海思ss928|3403模型加载失败,svp_npu_runtime_mem_flush_cache_with_phys_addr [Line]:381 [Info]:Error, flush cac

问题描述

使用以下链接中提供的demo
https://mp.weixin.qq.com/s/MTKcPa0ZHU8EyJkdpM94eQ
在ss928上运行yolov5,yolov8时模型无法加载，报错如下：

软硬件版本

硬件：易佰纳海鸥派4G
系统:易佰纳ubuntu_v1.1.1
SDK:SS928 V100R001C02SPC022（Update）

问题出现的环境背景及自己尝试过哪些方法

模型使用公众号里docker提供的yolov5_original.om，根据公众号的方法或者sdk例程中readme的方法转换的yolov8_original.om模型，上述模型加载时均报相同的错误。
