I am running a PyTorch code (2018 ish) with PyTorch 1.16 and I got the following error. Is there a quick fix for it?
landmarks_frame = pd.read_csv('faces/face_landmarks.csv')

n = 65 # Number of landmarks
img_name = landmarks_frame.iloc[n, 0]
landmarks = landmarks_frame.iloc[n, 1:].as_matrix()
landmarks = landmarks.astype('float').reshape(-1, 2)

print('Image name: {}'.format(img_name))
print('Landmarks shape: {}'.format(landmarks.shape))
print('First 4 Landmarks: {}'.format(landmarks[:4]))

the error is:
---------------------------------------------------------------------------
