The imported library version is too old

During installation, there are various version conflicts. If ignore these conflicts, many errors will be reported, the plugin seems impossible to use

I had the same problem and after I installed LTXVideo, so many custom nodes failed to import. I opened manager and clicked (Try fix) and everything works fine now. I do not think there is a problem about this. CogVideox and PyramidFlow are working fine beside LTXVideo, if this is your concern

I finally installed it, but run it will get this error, any suggestions?
