tkinter causes CustomObjectDetection module import failure in Google Cloud Function

Good afternoon,

I'm trying to upload a trained Custom Object Detection model to Google Cloud Storage and run inference using a Cloud Function. However, when I upload my function to the Google Cloud Platform, importing the CustomObjectDetection module fails. I think this is because one of the required packages is tkinter, which might not work in a cloud/headless platform? But I can't figure out why tkinter/a GUI would be required for imageai. Any help toward resolving this would be greatly appreciated! My code and the full stack trace of my error is below:

`import numpy as np from imageai.Detection.Custom import CustomObjectDetection

def predict(self): return "hello world"`

Deployment failure: Function failed on loading user code. This is likely due to a bug in the user code.
