You really need to make "Pre builds" for the 2.4.1 torch version because otherwise this extension IS A NIGHTMARE.

Yesterday I had this workflow working, and today this: It broke completely.

What happened? Well as explained here (https://github.com/ltdrdata/ComfyUI-Manager/issues/1136) and here (https://github.com/MrForExample/ComfyUI-3D-Pack/issues/341), anytime I install a new custom nodes (through manager), the following happen:

• Manually installed Torch (2.4.0 which corresponds to one of the pre builds avaialble) is uninstalled ,
• It is replaced with the latest torch (2.4.1 today)
• ComfyUI can even "forget" Torch exist and is unable to start. (Despite pip list showing Torch 2.4.1 being present, (maybe it is installing a version without that extra "cu121" next to the library, don't know if that any meaning)

After installing some extension and missing nodes related to other extensions (such as Comfy Essentials, which par of one of the 3D pack example workflows (https://github.com/MrForExample/ComfyUI-3D-Pack/tree/main/_Example_Workflows), 3D pack is no longer working yet again.. yet again,. Despite having done the impossible to make it work. Despite reinstalling Torch 2.4.0cu121 one million additional time.
