The dataset generation failed because of a cast error
Error code: DatasetGenerationCastError
Exception: DatasetGenerationCastError
Message: An error occurred while generating the dataset
All the data files must have the same columns, but at some point there are 6 new columns ({'moment_coefficient', 'id', 'drag_coefficient', 'rear_lift_coefficient', 'front_lift_coefficient', 'lift_coefficient'}) and 9 missing columns ({'status_code', 'submission_time', 'Drag', 'current_time', 'Rear Lift', 'Moment', 'task_id', 'Lift', 'Front Lift'}).
This happened while the json dataset builder was generating data using
hf://datasets/rvalerio/windtunnel/data/train/1n8qi4jeny5rgajbwma2bdscy/simulation_metadata.json (at revision e191f3796beb21508755c2b788adc2b89c324c19)
Please either edit the data files to have matching columns, or separate them into different configurations (see docs at https://hf.co/docs/hub/datasets-manual-configuration#multiple-configurations)

Wind Tunnel Dataset
Overview
This repository contains a dataset for wind tunnel simulations, organized into three main subsets: training, validation, and test. Each subset includes simulation files in various formats necessary for analysis and model training.
File Descriptions
- metadata.json: Includes metadata information of the simulation.
- input_mesh.obj: OBJ file with the input mesh.
- openfoam_mesh.obj: OBJ file with the OpenFOAM mesh.
- pressure_field_mesh.vtk: VTK file with the pressure field data.
- streamlines_mesh.ply: PLY file with the streamlines.
Usage
To use the dataset, clone the repository and navigate to the data directory. Each subset can be used for training, validating, or testing your models.
Downloading the Dataset
You can download the dataset from the Hugging Face Hub using the following code:
from huggingface_hub import snapshot_download
dataset_name = "rvalerio/windtunnel"
# Download the entire dataset
snapshot_download(repo_id=dataset_name)
# Download to a specific directory
snapshot_download(repo_id=dataset_name, local_dir="windtunnel_dataset")
# Download only specific files
snapshot_download(allow_patterns=["*/input_mesh.obj"], repo_id=dataset_name)
snapshot_download(ignore_patterns=["*/input_mesh.obj"], repo_id=dataset_name)
