VIM3 NPU - yolov4-tiny import model issue

Dear Khadas Team,

I use “aml_npu_sdk_6.4.0.10” to transform yolo model. When using “0_import_model.sh” to import yolo4-tiny model, the following error message appears.

Please help me to solve the issue. Thanks a lot.

~/aml_npu_sdk_6.4.0.10/acuity-toolkit/conversion_scripts$ ./0_import_model.sh

@allanwang YOLO-V4 Is already on our plan list, We will complete this in future plans, but it will take some time to adapt before use or conversion. It is still unclear where the problem is
