'tuple' object has no attribute 'astype'

The error message you received suggests that you are trying to call the `astype()` method on a `tuple` object, which does not have an `astype()` method. The `astype()` method is a NumPy method that is used to convert the data type of an array.

It's possible that you have a tuple that contains numerical values, and you are trying to convert them to a different data type using `astype()`. To fix this, you should convert the tuple to a NumPy array first, and then use the `astype()` method. Here's an example:

import numpy as np

my_tuple = (1, 2, 3, 4, 5)
my_array = np.array(my_tuple)
new_array = my_array.astype(float)

In this example, we first convert `my_tuple` to a NumPy array using `np.array()`, and then we use the `astype()` method to convert the data type to `float`.
