Dear, Jan.
Thank you for your kind and prompt reply.
I tried to make MWE as simple as it is. but it contains local PATH.
So, please check the line "sys.path.append('/home/jinsun/Dropbox/Yadee/Test')"
The script consist of 2 sequential script (c.py, c2.py)
You can find the follwoing error after running the final script (c2.py)
The operating system is UBUNTU 22.10
