Fit uses total 32.2 GB VRAM
Fit shouldnt crash it shows you have 40 GB
Fget a fresh config from the zip file
Fset only your training folder and model file paths
ZAlso helps to close all applications and disable hardware acceleration for browser
Zlet me reboot and do a stress test on the profile

LYou can also temporarily enable the CUDA policy to use shared memory. And then calculate how much VRAM is missing because the CUDA error lies about the VRAM needed.
T
TIt actually goes up to 38.4/39.9GB just before it crashes.
Fah wait
Fhow much RAM you have?
Fphysical RAM
T64GB - it stays on first epoch step1. slowing climbing up to 38.4 and just as it s about to do first step. it gives cuda out of memory
Fok it should work
Fyou are using base FLUX model right?
F23.8 gb
Fbatch size 1 right?
Fit uses 32 gb VRAM
Fcombined
Tyes and batch 1 according to clean 8GB config
Fdid you set accelerate?
Tonly in the config.. but i noticed config shows fp16 instead ofbf16?
Fok it should be bf16
Fdoesnt work?
T
Fno not that one
Faccelerate
Fit is accurate
Fwell i dont know what else can be made need further debug. but your gpu also older gen i wonder if that makes difference
Fprobably best to rent a machine on massed compute
Tit was working before. I don't understand wht changed with the recent release 
Ftrain and use on your computer
Fyou can use older
Fjust make fresh install
Fdont run torch 2.5
Fit will stay as torch 2.4.1
Tit ran on torch 2.5 pre-release or beta..
Tis there a way to get that again?
Fah i see
Fit was release candidate
Fi dont know if you can get
TYeah around Config v6/v7 timeframe. everything was working. with torch 2.5 dev I updated to V9 with torch release, and it stopped working
