运行记录

1.建立Mindspore运行环境

1。Mindspore的环境安装指南，按照提示进行https://www.mindspore.cn/install
2.下载Mindspore的yolov5，并下载模型和代码https://www.hiascend.com/zh/software/modelzoo/detail/C/9af06eedaa1b9577d6221a939a31747d

下载这两个文件

3。安装库，cd到模型脚本目录下，运行pip install -r requirements.txt

2.下载运行数据集MSCOCO

什么是COCO数据集？

COCO数据集是一个可用于图像检测（image detection），语义分割（semantic segmentation）和图像标题生成（image captioning）的大规模数据集。它有超过330K张图像（其中220K张是有标注的图像），包含150万个目标，80个目标类别（object categories：行人、汽车、大象等），91种材料类别（stuff categoris：草、墙、天空等），每张图像包含五句图像的语句描述，且有250,000个带关键点标注的行人。
具体的COCO数据集介绍 https://blog.csdn.net/qq_44554428/article/details/122597358

COCO数据集的下载

下载网址：官网下载链接
下载最小的val2017和annotions，放到目录下的datasets文件下

3.根据readme文件提示，运行export.py文件，导出mindir模型文件。

cd scripts
python export.py --ckpt_file [CKPT_PATH] --file_format [EXPORT_FORMAT]
#其中ckpt为ckpt模型文件地址，`EXPORT_FORMAT` 必须在 ["AIR", "MINDIR"]中选择。`BATCH_SIZE` 目前仅支持batch_size为1的推理（不用设置）。

运行后会再主目录下得到yolov5.mindir的模型文件。

4. 在执行推理前，mindir文件必须通过export.py脚本导出。以下展示了使用mindir模型执行推理的示例。

运行指令：bash run_infer_310.sh [MINDIR_PATH] [DATA_PATH] [ANN_FILE] [DVPP] [DEVICE_ID]
阅读readme与sh文件提示，其中 mindir_path 为模型地址；DATApath为MS COCO val2017的images地址；ANN_FILE为标注地址；DVPP为推理设备，设置CPU，DEVICE_ID默认为0，无需设置。
如：

在cmd命令下运行export。py文件，后面加上参数

python export.py --ckpt_file D:\yanyi\project_process\ocr\code\Yolov5_for_MindSpore_1.1_code\weights\yolov5.ckpt --file_format MINDIR

5.运行推理

在执行推理前，mindir文件必须通过export.py脚本导出。以下展示了使用mindir模型执行推理的示例。

bash run_infer_310.sh [MINDIR_PATH] [DATA_PATH] [ANN_FILE] [DVPP] [DEVICE_ID]

在cmd下运行。sh文件，后面加参数

cd scripts 
run_infer_310.sh D:\yanyi\project_process\ocr\code\Yolov5_for_MindSpore_1.1_code\yolov5.mindir D:\yanyi\project_process\ocr\code\Yolov5_for_MindSpore_1.1_code\dataset\val2017 D:\yanyi\project_process\ocr\code\Yolov5_for_MindSpore_1.1_code\dataset\annotations\panoptic_val2017.json CPU

运行run_infer_310.sh 心得

不熟悉shell语言的可以加echo语句输出，查看运行到哪。

运行后会进入编译阶段，这里还没有结果

----------------------------------------目前只有这些-----------------------------------------------------

6运行eval文件

下载MS coco数据集val2017和instances_val2017.json，按照如下排列：

instances_val2017.json放入annotations文件中，val2017放到yolov5目录下，其他不需要设置。
运行命令：

python eval.py --data_dir=./dataset/yolov5/ --pretrained=./weights/yolov5.ckpt --testing_shape=640

运行成功后会出现

2022.7.1

尝试在win系统下运行，太难了最终还是没起来，分享一下可借鉴的推理代码
