1. remove optimizer state and save to $HOME for example:

MODEL_DIR=/large_experiments/xlmg/models/moe/52B/xlmg.52b.fp16.bm_none.tps2048.transformer_lm_gpt2_bigger.dl24.demb1024.dffn4096.moe_w0.01.all.share.adam.b2_0.98.eps1e-08.cl0.0.lr0.0003.sqrt_world_size.wu715.dr0.0.atdr0.0.wd0.01.ms2.uf1.mu572204.s1.ngpu128

The way I test things quickly with srun:

(1) on devfair:

srun --gres=gpu:8 --partition=devaccel --nodes=1 --cpus-per-task 64 \
    --ntasks-per-node 1 --mem=400G --constraint volta32gb \
    --time="2-00:00:00" --pty /bin/zsh -l

(2) on the resultant shell:

Setup

To use it on the fair cluster gshard branch, you need the following dependencies: (from inside fairseq env, assuming cuda 11.0)

pip install -i https://test.pypi.org/simple/ bitsandbytes-cuda110 -U
pip install -U fairscale

WARNING: if you dont do this step your checkpoints will not be usable!

Setup

• git clone git@github.com:fairinternal/fairseq-py.git && cd fairseq-py && git checkout stable-emb
• if you don't have the fairseq conda env, follow these instructions
• pip install numpy==1.20. (optional, but some people needed this)
• pip install fairscale (should be > 0.3.7, as of writing)
• on FAIR cluster: pip install -i https://test.pypi.org/simple/ bitsandbytes-cuda110 -U)
• OR on AWS: pip install -i https://test.pypi.org/simple/ bitsandbytes-cuda111 -U)
