# Cow-axera

This version of **Cow-axera** has been converted to run on the Axera NPU using **w8a16** quantization. It is trained to detect cows in the wild.

## Supported Classes

This model is trained to detect cows with one class:
1. **Cow**

Compatible with Pulsar2 version: 6.0.

## Convert tools links:

For those who are interested in model conversion, you can try to export axmodel through:
