This dataset is a copy of the CoRNStack data from Nomic. This is just a reformating of the data to make it easily usable in PyLate and sentence-transformers. The data has been created from the Stack v2 by using docstring as queries and corresponding functions as target documents. Other functions has been mined to provide hard negatives. For more information about the creation of the dataset, please refer to the original paper and please considering citing them if you use this data.
Notably, this dataset has been used to perform the pre-training of the state-of-the-art late interaction LateOn-Code models. The boilerplate used to train the model using this data can be found here. For more information about the training and usage of the models, please refer to our blogpost (or model cards).
