"""
Ultralytics neural network modules.

This module provides access to various neural network components used in Ultralytics models, including convolution
blocks, attention mechanisms, transformer components, and detection/segmentation heads.

Examples:
    Visualize a module with Netron
    >>> from ultralytics.nn.modules import Conv
    >>> import torch
    >>> import subprocess
    >>> x = torch.ones(1, 128, 40, 40)
    >>> m = Conv(128, 128)
    >>> f = f"{m._get_name()}.onnx"
    >>> torch.onnx.export(m, x, f)
    >>> subprocess.run(f"onnxslim {f} {f} && open {f}", shell=True, check=True)  # pip install onnxslim
