💻 Quickstart Inference Code

import torch
import numpy as np
from PIL import Image
from huggingface_hub import hf_hub_download
from model import TreeDetectorModel

# 1. Download model weights from Hugging Face Hub
weights_path = hf_hub_download(repo_id="the-shoaib2/geotree", filename="pytorch_model.bin")

# 2. Instantiate and load model
model = TreeDetectorModel()
model.load_state_dict(torch.load(weights_path, map_location="cpu"))
model.eval()

# 3. Load & preprocess image
img = Image.open("sample_tile.png").convert("RGB").resize((640, 640))
img_tensor = torch.tensor(np.array(img).transpose(2, 0, 1).astype(np.float32) / 255.0).unsqueeze(0)

# 4. Predict
with torch.no_grad():
    output = model(img_tensor).squeeze(0)
    conf = torch.sigmoid(output[0]).item()
    bbox = output[1:].tolist()

print(f"Tree Detected: {conf > 0.3} | Confidence: {conf:.2f} | BBox: {bbox}")
