1. 简介

本文档记录 Irodori-TTS-500M-v2 在华为昇腾 NPU 环境下的适配验证、推理部署与评测结果整理。

Irodori-TTS-500M-v2 的当前适配任务类型为：语音合成 / 文本转语音。仓库围绕 赛道一模型适配 交付要求，提供 NPU 推理脚本、精度评测、性能评测、运行日志、结果文件和文本化自验证证据。

2. 适配内容

2.1 NPU 推理适配

仓库提供 inference.py 作为统一推理入口，运行时通过 --device npu 或脚本默认设备在昇腾 NPU 上执行推理。推理代码保留 model.eval()、无梯度推理、输入输出摘要、耗时统计和日志保存逻辑，便于复现与核验。

2.2 精度与性能评测

仓库保留精度评测与性能评测材料。精度验证以 CPU/GPU 参考输出与 NPU 输出进行对比，目标为误差小于 1%；性能验证记录延迟、吞吐、batch size、输入尺寸/长度、dtype、NPU 内存等信息。所有结果以 logs/ 与 results/ 中的真实运行文件为准。

2.3 证据文本化与提交整理

自验证截图中的关键内容已转写为 README 文本证据，避免仅依赖图片展示。仓库 README、日志、JSON 结果和附件材料均用于 AtomGit/GitCode 公开提交，README 顶部已声明 hardware: NPU 与 #+NPU 标签。

3. 环境要求

组件	版本 / 说明
操作系统	Linux
CANN	8.5.1
PyTorch	2.9.0+cpu
torch_npu	2.9.0.post1
transformers	4.57.6
accelerate	N/A
依赖安装	`pip install -r requirements.txt`

NPU：Ascend NPU（具体型号以 results/env_info.json 或 logs/env_check.log 为准）
Python：3.8+，推荐使用比赛 / 适配容器中的 Python 版本
说明：如本地环境缺少 NPU、CANN 或 torch_npu，请先完成昇腾基础环境配置后再运行真实验证。
