Lane Navigation System using Open-CV Python Raspberry Pi 4 & Tensorflow

I'm trying to run a model that I have trained on my raspberry pi using tensorflow but I couldn't run it due to errors as attached below. I have already installed the python3-tk package but it somehow failed to locate it. I am not sure whether it is due to my tensorflow version or my python version or something else. So basically I need help in troubleshooting the problem and help me run the program successfully.
