# Resnet50 inference with MIGraphX and Onnxruntime

## Description

This example demonstrates how to perform an MIGraphX Python API inference through onnxruntime. The model used here is from Torchvision's pretrained resnet50 model

## Content

- [**Running this Example**](#Running-this-Example)
- [Example output](#example-Output)

## Basic Setup
Before running inference we must first install MIGraphX via the Docker method as it also downloads onnxruntime into the dockerfile created. 

Starting from project root:
```
$ cd AMDMIGraphX
$ docker build -t migraphx .
$ docker --device='/dev/kfd' --device='/dev/dri' <your docker settings and mounts> --group-add video -it migraphx
```

The dockerfile will install the latest supported version of ROCm with all the depandacnies needed for MIGraphX

Once the docker file has been installed and you're inside the folder run

```
$ rbuild develop -d deps -B build
$ cd build 
$ make -j$(nproc) package && dpkg -i *.deb
```

to verify migraphx has been installed correclty in the docker run dpkg --list or dpkg -l

```
$ dpkg -l | grep migraphx 
$ ii  migraphx                      2.7.0                             amd64        AMD's graph optimizer
$ ii  migraphx-dev                  2.7.0                             amd64        AMD's graph optimizer
```

## Running this Example

This directory contains everything needed to perform an inference once MIGraphX has been installed in the docker container
Once you've build and installed MIGraphX as a deb package, go to the examples folder, run the pre-req script to build and install
onnxruntime and then install the approrpaite version of pytorch from project root.

```
$ 
$ cd examples/onnxruntime/resnet50
$ ./prereq_steps.sh
$ pip list | grep onnxruntime
$ python resnet50.py
```

## Example Output:

We changes the target image to what's found in the example folder which contains three inclass images and one out of class image.

For guitars we show three different variants of the same item in a class with different backgrounds as well as background shapes
