pip install transformers torch_npu -i https://huaweimirror.com.cn/simple运行推理脚本进行翻译:
cd /data/ysws/agentsp/5-18/opus-mt-tr-en-ascend/
python3 inference.py运行精度对比测试,验证 NPU 计算结果与 CPU 一致性:
cd /data/ysws/agentsp/5-18/opus-mt-tr-en-ascend/
python3 inference.py precision_test| 指标 | 实测值 | 阈值 | 状态 |
|---|---|---|---|
| 翻译一致性 | 100% | 100% | PASS |
| 输出匹配 | True | True | PASS |
| 操作 | 耗时 |
|---|---|
| CPU 推理时间 | 1.950s |
| NPU 推理时间 | 0.126s |
| 加速比 | 15.47x |
| 输入 (土耳其语) | 输出 (英语) |
|---|---|
| "Merhaba, nasılsın bugün?" | "Hi, how are you today?" |
| "Seni görmek çok güzel." | "It's great to see you." |
| "Hava bugün güzel." | "The weather is nice today." |
结果: CPU 和 NPU 输出的翻译结果完全一致

}A: 检查 NPU 驱动是否正确安装,确保 CANN 环境变量已 source。
A: 使用批处理可以显著提高吞吐量。另外,首次推理会有编译开销,后续推理会更快。
A: 本模型专门用于土耳其语到英语的翻译。如需其他语言对,请访问 Helsinki-NLP 模型库。
