🚀 Production Scientific Deployment Strategy

📋 Deployment Approach

🎯 Strategy: Full scientific deployment only - no minimal fallback
🔬 Complete Stack: py21cmfast, tools21cm, bagpipes, jwst_pipeline, advanced astronomical packages
⚡ Single Configuration: Production-ready with all capabilities enabled

🚀 Production Deployment (Current Active)

Step 1: Replace Requirements File

# Backup current minimal version
cp requirements.txt requirements-minimal-backup.txt

# Use full scientific requirements
cp requirements-full.txt requirements.txt

Step 2: Replace System Packages

# Backup current minimal packages
cp packages.txt packages-minimal-backup.txt

# Use full system packages
cp packages-full.txt packages.txt

Step 3: Commit and Deploy

git add requirements.txt packages.txt
git commit -m "🔬 Enable full scientific packages: py21cmfast, bagpipes, jwst, tools21cm"
git push

⏱️ Expected Deployment Time

  • Minimal Version: 2-3 minutes ✅ (Current)
  • Full Version: 10-15 minutes ⏳ (Target)

Why longer? Heavy packages like jwst (500MB+) and py21cmfast need compilation.

🧪 Package-by-Package Testing (Conservative)

If full deployment fails, try adding packages gradually:

Phase 1: Add Corner Plots

# Add to requirements.txt
corner==2.2.1

Phase 2: Add SED Fitting

# Add to requirements.txt
bagpipes>=1.0.0
cython>=0.29.0

Phase 3: Add 21cm Cosmology

# Add to packages.txt
libfftw3-dev
libgsl-dev
build-essential

# Add to requirements.txt
py21cmfast==3.4.0
tools21cm>=2.0.0

Phase 4: Add JWST Pipeline

# Add to packages.txt
libcfitsio-dev

# Add to requirements.txt
jwst>=1.12.0

🛠️ System Requirements Breakdown

Package System Dependencies Purpose
py21cmfast 3.4.0 libfftw3-dev, libgsl-dev, build-essential Stable 21cm simulations
tools21cm Same as py21cmfast 21cm analysis utilities
bagpipes build-essential, gfortran SED fitting
jwst libcfitsio-dev JWST pipeline
corner (minimal dependencies) Corner plots

🚨 Fallback Plan

If full deployment fails:

  1. Revert to minimal:

    cp requirements-minimal-backup.txt requirements.txt
cp packages-minimal-backup.txt packages.txt
git add . && git commit -m "Revert to minimal for stability"
git push

  2. Use staged approach: Deploy packages one by one using Phase 1-4 above

📊 Feature Status After Full Deployment

Module Minimal Version Full Version
Cosmic Evolution Mock/Demo data Full py21cmfast simulations
Cluster Analyzer Basic analysis Advanced environmental modeling
JWST Pipeline Fallback mode Real JWST data processing
SED Fitting Simple models Full Bagpipes fitting
AI Insights ✅ Available ✅ Enhanced with real data

🎯 Recommendation

Try the Quick Deployment first! Streamlit Cloud has improved significantly and can often handle the full scientific stack. The app is designed with graceful fallbacks, so even if some packages fail, core functionality remains available.
