Error in debugging

i am facing problem in linking the datas from the self made library in python . The python shell shows a error that the contents of library doesnt exists.

Use the command “pip list” to see all the libraries installed locally. Search for your Self made library. If it doesn’t show, maybe you have not uploaded it. If it shows, make sure that the package is updated and the contents are not empty. Last resort is to create another library and try.
