I want to convert the yolov8-obb model which trained myself to RKNN,But it donesn't works?

[Mcaft]

When I convert it,It warn me this :
W build: Show op fuse match nodes:
Rule: reduce_reshape_op_around_concat
Subgraph:
Op type: Concat
Op name: /model.22/Cos_output_0_concat
Input:
/model.22/Cos_output_0_rs : [1, 1, 1, 8400]
/model.22/Sin_output_0_rs : [1, 1, 1, 8400]
/model.22/Cos_output_0_rs : [1, 1, 1, 8400]
Output:
/model.22/Cos_output_0_concat-rs : [1, 3, 1, 8400]
Attribute:
axis : 1

W You can add disable_rules=['reduce_reshape_op_around_concat'] in rknn.config() to temporarily disable the error rule!
