AttributeError: 'numpy.ndarray' object has no attribute 'convert'

This error message is indicating that you are trying to call the `convert()` method on a NumPy array, which does not have this method.

The `convert()` method is not a built-in method for NumPy arrays. If you are trying to convert the NumPy array to a different data type, you can use the `astype()` method instead. For example, to convert a NumPy array of integers to a NumPy array of floats, you could use:

import numpy as np

arr = np.array([1, 2, 3])
arr = arr.astype(float)

Alternatively, if you are trying to convert the NumPy array to a different data type that is not supported by the `astype()` method, you may need to use a different approach or function that is specific to the data type you are trying to convert to.
