loadUserData = ({x, yPred, yTrue}) => {
  if (isDatasetIncomplete({x, yPred, yTrue})) {

    return;

  return loadLocalData({
    fileList: [x, ...yPred, yTrue],

}
Convenient wrapper around `loadLocalData`, taking `x`, `yPred`, `yTrue` as input.
@param {Object} userData - {x: <file>, yPred: [<file>], yTrue: <file>}
