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 2 new columns ({' x4', ' x3'})

This happened while the csv dataset builder was generating data using

hf://datasets/williamgilpin/dysts/coarse/ArnoldWeb_coarse.csv (at revision 5d305abb3c9010e36ca6a3e6c967b72932f6cca9)

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)

Chaotic Time Series Dataset

Multivariate time series from chaotic dynamical systems.

  • Each multivariate time series is a drawn from one chaotic dynamical system over an extended duration, making this dataset suitable for long-horizon forecasting tasks.

  • There are 4 million total multivariate observations, grouped into 135 systems and three granularities

  • The subdirectories coarse, medium, and fine each contain 135 .csv files, each of which contains a single multivariate time series of length 10,000

  • The number of channels varies depending on the specific dynamical system.

  • The time series are stationary due to the ergodic property of chaotic systems.
