'Series' object has no attribute 'to_numpy'

The error message you mentioned typically occurs when you try to call the `to_numpy()` method on a Pandas Series object that doesn't support this method.

The `to_numpy()` method is available in Pandas version 0.24 and above. If you are using an older version of Pandas, this method might not be available.

To resolve this issue, you can either upgrade your Pandas version to 0.24 or above or use alternative methods to convert your Series object to a NumPy array. One such alternative is using the `values` attribute of the Series object, like this: `series.values`. This will return a NumPy array containing the values of the Series.

Here's an example:

import pandas as pd

# Create a Pandas Series
series = pd.Series([1, 2, 3, 4, 5])

# Convert the Series to a NumPy array
numpy_array = series.values

print(numpy_array)

This will give you the NumPy array representation of your Series object.
