Pre-trained checkpoint and bert config json file

1. Location of checkpoint and bert config json file

   This MLCommons members Google Drive location contains these files.

   • TensorFlow checkpoint (tf1_ckpt) containing the pre-trained weights.
   • Config file (bert_config.json) which specifies the hyperparameters of the model.

2. Checkpoint conversion

python convert_tf_checkpoint.py --tf_checkpoint <path/to/checkpointdir_phase1/model.ckpt-28252.index> --bert_config_path <path/to/checkpointdir_phase1/bert_config.json> --output_checkpoint model.ckpt-28252.pt

Download and preprocess datasets

1. Download dataset and generate the TFRecords for training data and eval data

   BERT Wikipedia dataset preparation

2. Convert training data and eval data from TFRecords to HDF5

   TF_INPUT_DIR=<path/to/tfrecord_input_dir> HDF5_OUTPUT_DIR=<path/to/hdf5_output_dir> ./run_trans_tfrecord_to_hdf5.sh

3. 4bins training data

   We split dataset to enable data-load balacning and it can reduce communication overhead.

   Based on the sequence length distribution, split HDF5 training data into 4 part:

   part 1: 0 < sequence length <= 128

   part 2: 128 < sequence length <= 256

   part 3: 256 < sequence length <= 384

   part 4: 384 < sequence length <= 512

   The output_dir contains 4 sub-directories 128, 256, 384 and 512.

cd cleanup_scripts
python run_split_and_chop_hdf5_files.py --input_dir=<path/to/hdf5_datadir> --output_dir=<path/to/4bins_training_datadir>

Prepare the environment

• Create a virtualenv and install the required packages:

virtualenv venv -p python3.8.7
source venv/bin/activate
pip install -r requirements.txt

# Install mlperf-logging Python package
git clone https://github.com/mlperf/logging.git mlperf-logging
pip install -e mlperf-logging

# Install apex
git clone https://github.com/NVIDIA/apex.git
cd apex
git reset --hard d06404fecab73f152c6cbb89ac2c2e9b7fc24124
git submodule update --init --recursive
git apply ../patch_for_mlperf_trining_v1.1_by_samsung.patch
pip install -v --disable-pip-version-check --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" --global-option="--distributed_adam" --global-option="--distributed_lamb" --global-option="--bnp" --global-option="--xentropy" --global-option="--fast_layer_norm" --global-option="--deprecated_fused_adam"  --global-option="--fmha"  --global-option="--fast_multihead_attn" ./
