考点（AI 标注）模拟/实现
HackerCars is building a self-driving car. Given a training dataset of speed-sign images and labels (0 = 30 km/h, 1 = 70 km/h, 2 = 120 km/h), build a PyTorch model that predicts a label for each test image and writes submissions.csv (path,label).
Schema:
| Field | Type | Description |
|---|---|---|
path | str | image path under test/ |
label | int | 0 = 30 km/h, 1 = 70 km/h, 2 = 120 km/h |
Evaluation metric: accuracy.
