About
Train YOLOv8 instance segmentation models.
Train YOLOv8 instance segmentation models.
🚀 Use with Ikomia API
1. Install Ikomia API
We strongly recommend using a virtual environment. If you're not sure where to start, we offer a tutorial here.
pip install ikomia
2. Create your workflow
from ikomia.dataprocess.workflow import Workflow# Init your workflowwf = Workflow()# Add dataset loadercoco = wf.add_task(name="dataset_coco")coco.set_parameters({"json_file": "path/to/json/annotation/file","image_folder": "path/to/image/folder","task": "instance_segmentation",})# Add training algorithmtrain = wf.add_task(name="train_yolo_v8_seg", auto_connect=True)# Launch your training on your datawf.run()
☀️ Use with Ikomia Studio
Ikomia Studio offers a friendly UI with the same features as the API.

📝 Set algorithm parameters
-
model_name (str) - default 'yolov8m-seg': Name of the YOLOv8 pre-trained model. Other model available:
- yolov8n-seg
- yolov8s-seg
- yolov8l-seg
- yolov8x-seg
-
batch_size (int) - default '8': Number of samples processed before the model is updated.
-
epochs (int) - default '100': Number of complete passes through the training dataset.
-
dataset_split_ratio (float) – default '0.9': Divide the dataset into train and evaluation sets ]0, 1[.
-
input_size (int) - default '640': Size of the input image.
-
weight_decay (float) - default '0.0005': Amount of weight decay, regularization method.
-
momentum (float) - default '0.937': Optimization technique that accelerates convergence.
-
workers (int) - default '0': Number of worker threads for data loading (per RANK if DDP).
-
optimizer (str) - default '0.937': Optimizer to use, choices=[SGD, Adam, Adamax, AdamW, NAdam, RAdam, RMSProp, auto]
-
lr0 (float) - default '0.01': Initial learning rate (i.e. SGD=1E-2, Adam=1E-3)
-
lr1 (float) - default '0.01': Final learning rate (lr0 * lrf)
-
output_folder (str, optional): path to where the model will be saved.
-
config_file (str, optional): path to the training config file .yaml.
Parameters should be in strings format when added to the dictionary.
