cd ColossalAI

pip install --no-cache-dir .

Prepare dataset from JSON file.

# install nltk
pip install --upgrade --no-cache-dir nltk

python -c "import nltk; nltk.download('punkt')"

python process_data.py \
    --data-path /PATH/TO/JSON/FILE \
    --vocab-file /PATH/TO/VOCAB/FILE \

    --seq-len 512

Colossal-AI Usage

Run benchmark

Prepare your configuration file such as configs/bert_config_tp1d.json
Locally:

torchrun --nproc_per_node=NUM_GPUS \
    run.py \
    --config configs/bert_config_tp1d.json \
    --data-path /PATH/TO/DATASET/ \
    --vocab-file /PATH/TO/VOCAB/FILE

On platform: submit colossal_bert.sh.
