Convert ONNX model to Other Formats

[sharoseali]

HI, @dnth Thanks for the excellent work. Can I convert the ONNX or PyTorch model to tflite model? I roughly tried but I got the error.
After successful training and conversion, I got .pt and ONNX file. I convert the model using following command:
python3 yolov5-train/export.py --weights best.pt --include tflite --imgsz 320 --data my_data.yaml

Output:

export: data=my_data.yaml, weights=['best.pt'], imgsz=[320], batch_size=1, device=cpu, half=False, inplace=False, train=False, optimize=False, int8=False, dynamic=False, simplify=False, opset=12, verbose=False, workspace=4, nms=False, agnostic_nms=False, topk_per_class=100, topk_all=100, iou_thres=0.45, conf_thres=0.25, remove_grid=False, include=['tflite']

Hello @sharoseali , have you figured out how to convent to tflite already?

Hi @dani3l125 , no I gave up and move on, i think conversion codes should also be modified to convert sparsified model. Good luck
