Hello,

Thank you for this forum.
I am trying to make a object detector i tried to get the dataset from roboflow. Then i trained the mode >> converted using yolov5 to rknn to onnx >> then used convert.py to get yolov5n.rknn >> then compiled example and got the c code compiled then when i ran it it gave me this error

In details steps are here
Training Steps
1. Downloaded dataset

Code: Select all

!pip install roboflow

from roboflow import Roboflow
rf = Roboflow(api_key="fpRIiVCaZT7TFnwC1x0Y")
project = rf.workspace("data-drown").project("datn-kmi9v")
version = project.version(1)
dataset = version.download("yolov5")

2. Train dataset

Code: Select all

!python train.py --img 640 --batch 32 --epochs 10 --data /kaggle/working/yolov5/DATN-1/data.yaml --weights yolov5n.pt

3. Followed these steps to convert the best.pt to onnx and then rknn

4. Tested the folder and attached is the datn_.pt file and datn_.onnx file and yolov5.rknn

Please let me know if anything can be done i have tried all the things.

When i tried to convert my model but then it says dill not found then i needed to install this library and then it converted to onnx

Code: Select all

(yolov5) ml@ml-ts:~/yolov5$ pip show dill
Name: dill
Version: 0.3.8
Summary: serialize all of Python
Home-page: https://github.com/uqfoundation/dill

Requires: 
Required-by:

Only when i try to convert the default models of object detection yolov5 they works fine and even give error but when i installed library still they works but custom model conversion does not work

Hello,Due to the differences in development environments and actual needs, it is challenging to pinpoint the exact issues with custom model inference. In the future, we plan to develop for custom model inference to establish a universal development environment.

Currently, a common issue is the incorrect configuration of the recognition categories and the file describing the categories, coco_80_labels_list.txt.
