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

Development
#1

我运行tvm的例程都会出现如下问题：
[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.

请问怎么解决

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.
