MXNet-HRT

MXNet-HRT is a project that is maintained by OPEN AI LAB, it uses Arm Compute Library (NEON+GPU) to speed up MXNet and provide utilities to debug, profile and tune application performance.

The release version is 0.3.1, is based on Rockchip RK3399 Platform, target OS is Ubuntu 16.04. Can download the source code from OAID/MXNet-HRT

Arm Compute Library Compatibility Issues :

There are some compatibility issues between ACL and MXNet Layers, we bypass it to MXNet's original layer class as the workaround solution for the below issues

• Normalization in-channel issue
• Tanh issue
• Softmax supporting multi-dimension issue
• Group issue

Performance need be fine turned in the future
