Are you ready to dive into the world of structured knowledge grounding? This blog will guide you through the UnifiedSKG framework, which combines 21 SKG tasks into a unified format, making it easier to conduct systematic and compatible research. Whether you’re a seasoned developer or new to this space, we’ll help you understand how to get started using UnifiedSKG.

What is Structured Knowledge Grounding?

Structured Knowledge Grounding (SKG) allows systems to perform tasks like semantic parsing over databases and knowledge bases. However, traditional approaches often treated these tasks separately, creating a need for a unified solution. Enter UnifiedSKG, which transforms how we interact with and leverage structured knowledge!

How to Get Started with UnifiedSKG

Cloning the Repository

To initiate your journey, you’ll need to clone the UnifiedSKG repository. Ensure you do this recursively to include all dependencies:

git clone --recurse-submodules git@github.com:HKUNLPUnifiedSKG.git

Setting Up Your Environment

A well-configured environment is crucial for running UnifiedSKG smoothly. Here’s how to set it up:

conda env create -f py3.7pytorch1.8.yaml
conda activate py3.7pytorch1.8new
pip install datasets==1.14.0
pip install torch==1.8.0+cu111 torchvision==0.9.0+cu111 torchaudio==0.8.0 -f https://download.pytorch.org/whl/torch_stable.html

Depending on your CUDA version, choose the appropriate installation command. This setup creates the required environment for using UnifiedSKG.

Training Models

Once your environment is ready, you can start training models with just a few commands. For example, to finetune the T5-base model on your specific dataset, you would use:

python -m torch.distributed.launch --nproc_per_node 4 --master_port 1234 train.py --seed 2 --cfg SalesforceT5_base_finetune_wikitq.cfg --run_name T5_base_finetune_wikitq --logging_strategy steps --logging_first_step true --logging_steps 4 --evaluation_strategy steps --eval_steps 500 --metric_for_best_model avr --greater_is_better true --save_strategy steps --save_steps 500 --save_total_limit 1 --load_best_model_at_end --gradient_accumulation_steps 8 --num_train_epochs 400 --adafactor true --learning_rate 5e-5 --do_train --do_eval --do_predict --predict_with_generate --output_dir outputT5_base_finetune_wikitq --overwrite_output_dir --per_device_train_batch_size 4 --per_device_eval_batch_size 16 --generation_num_beams 4 --generation_max_length 128 --input_max_length 1024 --ddp_find_unused_parameters true

For resuming training, simply remove the --overwrite_output_dir flag!

Loading Weights

Need to load pre-trained weights? You can easily do so by following the instructions on the official project page or using the demo provided in Google Colab.

Understanding the Code Structure

The UnifiedSKG codebase is modularized into various directories, which help in organizing tasks, configurations, models, and utilities.

• configure: Holds configuration files for experiments and tasks.
• metrics: Contains code for model evaluation.
• models: Houses the actual model implementations such as T5 and BART.
• seq2seq_construction: Responsible for constructing the input-output sequences.

This structure makes it simpler to extend the framework by adding new tasks or models.

Troubleshooting Tips

While working with UnifiedSKG, you may encounter issues. Here are a few common solutions:

• Incorrect dependencies: Ensure that all dependencies are correctly installed as per the setup instructions.
• Environment Issues: Use conda to manage environments, ensuring no conflicts arise.
• Logging Configuration: If logs are not appearing, double-check your WandB setup is correctly configured.
