【Auto Scheduler mali gpu】 Cannot get remote devices from the tracker

#1

tvm version：v0.13.dev0

I want to tune model for mali gpu follow this guide Auto-scheduling a Neural Network for mali GPU — tvm 0.13.dev0 documentation

And I can successfully get gpu hardware params by:

remote = request_remote(device_key, “127.0.0.1”, 9190)

dev = remote.cl()

But when tune_and_evaluate raise an error: RuntimeError: Cannot get remote devices from the tracker. Please check the status of tracker by ‘python -m tvm.exec.query_rpc_tracker --port [THE PORT YOU USE]’ and make sure you have free devices on the queue status.

The error will not raise for the cpu and the rpc setting checked is ok.

#2

Then I comment out check_remote and run with the following errors: opencl_device_api.cc:508: Warning: No OpenCL device

I have already check my platform opencl by clinfo, and can get the right information about the gpu.

The python interface as following can also get the hardware params remote = request_remote(device_key, “127.0.0.1”, 9190)

dev = remote.cl()

The tvm_runtime library was cross compiled on my host machine.
