"""
|
|
Loads a UNet diffusion model from a state dictionary, supporting both diffusers and regular formats.
|
|
|
|
Args:
|
|
sd (dict): State dictionary containing model weights and configuration
|
|
model_options (dict, optional): Additional options for model loading. Supports:
|
|
- dtype: Override model data type
|
|
- custom_operations: Custom model operations
|
|
- fp8_optimizations: Enable FP8 optimizations
|
|
|
|
Returns:
|
|
ModelPatcher: A wrapped model instance that handles device management and weight loading.
|
|
Returns None if the model configuration cannot be detected.
|
|
|
|
The function:
|
|
1. Detects and handles different model formats (regular, diffusers, mmdit)
|
|
2. Configures model dtype based on parameters and device capabilities
|
|
3. Handles weight conversion and device placement
|
|
4. Manages model optimization settings
|
|
5. Loads weights and returns a device-managed model instance
