Jetson will not run?

When trying to run I get the following…
Traceback (most recent call last):
File “/home/john/Desktop/MyPython/”, line 24, in
import jetson.inference
File “/usr/lib/python3.6/dist-packages/jetson/inference/”, line 4, in
from jetson_inference_python import *
ImportError: cannot open shared object file: No such file or directory

What is wrong?
What shared object file?

I understand Python but not this…
