CRITICAL FIX: Resolved PIL compatibility issue!
Root cause identified:
- Our VAE decode was outputting (B, C, H, W) format
- ComfyUI's save_images expects (B, H, W, C) format
- PIL cannot handle (C, H, W) uint8 data correctly
Solution implemented:
- Convert tensor from (B, C, H, W) to (B, H, W, C) using permute(0, 2, 3, 1)
- Updated validation to check channels in last dimension
- Updated tests to expect new format
Test results:
- (1, 3, 512, 512) format: ❌ PIL Error
- (1, 512, 512, 3) format: ✅ PIL Image created successfully
This should resolve the PIL error:
'Cannot handle this data type: (1, 1, 512), |u1'
