When running hardware tests, we can obtain a test remote via the tracker, or directly. When obtaining from the tracker, one needs to set the
TVM_TRACKER_HOSTandTVM_TRACKER_PORTenvironment variables. If unset, the test utility will try to get the hardware remote from theVTA_PYNQ_RPC_HOSTandVTA_PYNQ_RPC_PORTenvironment variables. If either PORT variables are unset, the code below causes an error since we are castingNonetointtoo early.
