train_unet

Train UNet model for semantic segmentation.

🚀 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 workflow
wf = Workflow()    

# Add dataset loader
coco = wf.add_task(name="dataset_coco")

coco.set_parameters({
    "json_file": "path/to/json/annotation/file",
    "image_folder": "path/to/image/folder",
    "task": "semantic_segmentation",
}) 

# Add training algorithm
train = wf.add_task(name="train_unet", auto_connect=True)

# Launch your training on your data
wf.run()

☀️ Use with Ikomia Studio

Ikomia Studio offers a friendly UI with the same features as the API.

• If you haven't started using Ikomia Studio yet, download and install it from this page.

• For additional guidance on getting started with Ikomia Studio, check out this blog post.

📝 Set algorithm parameters

• input_size (int) - default '128': Size of the input image.
• epochs (int) - default '50': Number of complete passes through the training dataset.
• batch_size (int) - default '1': Number of samples processed before the model is updated.
• learning_rate (float) - default '0.001': Step size at which the model's parameters are updated during training.
• val_percent (int) – default '10': Divide the dataset into train and evaluation sets.
• num_channels (int) - default '3': Number of input chanel
• output_folder (str, optional): path to where the model will be saved.

Parameters should be in strings format when added to the dictionary.
