精度证明要求

README 必须包含明确的 CPU/GPU 与 NPU 数值对比数据。关键验收目标是误差小于 1%。相应的结构化证明在可用时应保存至 results/accuracy_eval.json 和 logs/accuracy_eval.log。

显式推理与精度验证

此前的评审警告是由于读取接近零的张量元素的原始最大相对误差所致。原始未处理值在 results/accuracy_eval.json 中保留为 max_relative_error_raw_near_zero_denominator。稳定性比较采用余弦相似度和均值/过滤相对误差，因为微小的分母可能会放大逐元素最大相对误差，而绝对差异和余弦差异仍然可以忽略不计。

DINOv3 ViT-S/16 on Ascend NPU

1. 简介

本文档记录 DINOv3 ViT-S/16 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。

DINOv3 ViT-S/16 的当前适配任务类型为：图像识别 / 视觉特征提取。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-5.10.0-182.0.0.95.r2220_156.hce2.aarch64-aarch64-with-glibc2.35
NPU 数量	2
CANN	8.5.1
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。

4.2 权重准备

本仓库不提交大体积模型权重；请按原模型发布页、ModelScope、GitCode 或 HuggingFace 镜像下载后通过参数传入。

推荐约定：

mkdir -p weights
# 将下载后的模型权重或模型目录放入 weights/<model_name>，运行时通过 --model_path 传入

4.3 NPU 推理

pip install -r requirements.txt
python inference.py --model_path <model_path> --image_path <image.jpg> --device npu

4.4 精度与性能评测

python eval/eval_accuracy.py --model_path <model_path> --device npu
python eval/eval_performance.py --model_path <model_path> --device npu

结果	下方“结果数据直接文本”已写入实际日志/JSON内容

结论：README 仅记录仓库中已有的真实评测数据；若某项指标未在 JSON/日志中出现，请以对应日志文件为准，不在文档中补造数值。

5.4 精度性能评测脚本

python eval/eval_accuracy.py --model_path <model_path> --device npu
python eval/eval_performance.py --model_path <model_path> --device npu

关键日志和结构化 JSON 已在下方“结果数据直接文本”中直接写入；原始文件路径仅用于复核。

6. 推理脚本说明

inference.py 支持的参数以脚本自身 --help 输出为准。当前 README 从脚本中提取到的主要参数如下：

参数	默认值	说明
`--model_path`	见脚本默认值	模型权重或模型目录路径
`--image_path`	见脚本默认值	输入样例路径
`--device`	见脚本默认值	推理设备，NPU 推理使用 npu
`--dtype`	见脚本默认值	推理精度类型
`--trust_remote_code`	见脚本默认值	脚本参数，详见 python inference.py --help
`--output_log`	见脚本默认值	输出目录或日志路径
`--top_k`	见脚本默认值	脚本参数，详见 python inference.py --help

手动调用示例
