🐛 Bug

To Reproduce

Steps to reproduce the behavior (always include the command you ran):

1. 启动 Triton Inference Server 服务，命令示例：tritonserver --model-repository=/workspace/models --http-port=8000 --grpc-port=8001 --metrics-port=8002
2. 服务初始化过程中，Triton 加载 feature_extractor（GPU 部署）、scoring（CPU 部署）及 punc_ct-transformer_zh-cn-common-vocab272727-onnx（标点模型）时，出现异常日志，标点模型加载失败。

Code sample

（模型加载核心代码片段，来自 model.py 关键逻辑）

模型加载相关代码（示例，与日志中 model.py:205/208/211/236 对应）

def load_punctuation_model(model_path): print(f"Attempting to load punctuation model from specified path: {model_path}") if not os.path.exists(model_path): raise FileNotFoundError(f"Model directory not exists: {model_path}") print(f"Model directory exists: {model_path}")

config_path = os.path.join(model_path, "config.yaml")
if not os.path.exists(config_path):
    raise FileNotFoundError(f"Model config file not exists: {config_path}")
print(f"Model config file exists: {config_path}")

try:
    # 调用 funasr_onnx 加载模型的逻辑
    from funasr_onnx import Punctuation
    punc_model = Punctuation(model_dir=model_path)  # 此处抛出非标准异常
    return punc_model

Expected behavior

标点模型（punc_ct-transformer_zh-cn-common-vocab272727-onnx）应正常加载，Triton 服务初始化完成后，标点恢复功能可正常启用，无 Punctuation restoration will be disabled 警告。

Environment

• OS (e.g., Linux): Ubuntu 20.04 LTS
• FunASR Version (e.g., 1.0.0):
• ModelScope Version (e.g., 1.11.0):
• PyTorch Version (e.g., 2.0.0):
• How you installed funasr (pip, source): pip install funasr_onnx
• Python version: 3.10
• GPU (e.g., V100M32) A10
• CUDA/cuDNN version (e.g., cuda11.7):
• Docker version (e.g., funasr-runtime-sdk-cpu-0.4.1)
• Any other relevant information:

Additional context

1. 已确认标点模型目录（/workspace/models/punc_ct-transformer_zh-cn-common-vocab272727-onnx）及配置文件（config.yaml）存在，且模型文件（.onnx）未损坏。
2. 异常提示 “funasr_onnx 抛出非标准异常（未继承 BaseException）” 为库已知问题，尝试过重新安装 funasr_onnx 但未解决，需确认是否有版本兼容或补丁方案。
3. 目前仅标点恢复功能受影响，feature_extractor 和 scoring 模型可正常初始化。
