How do I solve a KeyError when importing a python module?

问题

I was trying to import a module from a different directory level so I used:

    import os
    import sys
    sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), '..')))

But now I get this error. I'm using Spyder and the first time I use the following import, it works fine.

   from source.search.ci_search_project import CI_Search_Project

From the second time I get this error.

File "ipython-input-29-f35dfe634c32", line 1, in module runfile('C:/Users/nrshakya/Documents/CI/src/Comp_IntelPython/ci_search_project_test.py', wdir='C:/Users/nrshakya/Documents/CI/src/Comp_IntelPython')
