'float' object has no attribute 'astype'

This error message typically occurs when you try to use the `.astype()` method on a `float` object.
The `.astype()` method is used to convert the data type of a NumPy array, but it is not a method that is available for Python built-in data types like `float`.
To fix this error, you may need to convert the `float` object to a NumPy array first, and then use the `.astype()` method on the array.
For example:
```
import numpy as np
my_float = 3.14
my_array = np.array([my_float])
my_array = my_array.astype(int)
```
In this example, we first create a `float` object called `my_float`. We then convert it to a NumPy array using `np.array()`, and finally we use the `.astype()` method to convert the data type of the array to `int`.
