# deprecated-type-alias (NPY001)
Autofix is always available.
## What it does
Checks for deprecated NumPy type aliases.
## Why is this bad?
NumPy's `np.int` has long been an alias of the builtin `int`. The same
goes for `np.float`, `np.bool`, and others. These aliases exist
primarily primarily for historic reasons, and have been a cause of
frequent confusion for newcomers.
These aliases were been deprecated in 1.20, and removed in 1.24.
## Examples
```python
import numpy as np
np.bool
```
Use instead:
```python
bool
```
