Forums - How to convert yolov4.onnx to DLC file on SNPE

Hi, I'm trying to convert yolov4.onnx to dlc file. 

first, I got yolov4.onnx from Github.

https://github.com/onnx/models/tree/master/vision/object_detection_segme...

second, I am trying to covert this ONNX file to DLC file using this command :

snpe-onnx-to-dlc --input_network yolov4.onnx --output_path yolov4.dlc

I am getting following error:

Encountered Error: Negative/placeholder dimensions is not supported.Expected shape: [0, 416, 416, 3] > 0

Note: Dynamic input batch_size not supported. Use --input_dim command to provide a static batch value
