Need help with conversion to ONNX

[surajs52]

Hey @foolwood, i need help with conversion to ONNX format. My python script using torch.onnx.export() for conversion looks like this:

from tools.test import * #from siammask.models import Custom from custom import Custom

parser = argparse.ArgumentParser(description='PyTorch Tracking Demo')

parser.add_argument('--resume', default='', type=str, required=True, metavar='PATH',help='path to latest checkpoint (default: none)') parser.add_argument('--config', dest='config', default='config_davis.json', help='hyper-parameter of SiamMask in json format') #parser.add_argument('--base_path', default='../../data/tennis', help='datasets') #parser.add_argument('--cpu', action='store_true', help='cpu mode') args = parser.parse_args()

device = torch.device('cuda' if torch.cuda.is_available() else 'cpu') torch.backends.cudnn.benchmark = True

cfg = load_config(args) siammask = Custom(anchors=cfg['anchors'])

siammask.load_state_dict(torch.load('SiamMask_DAVIS.pth')["state_dict"])

siammask.eval().to(device) siammask.half()

template = torch.randn(1, 3, 127, 127).to(device).half() search = torch.randn(1, 3, 255, 255).to(device).half() label_cls = torch.randn(1, 1, 5).to(device).half() input_dict = {'template': template, 'search': search} #, 'label_cls': label_cls}

torch.onnx.export(siammask, input_dict, "SiamMask_DAVIS_half_test.onnx", input_names=['template', 'search'], opset_version=11, do_constant_folding=True, verbose=True, output_names=['rpn_pred_cls', 'rpn_pred_loc', 'pred_mask'], dynamic_axes={'search': {0: 'batch_size'}, # if you want batch size to be dynamic 'rpn_pred_cls': {0: 'batch_size'}, 'rpn_pred_loc': {0: 'batch_size'}, 'pred_mask': {0: 'batch_size'}})

The output looks like this: [2024-02-14 15:40:21,552-rk0-features.py# 66] Current training 0 layers:

[2024-02-14 15:40:21,554-rk0-features.py# 66] Current training 1 layers:

To be specific, i need help figuring out the exact set of input and output parameters for torch.onnx.export() to perform the conversion.
