算子融合规则配置功能（optimization_switch）
功能简介
算子编译时，可根据实际业务需要灵活地配置算子融合，以降低网络推理时间、提高整网性能。
本功能是算子融合规则的控制开关，与算子融合规则配置功能（fusion_switch_file）类似，差异如下：
config.fusion_config.fusion_switch_file仅能关闭图融合和UB（Unified Buffer）融合的规则，并且需要单独配置Json文件；而本功能适用于所有融合规则的指定，不需要再单独设置Json文件。如果两个功能都配置，且配置了同一个融合规则，则以本功能配置为准。
使用约束
本功能仅适用于GE图模式场景。
使用方法
该功能通过torchair.get_npu_backend中compiler_config配置，示例如下，仅供参考不支持直接拷贝运行，参数说明参见下表。
import torch_npu, torchair
config = torchair.CompilerConfig()
# 算子融合规则配置开关
config.ge_config.optimization_switch = "Passname1:on;Passname2:off"
npu_backend = torchair.get_npu_backend(compiler_config=config)
opt_model = torch.compile(model, backend=npu_backend)
表 1 参数说明
| 参数名 | 说明 |
|---|---|
| optimization_switch | 算子编译时，融合规则的控制开关。取值格式为key-value键值对，形如"Passname1:on;Passname2:off"，key为Pass名称，value为on（表示开）或off（表示关），不支持大小写模式匹配，多组配置使用英文分号分隔。可配置的融合规则请参见融合规则列表。 |
融合规则列表
注意如下融合规则关闭后，可能会对功能使用有影响，请谨慎操作。更多融合规则的介绍请参见《CANN 图融合和UB融合规则参考》。
