[bug] qwen2.5-3b smooth_quant量化后的模型,图模式zeros op bug #216

Description

@zzhaowendao

复现步骤:
1.量化模型:python -m lmdeploy lite smooth_quant --device npu qwen2.5-3b
2.执行推理:python -m lmdeploy serve api_server qwen2.5-3b-w8a8 --backend pytorch --device ascend,刚启动起来并无报错。

开始聊天则报错如下:
torch._dynamo.exc.BackendCompilerFailed: backend='atbgraph' raised:
TypeError: AtbOverrides.Zeros() missing 1 required positional argument: 'origin_size'

另外如果是原版模型执行推理,则没有报错:
python -m lmdeploy serve api_server qwen2.5-3b --backend pytorch --device ascend,可以正常聊天。
