# MNASNet_b1
Quantized MNASNet_b1 model that could be supported by [AMD Ryzen AI](https://ryzenai.docs.amd.com/en/latest/).


## Model description
MNASNet was first introduced in the paper [MnasNet: Platform-Aware Neural Architecture Search for Mobile](https://arxiv.org/abs/1807.11626).

The model implementation is from [timm](https://huggingface.co./timm/mnasnet_100.rmsp_in1k).


## How to use

### Installation

Follow [Ryzen AI Installation](https://ryzenai.docs.amd.com/en/latest/inst.html) to prepare the environment for Ryzen AI.
Run the following script to install pre-requisites for this model.

```bash
pip install -r requirements.txt 
```

### Data Preparation

Follow [ImageNet](https://huggingface.co./datasets/imagenet-1k) to prepare dataset.

### Model Evaluation

```python
python eval_onnx.py --onnx_model mnasnet_b1_int.onnx --ipu --provider_config Path\To\vaip_config.json --data_dir /Path/To/Your/Dataset
```
