[AutoTVM] Fail when search on Rasp Pi3

#1

When running tuning task, I see this error:

DEBUG:autotvm:No: 14	GFLOPS: 0.00/0.00	result: MeasureResult(costs=("Module has no function 'tvm.rpc.server.remove'",), error_no=7, all_cost=10, timestamp=1551175759.880634)	[('tile_co', [64, 8]), ('tile_oh', [7, 1]), ('tile_ow', [7, 1]), ('reorder_0', [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]), ('ann_reduce', ['none', 'none']), ('ann_spatial', ['none', 'unroll', 'none'])],direct,None,963

However both server and client has compiled with RPC feature. What could be possible reason for this error?

Your TVM runtime on the board is not the same as your server machine’s TVM. The board of TVM should be older than your server machine.
