How to read a ply file with only one intensity using pyhton

Question

I have a number of ply point clouds with only one intensity, i.e. [x y z intensity]. I plan to read them with open3d, but I can only read in the positions with the regular method. Is there a suitable way to do this with intensity?

path = './example.ply'
pcd = o3d.io.read_point_cloud(path,format='ply')

o3d.visualization.draw_geometries([pcd])
