Trying Run Python Code Importing Tnsorflow Installed Cpu Version Gpu Version Dd Go Well Li Q26132280

I have been trying to run a python code by importing TnsorFlow.I had installed a cpu version my GPU version dd not go through verywell

This is a linear regression code

When I tried to run it it gave me errors. I have attached thecode file as well as Error file

Can a expert help me in trouble shooting the error?
