Hey! The error you're getting is because `.ix[]` was deprecated in **pandas** a while back and is no longer available in newer versions. That’s why you’re seeing the `'DataFrame' object has no attribute 'ix'` error.
ragdoll hitYou can fix it by using `.iloc[]` instead, which is meant for **positional indexing** (and looks like what you're doing here). Try replacing your line with:
```python
X = bank_full.iloc[:, [18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36]].values
```
This should work without any errors assuming `bank_full` is a valid DataFrame and the column indices exist. Let me know if you're still stuck!
