vxCreateContext returns 0 on VIM3 board

[dantiana]

File vsi_nn_context.c, line 153, the vxCreateContext() returns 0, why?

c = vxCreateContext();
if(NULL == c)
{
free(context);
return NULL;
}

It is called by ./TIM-VX/samples/lenet/lenet_asymu8.cc
auto context = tim::vx::Context::Create();

The context creation fails.
