export p7 to onnx format

[JobCollins]

I am runing this

python3 models/export_onnx.py --weights ./weights/yolov4-p7.pt --img-size 1536

to convert a p7 to onnx format but it times out. Here is the resulting output:

Namespace(batch_size=1, img_size=[1536, 1536], weights='./weights/yolov4-p7.pt')
Fusing layers... Model Summary: 503 layers, 2.87475e+08 parameters, 2.7862e+08 gradients

Starting ONNX export with onnx 1.9.0...
^C

There is an automatic interrupt. What can I do to get the conversion working.
