Hi @thkim
If you update your from the above githhub link and my change on the export_library, then let me check few more.
It is not a connection issue, as you see GFLOPS (always 0.00/ 0.00 GFLOPS) message.
Does it every finish?
How many iteration you’ve set?
Are other testing such as this that are not using autotvm works?
Cheers, ISS
