"""Ascend quantization scheme implementations.
|
|
|
|
This module provides all quantization scheme implementations for Ascend NPU.
|
|
Schemes are automatically registered via the @register_scheme decorator.
|
|
|
|
Usage:
|
|
from vllm_ascend.quantization.methods import get_scheme_class
|
|
|
|
# Get a scheme class by quant_type and layer_type
|
|
scheme_cls = get_scheme_class("W8A8_DYNAMIC", "linear")
|
|
scheme = scheme_cls()
