precision 是? |
16位的模型,cost是ms |
运行性能与模型无关,主要是 precision 设的是 normal / high / low ? |
有用 benchmark.out 测试过么? |
benchmark.out测试方法有文档么 |
2.7.0 vulkan推理误差变小了,速度问题还没有解决是吗 |
这个模型到后面尺寸较大,被 vulkan image 拆成了很多份 image ,执行效率下降。速度问题由于 厂商加速相关扩展主要在 opencl ,mnn 主要基于 opencl 优化,建议都优先使用 opencl 。mnn vulkan 主要是启动性能上有优势。 |
