This error occurs when you try to call the `tolist()` method on an integer object. The `tolist()` method is a numpy method that is used to convert an array to a Python list.
To fix this error, you need to make sure that the object you are calling the `tolist()` method on is actually a numpy array. If it is not a numpy array, you can convert it using the `numpy.array()` method before calling the `tolist()` method.
Here's an example:
``` python
import numpy as np
# create a numpy array
arr = np.array([1, 2, 3])
# convert the numpy array to a list
lst = arr.tolist()
# print the list
print(lst)
```
Output:
``` python
[1, 2, 3]
```
If you are still getting the error after ensuring that you are calling the `tolist()` method on a numpy array, you may need to check if there are any typos or syntax errors in your code.
