## Model Description
|
| 21 |
-
|
| 22 |
-
The model is a `ComplexUNet` architecture, a variant of the standard U-Net. It features:
|
| 23 |
-
- **Deeper Architecture**: 4 downsampling and 4 upsampling stages.
|
| 24 |
-
- **Residual Blocks**: Each stage uses residual blocks instead of simple convolutional layers.
|
| 25 |
-
- **Increased Width**: The model was trained with `base_channels=96`.
|
| 26 |
-
- **Total Parameters**: 73,148,259
|
| 27 |
-
|
| 28 |
-
## How to Use
|
| 29 |
-
|
| 30 |
-
First, install the required libraries:
|
| 31 |
-
```bash
|
| 32 |
-
pip install torch torchvision numpy Pillow
|
| 33 |
-
```
|
| 34 |
-
|
| 35 |
-
Then, you can load the model and perform inpainting on an image tensor.
