Getting Started

Environment Requirements

pytorch==1.7.0 
cudatoolkit=11.1
datasets==1.18.3
transformers==4.16.2
tensorboard==2.8.0
tree-sitter==0.19.0;
nltk==3.6.7;
scipy==1.5.4;

To setup the environment. Please uncomment line 35 and 36 (or run those code in your shell).

bash run setup.sh

Download and preprocess the training data

cd scripts/pretraining;
bash process_data.sh

Data processing takes several parameters. These parameters are passed through a configuration json file. The configuration file should be in configs/pretraining/data_config directory.

Pretrain the model

cd scripts/pretraining;
bash train.sh <EXPERIMENT_NAME> <GPUS>

Adjust the per_device_train_batch_size and gradient_accumulation_steps and number of GPUS using to get the final effective batch size in the training arguments json file. per_device_train_batch_size * gradient_accumulation_steps * number of gpus. We use distributed training to pre-train.

We reused source code from various open source code repositories

1. CodeT5
2. Microsoft CodeXGLUE Out sincere thanks to the authors of these repositories for open-sourcing their work.
