MIMO HuggingFace Spaces - Fix Summary

Issues Fixed ✅

1. "Load Model" Button Not Working

Problem: After clicking "Setup Models" successfully, clicking "Load Model" showed "⚠️ Models not found"

Root Cause:

• _check_existing_models() was checking for simple directory paths like ./models/stable-diffusion-v1-5
• Actual HuggingFace cache uses complex structure: ./models/stable-diffusion-v1-5/models--runwayml--stable-diffusion-v1-5/snapshots/[hash]/

Solution:

• Updated _check_existing_models() to detect HuggingFace cache patterns
• Looks for models--org--name directories using rglob() pattern matching
• Sets _model_cache_valid = True after successful download
• Re-checks cache validity when "Load Model" is clicked

2. UI Text Visibility (White on White)

Problem: All text appeared white on white background, making it unreadable

Solution: Added !important flag to all CSS color declarations to override Gradio's defaults

• Headers: color: #2c3e50 !important
• Body text: color: #495057 !important
• Links: color: #3498db !important

3. Model Persistence

Problem: Models seemed to disappear after page refresh

Solution:

• Models actually persist in HuggingFace cache
• Added "⚡ Load Model" button for quick reactivation (30-60 sec vs 10+ min)
• Status message confirms: "✅ Model files found in cache - models persist across restarts!"

How It Works Now ✅

First Time Setup:

1. Click "🔧 Setup Models" (downloads ~8GB, takes 5-10 min)
2. Models automatically load after download
3. Status: "🎉 MIMO is ready! Models loaded successfully..."

After Page Refresh:

1. On page load, system checks for cached models
2. If found, shows: "✅ Found X model components in cache"
3. Click "⚡ Load Model" to activate (30-60 seconds)
4. Status: "✅ Model loaded successfully! Ready to generate videos..."

Model States:

• Not Downloaded: Need to click "Setup Models"
• Downloaded but Not Loaded: Click "Load Model"
• Already Loaded: Shows "✅ Model already loaded and ready!"

Testing Checklist

1. Fresh Page Load:

   • Check console for "✅ Found X model components in cache"
   • UI text is visible (dark text on light background)

2. First Time Setup (if models not downloaded):

   • Click "🔧 Setup Models"
   • Wait for download (~5-10 min)
   • Check status: "🎉 MIMO is ready! Models loaded successfully..."
   • Models should be ready to use immediately

3. After Page Refresh (models already downloaded):

   • Page loads, shows cache found message
   • Click "⚡ Load Model"
   • Wait 30-60 seconds
   • Check status: "✅ Model loaded successfully!"

4. Template Operations:

   • Click "🔄 Refresh Templates"
   • Dropdown shows available templates
   • Select template from dropdown

5. Video Generation:

   • Upload character image
   • Select template
   • Choose mode (animate/edit)
   • Click "🎬 Generate Video"
   • Wait 2-5 minutes
   • Video appears in output

Known Behavior

✅ Expected:

• Models persist in cache across page refreshes
• Need to click "Load Model" after refresh (one-time per session)
• Template upload takes 10-20 minutes for all 8 remaining
• First video generation may take longer (model warmup)

⚠️ Limitations:

• ZeroGPU has quota limits for unlogged users
• Large templates increase storage usage
• Generation time varies with template length
