"ModuleNotFoundError: No module named 'tkinter'" when trying to use matplotlib in Azure

I am attempting to use matplotlib on a Python script in Azure, using a WebJob on a Web App. I am getting the error below:

enter image description here

The error is obviously when importing tkinter, but based on this, it appears tkinter is not available in Azure. This is not a problem for me, as when I use it, I am just creating a PNG, so I believe I don't actually need it.

How can I get around this problem?

I solved this problem through this.

import matplotlib 
matplotlib.use('agg')
import matplotlib.pyplot as plt

According to the logs of your WebJob, you are using Azure WebApp for Windows to run it. Unfortunately, due to the Win32k.sys (User32/GDI32) Restrictions of Azure Web App sandbox, the job to create a PNG by matplotlib will never work for you, even after fix the current issue, because matplotlib requires GDI.

So I suggest that you can try to make the same Python script works on Linux and use crontab to trigger it, and to write a Dockerfile or build an Docker image for deployment on Azure WebApp for Linux. Please refer to the offical document Create a Python app in Azure App Service on Linux to get start.

You can't install tkinter with sudo apt-get install python-tk?

I usually have to install the package this way before it will work.
