Convert heights and positions, which are regular lists, to numpy arrays. Call them np_heights and np_positions

Sure, here is how you can convert regular lists to numpy arrays in Python:

First, you need to import the numpy library. If you haven't installed it yet, you can do so using pip:

pip install numpy

Then, in your Python script, you can convert your lists to numpy arrays like this:

import numpy as np

# let's assume heights and positions are your lists
heights = [1.80, 1.85, 1.75, 1.90]
positions = ['GK', 'M', 'A', 'D']

# convert lists to numpy arrays
np_heights = np.array(heights)
np_positions = np.array(positions)

Now, np_heights and np_positions are numpy arrays.
