Hi, I followed the official document about UDO tutorial to compile the Softmax op for the DSP, but encountered a "cannot load symbol" error while compiling the V68 architecture Softmax op,
- Device: Mi 11 (sdm 888)
- Version: SNPE-1.46.0
- Hexagon DSP SDK version: 3.5.2
- DSP UDO target architecture: V68
Here is the compilation log

After this I try SNPE-1.48, It shows that I need to setup QNN_SDK_ROOT variable, but I can't find this SDK, where should I download QNN SDK?
