Python Script for converting Darknet/Yolov4 to Onnx and TFLite formats

I require a proficient Python developer who can create a script for me. The script should be able to convert Darknet/Yolov4 weights files to both Onnx and TFLite formats.

You can work on these 2 pre-trained models for the conversion-
https://github.com/hank-ai/darknet/releases/download/v2.0/yolov4-tiny.weights
https://github.com/hank-ai/darknet/blob/master/cfg/yolov4-tiny.cfg

And
https://github.com/hank-ai/darknet/releases/download/v2.0/yolov4.weights
https://github.com/hank-ai/darknet/blob/master/cfg/yolov4.cfg

The conversion script should work either in Colab or Kaggle's notebook.
