File Description

data.zip

This archive contains the main dataset used for Text2Loc_v2.

It includes the processed data required for training and evaluation. Users who would like to reproduce the main results or train models on the full dataset should use this file.

Please unzip this archive before running the training or evaluation scripts.

model_checkpoints.zip

This archive contains the released model checkpoints.

These checkpoints can be used for evaluation, inference, or as initialization for further research. Please refer to the main GitHub repository for the expected checkpoint paths and loading instructions.

Recommended Usage

For regular use, please download and extract:

data.zip
model_checkpoints.zip

Please make sure the extracted file paths match the configuration used in the GitHub repository.

Notes

Additional lightweight files may be present in this repository for internal review or demonstration purposes. They are not required for normal usage, formal training, evaluation, or result reproduction.
