Orbbec Python SDK

I am trying to start with Python SDK on my Persee+ which is running Ubuntu 18.04.

After setting everything up as the readme.txt says, I am trying to run one of the samples and I am getting this error:

ImportError: /home/orbbec/Desktop/sdk/python/linux/python3.8/Samples/Version.so: cannot open shared object file: No such file or directory

Did anyone face the same error?
