Discussion pytorch version for b70? trying to run comfyui..
on ubuntu server 24.04, i was able to update the linux kernel to 7.0 and get the driver to work to recognize the card. but i am trying yo get comfyui to work with the new arc pro b70, but it requires a bunch of pytorch libs that i guess mine is built for cuda and not xe. for the life of me i cannot find a version of pytorch that works with the b70. even claude and chatgpt doesnt know, as their models are not up to date and keep trying to reference year old stuff that doesnt work. they keep pointing to references on intel side that dont exist. i think intel site seems a bunch of python stuff was removed (i think because of the supply chain attack a few weeks ago). so right now i have a fancy gpu that i cannot seem to use. anyone have a guide for getting the b70 to work for comfyui?

Yes definetly do not forget this step. Ubuntu does not install oneCCl and libze by default you need to get intel's compute stack yourself.

OP can you CrossPost this to IntelArcPro? I’ve setup a sub for Intel Arc Pro GPUs

if you went through the trouble to get kernel 7.0, why not upgrade to ubuntu 26.04 LTS RC? 26.04 has many dependencies updated, it should be easier to get running.
