BrokenPipeError: [Errno32] Broken pipe

3. 根因分析

报错信息为读写失败，定位方向为：查看代码中，是否有往磁盘读写文件的操作
原因：

context.set_context(mode=context.GRAPH_MODE, device_target=opt.device_target, enable_compile_cache=True, compile_cache_path="./cache", max_call_depth=4096)

代码中开启了编译缓存，但写入的路径，本地没有。

4. 解决方案

修改context为

context.set_context(mode=context.GRAPH_MODE, device_target=opt.device_target, max_call_depth=4096)

删除enable_compile_cache=True, compile_cache_path="./cache"
