[Ultralytics HUB](https://hub.ultralytics.com) is a new no-code online tool developed
|
|
||||||
by [Ultralytics](https://ultralytics.com), the creators of the popular [YOLOv5](https://github.com/ultralytics/yolov5)
|
|
||||||
object detection and image segmentation models. With Ultralytics HUB, users can easily train and deploy YOLO models
|
|
||||||
without any coding or technical expertise.
|
|
||||||
|
|
||||||
Ultralytics HUB is designed to be user-friendly and intuitive, with a drag-and-drop interface that allows users to
|
|
||||||
easily upload their data and select their model configurations. It also offers a range of pre-trained models and
|
|
||||||
templates to choose from, making it easy for users to get started with training their own models. Once a model is
|
|
||||||
trained, it can be easily deployed and used for real-time object detection and image segmentation tasks. Overall,
|
|
||||||
Ultralytics HUB is an essential tool for anyone looking to use YOLO for their object detection and image segmentation
|
|
||||||
projects.
|
|
||||||

|
||||||
**[Get started now](https://hub.ultralytics.com)** and experience the power and simplicity of Ultralytics HUB for
|
|
||||||
yourself. Sign up for a free account and start building, training, and deploying YOLOv5 and YOLOv8 models today.
|
|
||||||
|
|
||||||
## 1. Upload a Dataset
|
|
||||||
|
|
||||||
Ultralytics HUB datasets are just like YOLOv5 🚀 datasets, they use the same structure and the same label formats to keep
|
|
||||||
everything simple.
|
|
||||||
|
|
||||||
When you upload a dataset to Ultralytics HUB, make sure to **place your dataset YAML inside the dataset root directory**
|
|
||||||
as in the example shown below, and then zip for upload to https://hub.ultralytics.com/. Your **dataset YAML, directory
|
|
||||||
and zip** should all share the same name. For example, if your dataset is called 'coco6' as in our
|
|
||||||
example [ultralytics/hub/coco6.zip](https://github.com/ultralytics/hub/blob/master/coco6.zip), then you should have a
|
|
||||||
coco6.yaml inside your coco6/ directory, which should zip to create coco6.zip for upload:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
zip -r coco6.zip coco6
|
|
||||||
```
|
|
||||||
|
|
||||||
The example [coco6.zip](https://github.com/ultralytics/hub/blob/master/coco6.zip) dataset in this repository can be
|
|
||||||
downloaded and unzipped to see exactly how to structure your custom dataset.

|
|
||||||

The dataset YAML is the same standard YOLOv5 YAML format. See
|
|

|
|
||||||
|
|
||||||
After zipping your dataset, sign in to [Ultralytics HUB](https://bit.ly/ultralytics_hub) and click the Datasets tab.
|
|
||||||
Click 'Upload Dataset' to upload, scan and visualize your new dataset before training new YOLOv5 models on it!

|
|
||||||
|
|
||||||
Connect to the Ultralytics HUB notebook and use your model API key to begin training!

## 3. Deploy to Real World
|
|
||||||
|
|
||||||
Export your model to 13 different formats, including TensorFlow, ONNX, OpenVINO, CoreML, Paddle and many others. Run
|
|
||||||
models directly on your [iOS](https://apps.apple.com/xk/app/ultralytics/id1583935240) or

# YOLO Inference API (UNDER CONSTRUCTION)
|
|
||||||
|
|
||||||
The YOLO Inference API allows you to access the YOLOv8 object detection capabilities via a RESTful API. This enables you to run object detection on images without the need to install and set up the YOLOv8 environment locally.
|
|
||||||
|
|
||||||
## API URL
|
|
||||||
|
|
||||||
The API URL is the address used to access the YOLO Inference API. In this case, the base URL is:
|
|
||||||
|
|
||||||
```
|
|
||||||
https://api.ultralytics.com/inference/v1
|
|
||||||
```
|
|
||||||
|
|
||||||
To access the API with a specific model and your API key, you can include them as query parameters in the API URL. The `model` parameter refers to the `MODEL_ID` you want to use for inference, and the `key` parameter corresponds to your `API_KEY`.
|
|
||||||
|
|
||||||
The complete API URL with the model and API key parameters would be:
|
|
||||||
|
|
||||||
```
|
|
||||||
https://api.ultralytics.com/inference/v1?model=MODEL_ID&key=API_KEY
|
|
||||||
```
|
|
||||||
|
|
||||||
Replace `MODEL_ID` with the ID of the model you want to use and `API_KEY` with your actual API key from [https://hub.ultralytics.com/settings?tab=api+keys](https://hub.ultralytics.com/settings?tab=api+keys).
|
|
||||||
|
|
||||||
## Example Usage in Python
|
|
||||||
|
|
||||||
To access the YOLO Inference API with the specified model and API key using Python, you can use the following code:
|
|
||||||
|
|
||||||
```python
|
|
||||||
import requests
|
|
||||||
|
|
||||||
api_key = "API_KEY"
|
|
||||||
model_id = "MODEL_ID"
|
|
||||||
url = f"https://api.ultralytics.com/inference/v1?model={model_id}&key={api_key}"
|
|
||||||
image_path = "image.jpg"
|
|
||||||
|
|
||||||
with open(image_path, "rb") as image_file:
|
|
||||||
files = {"image": image_file}
|
|
||||||
response = requests.post(url, files=files)
|
|
||||||
|
|
||||||
print(response.text)
|
|
||||||
```
|
|
||||||
|
|
||||||
In this example, replace `API_KEY` with your actual API key, `MODEL_ID` with the desired model ID, and `image.jpg` with the path to the image you want to analyze.
|
|
||||||
|
|
||||||
|
|
||||||
## Example Usage with CLI
|
|
||||||
|
|
||||||
You can use the YOLO Inference API with the command-line interface (CLI) by utilizing the `curl` command. Replace `API_KEY` with your actual API key, `MODEL_ID` with the desired model ID, and `image.jpg` with the path to the image you want to analyze:
|
|
||||||
|
|
||||||
```commandline
|
|
||||||
curl -X POST -F image=@image.jpg "https://api.ultralytics.com/inference/v1?model=MODEL_ID&key=API_KEY"
|
|
||||||
```
|
|
||||||
|
|
||||||
## Passing Arguments
|
|
||||||
|
|
||||||
This command sends a POST request to the YOLO Inference API with the specified `model` and `key` parameters in the URL, along with the image file specified by `@image.jpg`.
|
|
||||||
|
|
||||||
Here's an example of passing the `model`, `key`, and `normalize` arguments via the API URL using the `requests` library in Python:
|
|
||||||
|
|
||||||
```python
|
|
||||||
import requests
|
|
||||||
|
|
||||||
api_key = "API_KEY"
|
|
||||||
model_id = "MODEL_ID"
|
|
||||||
url = "https://api.ultralytics.com/inference/v1"
|
|
||||||
|
|
||||||
# Define your query parameters
|
|
||||||
params = {
|
|
||||||
"key": api_key,
|
|
||||||
"model": model_id,
|
|
||||||
"normalize": "True"
|
|
||||||
}
|
|
||||||
|
|
||||||
image_path = "image.jpg"
|
|
||||||
|
|
||||||
with open(image_path, "rb") as image_file:
|
|
||||||
files = {"image": image_file}
|
|
||||||
response = requests.post(url, files=files, params=params)
|
|
||||||
|
|
||||||
print(response.text)
|
|
||||||
```
|
|
||||||
|
|
||||||
In this example, the `params` dictionary contains the query parameters `key`, `model`, and `normalize`, which tells the API to return all values in normalized image coordinates from 0 to 1. The `normalize` parameter is set to `"True"` as a string since query parameters should be passed as strings. These query parameters are then passed to the `requests.post()` function.
|
|
||||||
|
|
||||||
This will send the query parameters along with the file in the POST request. Make sure to consult the API documentation for the list of available arguments and their expected values.
|
|
||||||
|
|
||||||
## Return JSON format
|
|
||||||
|
|
||||||
The YOLO Inference API returns a JSON list with the detection results. The format of the JSON list will be the same as the one produced locally by the `results[0].tojson()` command.
|
|
||||||
|
|
||||||
The JSON list contains information about the detected objects, their coordinates, classes, and confidence scores.
|
|
||||||
|
|
||||||
### Detect Model Format
|
|
||||||
|
|
||||||
YOLO detection models, such as `yolov8n.pt`, can return JSON responses from local inference, CLI API inference, and Python API inference. All of these methods produce the same JSON response format.
|
|
||||||
|
|
||||||
