Installation/Import Fails

[jadanduffin]

Cant get anything to work. Ive loaded form the zip and from within comfy and Im constantly getting errors.

Here is the issue form the custom node importer. Has a 'Import Failed red button above the name.

Error message occurred while importing the 'ComfyUI-LTXVideo' module.

Traceback (most recent call last):

inside comfy the errors shows Im missing node packs...

Missing Node Packs (2)
This workflow uses custom nodes you haven't installed yet.

To install missing nodes, first run pip install -U --pre comfyui-manager in your Python environment to install Node Manager, then restart ComfyUI with the --enable-manager flag.

Finally- there is JUST a nightly version, there are no previous releases to fall back on...

I just ran into this issue, my issue was Kornia 0.8.3 was installed by ComfyUI-LTXVideo is expecting an older API. I ran these two commands inside my venv:

pip uninstall -y kornia kornia-rs
pip install kornia==0.7.3

Restarted ComfyUI and the error went away and everything seemed to work.

I posted a fix for the issue here.

I re-downloaded and added the folder and Im still getting the errors.... Not sure what to do, but nothing has changed. Do I need to rename the folder and remove '-master' to the folder name? I have comfy manager installed, yet its saying I need to download it. I just updated it too. Here are some images that may shed some light on things...

I'm in the same boat as the OP.
I deleted what I already had for LTXVideo.

Tried copying the link to your fork and installing through ComfyUI manager.

I also tried cloning your fork and unzipping into the custom_nodes folder, redid the requirements.txt.

Comfy Manager still doesnt register LTXVideo being install, and the nodes in my workflow are still red.
Any help would be appreciated!

That fork is old. In case they made any new updates or anything, the only thing new there is the one text file edit, which can be done with any sort of text editor

I deleted the node folder again, installed with ComfyUI manager, changed that section of pyramid_blending.py to match yours, and I still get the 'cannot import...Either a revision or a version must be specified'

have the exactely same problem, downloaded a new workflow, installed everything new, instead of comfy ui itselt. all is at newest version, but i won't get this node and some others too. some i could add manually which were not available in the manager.

But at the end, i still miss these IC-Lora nodes....

Does anybody know what the 'Either a revision or a version must be specified'

Does anybody know what the 'Either a revision or a version must be specified' error is relating to? It's not very specific.

Is it complaining about my Python or ComfyUI version?

I couldnt see any version specifics in the requirements.
