Onnx model not running on jetson

I have converted a keas model to onnx model through keras2onnx library and then I was trying to run onnx model on jetson through this command:
trtexec --onnx=/home/model.onnx --saveEngine=/home/model.engine

Model file: keras-recognize-model.onnx - Google Drive

I am getting error:

[libprotobuf ERROR google/protobuf/text_format.cc:298] Error parsing text-format onnx2trt_onnx.ModelProto: 1:1: Invalid control characters encountered in text.
[libprotobuf ERROR google/protobuf/text_format.cc:298] Error parsing text-format onnx2trt_onnx.ModelProto: 2:11: Invalid control characters encountered in text.
