Hi! I think that, in my cursory reading, I misunderstood what the code is doing. I thought it was importing the module you're trying to analyze... I'll have to read more closely when I have some spare time.
Makes sense! I think the commenter below correctly addressed the true security concern here which is importing arbitrary python libraries. As is, import_tracker doesn't attempt to solve this problem (though it's an interesting one to consider for this or a similar library). Please feel free to reach out with any other questions if you're curious.
