Hi Ultralytics Community! First, I want to apologize if there is any typo. This is not a really matter problem since I 've trained the model without getting a problem. But, I want to understand the lastest version of Yolo, Yolov11, as well as its architecture. So far, I’ve searched in the files o…

Hi there! :blush: No need to apologize—your question is insightful, and it’s great to see your interest in understanding YOLO11’s architecture, especially the C3k2 block. Let’s dive into it! Understanding the C3k2 Block: As you’ve noticed, the C3k2 block is part of the YOLO11 architecture, defined …

You can see the forward function. In [5]: model.model.model[2].forward?? Signature: model.model.model[2].forward(x) Source: def forward(self, x): """Forward pass through C2f layer.""" y = list(self.cv1(x).chunk(2, 1)) y.extend(m(y[-1]) for m in self.m) return sel…

I can tell you that I rely on answers from Toxite, so I would you encourage you to believe him. If you still don’t, then you can always run the forward method yourself of a dummy tensor to verify what the output looks like.

Hi Sankyuu, I just came across this post. The C3k2 block can definitely be tricky, especially since it has two different versions depending on whether c3k=True or False. I’ve included the diagrams I created for my YOLO11 video series, which helped me better understand and visualize these blocks (a…

Hi @Sankyuu , and a big thank you to @marctornero for sharing those excellent diagrams! That’s a great question about the C3k2 block’s architecture. It looks like there might be a small misunderstanding in reading the model summary. Based on your screenshot, both cv1 and cv2 inside the C3k2 block a…

Dear Toxite!
Thanks for your help, your answer may be the key for me to know further. Now, I’m not sure about the true answer is, but your advice will be helpful to me to explore the architecture of Yolov11.
Best regards
