I am trying to run benchmark apps under tvm/apps/benchmark, however, I got following errors.

➜  benchmark git:(master) python arm_cpu_imagenet_bench.py --rpc-key android --port 9090

Both the apk and sample benchmark code are pulled from the latest commit. Can anyone help on this?

All this says is that loading of the module on the device has failed. Check logcat messages, there should be more details there.

Hi Huifeng, after upgrading the Android RPC to latest version, the issue no longer appears in my environment.
