Official download links: google albert

Adapt to this version，download pytorch model (google drive):

v1

• albert_base_v1.zip
• albert_large_v1.zip
• albert_xlarge_v1.zip
• albert_xxlarge_v1.zip

v2

• albert_base_v2.zip
• albert_large_v2.zip
• albert_xlarge_v2.zip
• albert_xxlarge_v2.zip

Fine-tuning

１. Place config.json and 30k-clean.model into the prev_trained_model/albert_base_v2 directory. example:

├── prev_trained_model
|  └── albert_base_v2
|  |  └── pytorch_model.bin
|  |  └── config.json
|  |  └── 30k-clean.model

2．convert albert tf checkpoint to pytorch

python convert_albert_tf_checkpoint_to_pytorch.py \
    --tf_checkpoint_path=./prev_trained_model/albert_base_tf_v2 \
    --bert_config_file=./prev_trained_model/albert_base_v2/config.json \
    --pytorch_dump_path=./prev_trained_model/albert_base_v2/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 albert model
