h, I want to convert onnx model in https://github.com/Linzaer/Ultra-Light-Fast-Generic-Face-Detector-1MB/tree/master/models to rknn. in first step, when I run  ret = rknn.load_onnx(model = './version-RFB-320.onnx'), I face with this error:

It means the op 'Slice' is unsupported by rknn.
You need to change it or waiting for our implementation.

You have to update rknn-toolkit to the latest version, each new version will support more OPs.
After you trying the latest rknn-toolkit and find it is still unsupported, you can report it here with rknn-toolkit version number.

I downloaded rknn_toolkit-1.3.0-cp36-cp36m-linux_aarch64.whl for install rknn-toolkit-1.3.0. in but in installation occurred errors:

Fedora or debian10？ If in debian10, just using 'pip3 install rknn'

Finaly, I can resolve problems in installing rknn-toolkit 1.3.0 and installed it.
but again in loading onnx model , this error occurred:
