tkinter causes CustomObjectDetection module import failure in Google Cloud Function

[LOActualControl]

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. Error message: Traceback (most recent call last):

Good afternoon,

I'm also getting the same issue but with Azure cloud platform. However, I'm not sure why we need tkinter because of the following:

It seems like he is defining Image in line 2 but later he redefines Image in line 5 , so this leads me to believe that perhaps we do not need tkinter?
Thoughts ?

Yeah I noticed the same thing too @EdwinAguirre92 ! In fact, I assume the rest of the Image references in the functions/classes that follow are from the PIL import, rather than the tkinter import. Perhaps tkinter isn't necessary after all - I ended up actually using a different package than ImageAI for my current project, but removing tkinter could be helpful for future projects.
