Getting error trying to run code

[mreece813]

This is the error i am getting. I have found out that it is at
Line 76 : pc = pypcd.PointCloud.from_path(pcd_file)
I am not able to figure out why this is not working.
This is the errror:

I have also uncommented the lines for ring and intensity as well. Before when i used a file with out intensity and ring i was not getting any error but now i do. this is how the code looks now.
