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 ({'uid', 'inv_dist_std', 'px_world', 'dist_std', 'pz_world', 'py_world'}) and 27 missing columns ({'ty_world_device', 'angular_velocity_x_device', 'device_linear_velocity_y_device', 'tz_ecef_device', 'tz_world_device', 'gravity_y_world', 'utc_timestamp_ns', 'qw_ecef_device', 'device_linear_velocity_x_device', 'ty_ecef_device', 'tracking_timestamp_us', 'tx_world_device', 'qw_world_device', 'gravity_z_world', 'geo_available', 'quality_score', 'tx_ecef_device', 'qz_ecef_device', 'angular_velocity_y_device', 'device_linear_velocity_z_device', 'qx_ecef_device', 'qy_ecef_device', 'qy_world_device', 'qx_world_device', 'qz_world_device', 'angular_velocity_z_device', 'gravity_x_world'}).

This happened while the csv dataset builder was generating data using

gzip://semidense_points.csv::hf://datasets/facebook/LAMP@9cdf546d39df180033f1b66d7f8bca23a78ed09b/test-library/semidense_points.csv.gz, ['hf://datasets/facebook/LAMP@9cdf546d39df180033f1b66d7f8bca23a78ed09b/test-library/closed_loop_trajectory.csv', 'hf://datasets/facebook/LAMP@9cdf546d39df180033f1b66d7f8bca23a78ed09b/test-library/semidense_points.csv.gz']

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)
