How it works

Environment

  1. Create a virtual environment with python3.6 installed(virtualenv)
  2. git clone --recursive https://github.com/magnumresearchgroup/Magnum-NLC2CMD.git
  3. use pip3 install -r requirements.txt to install the two requirements files.

Data pre-processing

  1. Run python3 main.py --mode preprocess --data_dir src/data --data_file nl2bash-data.json and cd src/model && onmt_build_vocab -config nl2cmd.yaml -n_sample 10347 --src_vocab_threshold 2 --tgt_vocab_threshold 2 to process raw data.
  2. You can also download the Original raw data here

Train

  1. cd src/model && onmt_train -config nl2cmd.yaml
  2. Modify the world_size in src/model/nl2cmd.yaml to the number of GPUs you are using and put the ids as gpu_ranks.
  3. You can also download one of our pre-trained model here

Inference

  1. onmt_translate -model src/model/run/model_step_2000.pt -src src/data/invocations_proccess_test.txt -output pred_2000.txt -gpu 0 -verbose

Evaluate

  1. python3 main.py --mode eval --annotation_filepath src/data/test_data.json --params_filepath src/configs/core/evaluation_params.json --output_folderpath src/logs --model_dir src/model/run --model_file model_step_2400.pt model_step_2500.pt

  2. You can change the gpu=-1 in src/model/predict.py to gpu=0, and replace the code in src/model/predict.py accordingly with the following code for faster inference time

    Show details 

    invocations = [' '.join(tokenize_eng(i)) for i in invocations]
translated = translator.translate(invocations, batch_size=n_batch)
commands = [t[:result_cnt] for t in translated[1]]
confidences = [ np.exp( list(map(lambda x:x.item(), t[:result_cnt])) )/2 for t in translated[0]]
for i in range(len(confidences)):
    confidences[i][0] = 1.0

Metrics

Accuracy metric

𝑆𝑐𝑜𝑟𝑒(𝐴(𝑛𝑙𝑐))=max𝑝∈𝐴(𝑛𝑙𝑐)𝑆(𝑝) if ∃𝑝∈𝐴(𝑛𝑙𝑐) such that 𝑆(𝑝)>0;

𝑆𝑐𝑜𝑟𝑒(𝐴(𝑛𝑙𝑐))=1|𝐴(𝑛𝑙𝑐)|∑𝑝∈𝐴(𝑛𝑙𝑐)𝑆(𝑝) otherwise.

Reproduce

  1. We used 2x Nvidia 2080Ti GPU + 64G memory machine running Ubuntu 18.04 LTS
  2. Change the batch_size in nl2cmd.yaml to the largest your GPU can support without OOM error
  3. Train multiple models by modify seed in nl2cmd.yaml, you should also modify the save_model to avoid overwrite existing models.
  4. Hand pick the best performed ones on local test set and put their directories in the main.py
