train_deim_v2

Train DEIMv2 object detection 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 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": "detection",
}) 

# Add training algorithm
train = wf.add_task(name="train_deim_v2", 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

• model_name (str) - default 'n_coco': Name of the DEIMv2 pre-trained model on COCO. Other model available:

  • s_coco
  • m_coco
  • l_coco
  • x_coco
  • femto_coco
  • pico_coco

• batch_size (int) - default '8': Number of samples processed before the model is updated.

• epochs (int) - default '50': 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 '0.0001': Amount of weight decay, regularization method.

• workers (int) - default '0': Number of worker threads for data loading (per RANK if DDP).

• lr (float) - default '0.0005': Initial learning rate. Adjusting this value is crucial for the optimization process, influencing how rapidly model weights are updated.

• output_folder (str, optional): path to where the model will be saved.

• config_file (str, optional): path to the training config file .yaml. Using a config file allows you to set all the train settings available.

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