[bug] Missing node types

[al3dv2]

After the full installation I have a error :

[maurorilla]

I got the same issue, it doesn't find in my case the 'easy_nodes' Traceback (most recent call last):
File "Q:\ComfyUI\ComfyUI\nodes.py", line 2026, in load_custom_node
module_spec.loader.exec_module(module)

File "Q:\ComfyUI\ComfyUI\custom_nodes\ComfyUI-LTXVideo\nodes_registry.py", line 4, in
from easy_nodes import initialize_easy_nodes
ModuleNotFoundError: No module named 'easy_nodes'

and then fails to load

The problem come from the workflow examples on the github main page here's workflows that works : https://comfyanonymous.github.io/ComfyUI_examples/ltxv/?ref=blog.comfy.org

I'm getting the same thing with both workflows. For me it seems to stem from an error that occurs when running pip install -r requirements.txt

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: subprocess-exited-with-error

Which is weird, because cmake is definitely installed:

PS D:\ComfyUI\custom_nodes\ComfyUI-LTXVideo> cmake --version
cmake version 3.31.0

PS D:\ComfyUI\custom_nodes\ComfyUI-LTXVideo> pip install cmake --upgrade
WARNING: Ignoring invalid distribution ~uggingface-hub (C:\Python312\Lib\site-packages)
Requirement already satisfied: cmake in c:\python312\lib\site-packages (3.31.0.1

Maybe that warning is about the invalid distribution is something?

[al3dv2]

I think you need to install comfyui native node like explain here https://blog.comfy.org/ltxv-day-1-comfyui/

[al3dv2]

there's a problem with the custom nodes for sure

[al3dv2]

I really want to use the vid2vid but there's no example with the native node :/

[ahokinson]

Experiencing something similar myself. Different nodes missing for all workflows. Followed instructions as written.

[MelvinMik]

if u cant install the wheel set the recommended python version on top of ur paths and update comfy

[cchance27]

Update your ComfyUI to have the native nodes, that said, this custom_nodes is another version of the various nodes but i maintained by the model creator. They don't conflict so no issue you can always install this custom-node set and then also update your comfyui to latest version, they only added support last night i believe

[ahokinson]

Circling back to say that for some reason, I was on a different branch. Moving back to master fixed this for me.

[kvochko]

Hi al3dv2! We are struggling to reproduce this. Could you please attach the output of pip list here?

[al3dv2]

Hi Andrew Kvochko (@kvochko) its because when I install LTX I have this error #4

[al3dv2]

How I get the output of pip list ?
