Cannot always add outputs

[mcusgithub]

Sometimes, output(s) cannot be added / saved.

To reproduce:

• Load squeezeNet (link provided in the help)
• Delete the "softmaxout_1" output = Ok
• Select the "softmaxout_1" node
• Click "Add Output" = nothing happens = no output is created

This happens with other models (without deleting the output first as above; this is just to show how to reproduce the issue). It seems to happen when the selected node is a 'leaf' = last one on a branch.

Thank you for your help.

• Workaround: Load / Delete node / Save / Re-load onnx / Add Output / Save model again.
• This workaround is also required to get the "Add Node" functionality to work properly in some cases

@mcusgithub Thanks for reporting! The problem has been reproduced and I will try to fix it soon.

• 在yolov7 onnx 模型中， 删除concat节点以及后面的output，可以download 模型
• 但是添加输出的时候，无法download模型，输出设置batch 数也没有响应

@WangFengtu1996 谢谢反馈，该问题可能和#72 原因相同。请使用最新代码，看看问题是否还存在。同时也可查看终端，显示的报错信息，可以帮助定位问题。

@mcusgithub Hello, I have updated the code to fix the adding output issue (after a very long delay :sweat_smile:). You can update the code to the latest version, and see whether it works.

This issue is going to be closed due to inactivity. Free free for more discussions if problems still exist.

@ZhangGe6 Does not seem to work still (tested on YOLOv8n), and the initial workaround does not work anymore.

@mcusgithub Thanks for reporting. As discussed in #75, with the latest code, the "adding output" function should be more robust than before. I have tested both the squeezenet and YOLOv8n. Adding output for both models works as expected.
