A fallback configuration is used, which may bring great performance regression.

Is there anyone can help me? Thanks in advance for any answer.@merrymercy

If you are using the out-of-the-box NNVM autotvm tuning scripts, you might need to add the conv2d transpose operator to the operator types to tune. Try adding nnvm.sym.conv2d_transpose to this argument.
