## 🤗 Introduction
**What it is.** Yet another implementation of Ultralytics's [YOLOv5](https://github.com/ultralytics/yolov5). yolort aims to make the training and inference of the object detection task integrate more seamlessly together. yolort now adopts the same model structure as the official YOLOv5. The significant difference is that we adopt the dynamic shape mechanism, and within this, we can embed both pre-processing (letterbox) and post-processing (nms) into the model graph, which simplifies the deployment strategy. In this sense, yolort makes it possible to deploy the object detection more easily and friendly on `LibTorch`, `ONNX Runtime`, `TVM`, `TensorRT` and so on.
**About the code.** Follow the design principle of [detr](https://github.com/facebookresearch/detr):
> object detection should not be more difficult than classification, and should not require complex libraries for training and inference.
`yolort` is very simple to implement and experiment with. Do you like the implementation of torchvision's faster-rcnn, retinanet or detr? Do you like yolov5? You'll love `yolort`!

## 🛠️ Usage
There are no extra compiled components in `yolort` and package dependencies are minimal, so the code is very simple to use.
### Installation and Inference Examples
- Above all, follow the [official instructions](https://pytorch.org/get-started/locally/) to install PyTorch 1.8.0+ and torchvision 0.9.0+
- Installation via pip
Simple installation from [PyPI](https://pypi.org/project/yolort/)
```shell
pip install -U yolort
```
Or from Source
```shell
# clone yolort repository locally
git clone https://github.com/zhiqwang/yolort.git
cd yolort
# install in editable mode
pip install -e .
```
- Install pycocotools (for evaluation on COCO):
```shell
pip install -U 'git+https://github.com/ppwwyyxx/cocoapi.git#subdirectory=PythonAPI'
```
- To read a source of image(s) and detect its objects 🔥
```python
from yolort.models import yolov5s
# Load model
model = yolov5s(pretrained=True, score_thresh=0.45)
model.eval()
# Perform inference on an image file
predictions = model.predict("bus.jpg")
# Perform inference on a list of image files
predictions = model.predict(["bus.jpg", "zidane.jpg"])
```
### Loading via `torch.hub`
The models are also available via torch hub, to load `yolov5s` with pretrained weights simply do:
```python
model = torch.hub.load("zhiqwang/yolort:main", "yolov5s", pretrained=True)
```
### Loading checkpoint from official yolov5
The following is the interface for loading the checkpoint weights trained with `ultralytics/yolov5`. Please see our documents on what we [share](https://zhiqwang.com/yolort/notebooks/how-to-align-with-ultralytics-yolov5.html) and how we [differ](https://zhiqwang.com/yolort/notebooks/comparison-between-yolort-vs-yolov5.html) from yolov5 for more details.
```python
from yolort.models import YOLOv5
# Download checkpoint from https://github.com/ultralytics/yolov5/releases/download/v6.0/yolov5s.pt
ckpt_path_from_ultralytics = "yolov5s.pt"
model = YOLOv5.load_from_yolov5(ckpt_path_from_ultralytics, score_thresh=0.25)
model.eval()
img_path = "test/assets/bus.jpg"
predictions = model.predict(img_path)
```
## 🚀 Deployment
### Inference on LibTorch backend
We provide a [tutorial](https://zhiqwang.com/yolort/notebooks/inference-pytorch-export-libtorch.html) to demonstrate how the model is converted into `torchscript`. And we provide a [C++ example](deployment/libtorch) of how to do inference with the serialized `torchscript` model.
### Inference on ONNX Runtime backend
We provide a pipeline for deploying yolort with ONNX Runtime.
```python
from yolort.runtime import PredictorORT
# Load the serialized ONNX model
engine_path = "yolov5n6.onnx"
y_runtime = PredictorORT(engine_path, device="cpu")
# Perform inference on an image file
predictions = y_runtime.predict("bus.jpg")
```
Please check out this [tutorial](https://zhiqwang.com/yolort/notebooks/export-onnx-inference-onnxruntime.html) to use yolort's ONNX model conversion and ONNX Runtime inferencing. And you can use the [example](deployment/onnxruntime) for ONNX Runtime C++ interface.
### Inference on TensorRT backend
The pipeline for TensorRT deployment is also very easy to use.
```python
import torch
from yolort.runtime import PredictorTRT
# Load the serialized TensorRT engine
engine_path = "yolov5n6.engine"
device = torch.device("cuda")
y_runtime = PredictorTRT(engine_path, device=device)
# Perform inference on an image file
predictions = y_runtime.predict("bus.jpg")
```
Besides, we provide a [tutorial](https://zhiqwang.com/yolort/notebooks/onnx-graphsurgeon-inference-tensorrt.html) detailing yolort's model conversion to TensorRT and the use of the Python interface. Please check this [example](deployment/tensorrt) if you want to use the C++ interface.
## 🎨 Model Graph Visualization
Now, `yolort` can draw the model graph directly, checkout our [tutorial](https://zhiqwang.com/yolort/notebooks/model-graph-visualization.html) to see how to use and visualize the model graph.
