+1. Install requirements.
+
+```bash
+pip install -U segmentation_models_pytorch albumentations
+```
+
+2. Run inference.
+
+```python
+import torch
+import requests
+import numpy as np
+import albumentations as A
+import segmentation_models_pytorch as smp
+
+from PIL import Image
+
+device = "cuda" if torch.cuda.is_available() else "cpu"
+
+# Load pretrained model and preprocessing function
+checkpoint = "smp-hub/upernet-convnext-tiny"
+model = smp.from_pretrained(checkpoint).eval().to(device)
+preprocessing = A.Compose.from_pretrained(checkpoint)
+
+# Load image
+url = "https://huggingface.co/datasets/hf-internal-testing/fixtures_ade20k/resolve/main/ADE_val_00000001.jpg"
+image = Image.open(requests.get(url, stream=True).raw)
+
+# Preprocess image
+np_image = np.array(image)
+normalized_image = preprocessing(image=np_image)["image"]
+input_tensor = torch.as_tensor(normalized_image)
+input_tensor = input_tensor.permute(2, 0, 1).unsqueeze(0)  # HWC -> BCHW
+input_tensor = input_tensor.to(device)
+
+# Perform inference
+with torch.no_grad():
+    output_mask = model(input_tensor)
+
+# Postprocess mask
+mask = mask.argmax(1).cpu().numpy()  # argmax over predicted classes (channels dim)
+```
+
+
+## Model init parameters
+```python
+model_init_params = {
+    "encoder_name": "tu-convnext_tiny.in12k_ft_in1k",
+    "encoder_depth": 5,
