Process Request API

Hello,
I have downloaded the SentinelHub project from GitHub. I am using the process_request.ipynb file to run the project to test, as shown in a video. But, it gives errors mentioning no module name ‘sentinelhub’ .
I have tried changing the relative importing references, but it is not working…
Do you have any tips/advice to set up the project and run the process_request from the examples folder?
Thank you
