# ResNet-50: Image Classification
ResNet is a network with a better effect on classification problems in the ImageNet competition.
It introduces the concept of residual learning, protects the integrity of information by adding direct channels, and solves problems such as information loss, gradient disappearance, and gradient explosion. The network is also trained. ResNet has different network layers, commonly used are 18-layer, 34-layer, 50-layer, 101-layer, 152-layer. The meaning of ResNet50 means that there are 50-layers in the network. It is currently more commonly used because it takes into account both speed and accuracy.
The model can be found [here](https://github.com/pytorch/vision/blob/main/torchvision/models/resnet.py)

## Inference
### Step1: convert model
a. Prepare source model in onnx format. The source model can be found [here](https://huggingface.co/aplux/ResNet-50/blob/main/resnet50.onnx).
b. Login [AIMO](https://aidlux.com/en/product/aimo) and convert source model to target format. The model conversion step can follow **AIMO Conversion Step** in [Model Conversion Sheet](#model-conversion).
c. After conversion task done, download target model file.
### Step2: install AidLite SDK
The installation guide of AidLite SDK can be found [here](https://huggingface.co/datasets/aplux/AIToolKit/blob/main/AidLite%20SDK%20Development%20Documents.md#installation).
### Step3: run demo program
