OOM on two 80GB GPUs

[kyleliang919]

accelerate launch finetune.py \
    --output-dir output/mistral-yarn-7b-64k \
    --model mistralai/Mistral-7B-v0.1 \
    --architecture mistral \
    --scaling-factor 2 \
    --max-position-embeddings 16384 \
    --dataset emozilla/yarn-train-tokenized-8k-mistral \
    --sliding-window-attention-schedule 4096 \
    --lr-schedule constant \
    --learning-rate 0.000001 \
    --max-train-steps 1000

Both with or without lora hits the OOM error, this is on only 8K sequence length, so memory consumption should be around 4x smaller compared with training on 16K sequence length.

accelerate is configured to use two GPU and FSDP.

I also encountered this problem, have you solved it now? @kyleliang919 @edisonzf2020

unfortunately no, I think you probably need at least 320 GB to handle this run.

thank you for your reply.
I have 4xA100, but there is a process on each GPU, so it's still OOM, like 2xA100, I don't know how to configure. QAQ
