About Yolov7-tiny Reparameterization run request

[PlutoNameless]

My trained yolov7-tiny has never been able to get normal feedback when using the official case https://github.com/WongKinYiu/yolov7/blob/main/tools/reparameterization.ipynb for reparameterization. feedback; I modified the content at model.77 based on other people's hints;

This is my code

# import
from copy import deepcopy
from models.yolo import Model
import torch
from utils.torch_utils import select_device, is_parallel
import yaml

device = select_device('0', batch_size=1)
# model trained by cfg/training/*.yaml
ckpt = torch.load('cfg/training/yolov7-tiny_training.pt', map_location=device)
# reparameterized model in cfg/deploy/*.yaml
model = Model('cfg/deploy/yolov7-tiny.yaml', ch=3, nc=80).to(device)

with open('cfg/deploy/yolov7-tiny.yaml') as f:
    yml = yaml.load(f, Loader=yaml.SafeLoader)
anchors = len(yml['anchors'][0]) // 2

# copy intersect weights
state_dict = ckpt['model'].float().state_dict()
exclude = []
intersect_state_dict = {k: v for k, v in state_dict.items() if k in model.state_dict() and not any(x in k for x in exclude) and v.shape == model.state_dict()[k].shape}
model.load_state_dict(intersect_state_dict, strict=False)
model.names = ckpt['model'].names
model.nc = ckpt['model'].nc

# reparametrized YOLOR
for i in range((model.nc+5)*anchors):
    model.state_dict()['model.77.m.0.weight'].data[i, :, :, :] *= state_dict['model.77.im.0.implicit'].data[:, i, : :].squeeze()
    model.state_dict()['model.77.m.1.weight'].data[i, :, :, :] *= state_dict['model.77.im.1.implicit'].data[:, i, : :].squeeze()
    model.state_dict()['model.77.m.2.weight'].data[i, :, :, :] *= state_dict['model.77.im.2.implicit'].data[:, i, : :].squeeze()
model.state_dict()['model.77.m.0.bias'].data += state_dict['model.77.m.0.weight'].mul(state_dict['model.77.ia.0.implicit']).sum(1).squeeze()
model.state_dict()['model.77.m.1.bias'].data += state_dict['model.77.m.1.weight'].mul(state_dict['model.77.ia.1.implicit']).sum(1).squeeze()
model.state_dict()['model.77.m.2.bias'].data += state_dict['model.77.m.2.weight'].mul(state_dict['model.77.ia.2.implicit']).sum(1).squeeze()
model.state_dict()['model.77.m.0.bias'].data *= state_dict['model.77.im.0.implicit'].data.squeeze()
model.state_dict()['model.77.m.1.bias'].data *= state_dict['model.77.im.1.implicit'].data.squeeze()
model.state_dict()['model.77.m.2.bias'].data *= state_dict['model.77.im.2.implicit'].data.squeeze()

# model to be saved
ckpt = {'model': deepcopy(model.module if is_parallel(model) else model).half(),
        'optimizer': None,
        'training_results': None,
        'epoch': -1}

# save reparameterized model
torch.save(ckpt, 'cfg/deploy/yolov7-tiny.pt')

Now it runs with the following error

Traceback (most recent call last):
  File "re.py", line 38, in <module>
    model.state_dict()['model.77.m.0.weight'].data[i, :, :, :] *= state_dict['model.77.im.0.implicit'].data[:, i, : :].squeeze()
KeyError: 'model.77.im.0.implicit'�

This has forced me to look for other ways to make progress. I see that yolov7n is a pending project in your project, do you currently have an update planned or can you help answer the questions I'm having.
Many thanks.

Hey, sorry for the delay. Have you found the solution?
