Issue from rock5/rock5c/app-development/rknn_install

[machyna-vchan]

I am following the instruction https://docs.radxa.com/en/rock5/rock5c/app-development/rknn_install to run rknn models on the Radxa 5C. However, the command "sudo apt install python3-rknnlite2" failed to locate the package. Same problem also for "sudo apt install rknpu2-rk3588"

I am, however, able to run:
pip install rknn-toolkit2

When I ran:
python3 yolov5.py --model_path ./yolov5s_rk3588.rknn --target 'rk3588' --img_save
It complains the following library is not found:
/usr/lib64/librknnrt.so: cannot open shared object file: No such file or directory

So where can I install the librknnrt.so? Thanks.
