
See answer with sources!
