@masahi Have you solved the problem？I solved the problem of error reporting of LocalRunner according to the above method, but autotvm GFLOPS is 0.00.
result: MeasureResult(costs=(FileNotFoundError(2, ‘系统找不到指定的文件。’, None, 2, None),), error_no=2, all_cost=0.055005550384521484,
....etc
But I run it on linux,It works very well！
#--------------------------------------------------------------- The latest code also have an error:
......
"..\multiprocessing\reduction.py", line 60, in dump
ForkingPickler(file, protocol).dump(obj)
Can't pickle local object '_wrap_build_func.<locals>._wrapped'
