Whenever I update comfy using comfy manager, some custom nodes getting import failed. I am not sure what's the issue and how to help developer reproduce it. Please help.
Above are screenshots for last three update/try to fix and Uninstall attempts for fixing issue.

Some of the custom nodes you've installed are causing package dependency conflicts, particularly when installing certain outdated versions of the "transformers" and "diffusers" packages.

It seems that ComfyUI_Seg_VITON is the main problematic node. This custom node is consistently installing lower versions of transformers and diffusers.

AssertionError: diffusers>=0.25.0 requirement not satisfied. Please install correct diffusers version.

Cannot import D:\000AI\ComfyUI\ComfyUI\custom_nodes\ComfyUI-layerdiffusion module for custom nodes: diffusers>=0.25.0 requirement not satisfied. Please install correct diffusers version.

The above exception was the direct cause of the following exception:

I would recommend disabling ComfyUI_Seg_VITON and reinstalling transformers and diffusers with the latest versions.
You can install them via Instal PIP packages menu.

I removed all possible custom nodes that I have installed recently.
Even after that, I see some issue with listing nodes

Here what is failed in terminal is not listed here in UI, but a next entry is appearing. For example ComfyUI-layerdiffusion has failed in terminal but in UI it shows ComfyUI-VideoHelperSuite and human-parser-comfyui-node has failed in terminal but in UI it's ComfyUI-Crystools. However, both ComfyUI-Crystools and ComfyUI-VideoHelperSuite nodes are usable in comfy.

Also it would be great if you make one tutorial video on installing package using pip package installer in comfy :) for non developer people like me

You need to check the teminal message.
Also, I don't understand the situation where the ComfyUI-Manager fails and but the dialog pops up. Could it be due to duplicate installations?

The log simply indicates a failure in import, so it's of no help in diagnosis as it's just a symptom. The logs indicating why the failure occurred earlier on are what's important.

That's exactly what I'm saying. It simply shows that there was a failure in import, without any information about why it failed. That's why I always request the full log.

Issue is not with fail, issue is listing wrong node name in UI.
The fail node is different and the node listed in comfy manager list is different.
