当我将“.pth”模型从 PyTorch 转换为 ONNX 时，会发生类似错误Unexpected keys and missing keys。
这是我的模型：
1 import torch
2 import torch.onnx
3 from mmcv import runner
4 import torch.`enter code here`nn as nn
5 from mobilenet import MobileNet
6 # A model class instance (class not shown)
7 md=MobileNet(1,2)
8 model = md
9 device_ids = [0,2,6,7,8]
10 model = nn.DataParallel(model,device_ids)
11 #torch.backends.cudnn.benchmark = True
12 # Load the weights from a file (.pth usually)
13 runner.load_checkpoint(model,'../mmdetection- master/work_dmobile/faster_rcnn_r50_fpn_1x/epoch_60.pth')
14 #model = MMDataParallel(model, device_ids=[0])
15 #state_dict=torch.load('../mmdetection-master/r.pkl.json')
16 # Load the weights now into a model net architecture defined by our class
17 #model.load_state_dict(state_dict)
18 #model = runner.load_state_dict(state_dict)
19 model=runner.load_state_dict({k.replace('module.',' '):v for k,v in state_dict['state_dict'].items()})
20 # Create the right input shape (e.g. for an image)
21 dummy_input = torch.randn(1, 64, 512, 256)
22
23 torch.onnx.export(model, dummy_input, "onnx_model_name.onnx")
这是错误：
