Python: Cannot import package VoigtFit in Jupyter Notebook

I am running Juptyer Notebook through Anaconda3 and I want to use functions from the package VoigtFit. I have already installed the package successfully, but when I try to import the package:

import VoigtFit

I get this error:

OSError: /static/Asplund2009.dat not found.

I was reading that OSError is a built-in exception in Python which is raised when an os specific system function returns a system-related error, including I/O failures such as “file not found” or “disk full”. I was wondering is it right to believe that I am supposed to download some file named Asplund.dat or if there is something else wrong here?
