Question

First of all, thank you for your great works.
I drew the structure of the model according to yolov5l.yaml (v6.0). I'm not sure whether there are any mistakes. And I want to contribute this picture to the community and help other learners.

@WZMIAOMIAO very nice! Looks all correct.

update bottleneck, because e=1.0.

yolov5/models/common.py

Lines 127 to 139 in e6e36aa

	class C3(nn.Module):
	# CSP Bottleneck with 3 convolutions
	def __init__(self, c1, c2, n=1, shortcut=True, g=1, e=0.5): # ch_in, ch_out, number, shortcut, groups, expansion
	super().__init__()
	c_ = int(c2 * e) # hidden channels
	self.cv1 = Conv(c1, c_, 1, 1)
	self.cv2 = Conv(c1, c_, 1, 1)
	self.cv3 = Conv(2 * c_, c2, 1) # act=FReLU(c2)
	self.m = nn.Sequential(*(Bottleneck(c_, c_, shortcut, g, e=1.0) for _ in range(n)))
	# self.m = nn.Sequential(*[CrossConv(c_, c_, 3, 1, g, 1.0, shortcut) for _ in range(n)])
	def forward(self, x):
	return self.cv3(torch.cat((self.m(self.cv1(x)), self.cv2(x)), dim=1))

@glenn-jocher Next week I want to write a technical summary(markdown) about YOLOV5(v6.0). Then put it in the YOLOV5 Docs to help people learn yolov5. I don't know if you're interested. 😄

[glenn-jocher]

@WZMIAOMIAO yes that would be great! v6.0 and v6.1 use the same (current) architecture, so the docs will also apply to the latest models.

hi, I briefly summarized yolov5(v6.0). I hope you can take a look at it when you have time. #6998

Hello @WZMIAOMIAO! What do P1, P2, P3, and so on mean? And what does C3 mean? Thank you for your help! 🙏🙇‍♀️
