Fine-tuning

１. Place config.json and vocab.txt into the prev_trained_model/mobilebert directory. example:

├── prev_trained_model
|  └── mobilebert
|  |  └── pytorch_model.bin
|  |  └── config.json
|  |  └── vocab.txt

2．convert mobilebert tf checkpoint to pytorch

python convert_mobilebert_tf_checkpoint_to_pytorch.py \
    --tf_checkpoint_path=./prev_trained_model/mobilebert \
    --mobilebert_config_file=./prev_trained_model/mobilebert/config.json \
    --pytorch_dump_path=./prev_trained_model/mobilebert/pytorch_model.bin

The General Language Understanding Evaluation (GLUE) benchmark is a collection of nine sentence- or sentence-pair language understanding tasks for evaluating and analyzing natural language understanding systems.

Before running anyone of these GLUE tasks you should download the GLUE data by running this script and unpack it to some directory $DATA_DIR.

3．run sh scripts/run_classifier_sst2.shto fine tuning mobilebert model

Result

Performance of MobileBert on GLUE benchmark results using a single-model setup on dev:

	Cola	Sst-2	Sts-b
metric	matthews_corrcoef	accuracy	pearson
mobilebert	0.5837	0.922	0.8839
