text: Title: Warning in EDA
  Body: During the analysis of `robert` dataset from OpenML:
  
  ```py
  Using a non-tuple sequence for multidimensional indexing is deprecated; use `arr[tuple(seq)]` instead of `arr[seq]`. In the future this will be interpreted as an array index, `arr[np.array(seq)]`, which will result either in an error or a different result.
  ```
