Just by executing this file so I can create an instance of it.
This is the only code above that in the file:
import os
import numpy as np
import pandas as pd
from skimage import io, transform
import matplotlib.pyplot as plt

import torch
import torch.utils.data as Dataset



# Face Landmarks Pose Estimation
# ------------------------------

def show_landmarks(image, landmarks):
    """Show image with landmarks"""
    plt.imshow(image)
    plt.scatter(landmarks[:, 0], landmarks[:, 1], s=10, marker='.', c='r')
