[SOLVED] 关于 RK3399-cannot find for target=llvm


[10:07:44] src/nnvm/legacy_json_util.cc:217: Symbol successfully upgraded!
Cannot find config for target=llvm -device=arm_cpu -model=rk3399 -target=aarch64-linux-gnu -mattr=+neon, workload=(‘conv2d’, (1, 3, 112, 112, ‘float32’), (64, 3, 3, 3, ‘float32’), (2, 2), (1, 1), (1, 1), ‘NCHW’, ‘float32’). A fallback configuration is used, which may bring great performance regression.



please check your TVM version, I think you probably used the old version.


The warning means some operators are not tuned with autotvm.
You can ignore it. However, if you want good performance, you can follow autotvm tutorials to tune it.
