@rahul_s
Did you follow this doc to test ?

Yes Frank. WHy is it saying create graph failed ?

@rahul_s What I have encountered before is that there is no parameter added

$ git clone --recursive https://github.com/khadas/aml_npu_demo_binaries

I had test it last week. It should be right. Did you upgrade you system to least OTA version ?
