There’s a post entitled ‘Jupyter Notebook not detecting GPU’. What in steps that are covered in the troubleshooting suggestions there have you tried? What do you see when you run the code in the first post?
Minor:
Please read Getting good answers to your questions . In particular, the reference at the bottom How do I ask a good question? emphasizes don’t use screenshots, or at least not just screenshots, for things you could copy paste code with output as text. That allows the search indexing mechanisms to link things right and to make it easier for others following in your footsteps to find related content and troubleshoot easily. For example, note at the top of there, you can easily copy-paste the code and try it whereas by contrast a person finding this page cannot use your code easily. For pasting code into these posts, you’ll want it to show up formatted for those trying to help you, see about ‘block code formatting’ here. (Or see about ‘fenced code blocks’ here. They are both the same thing if you look into the details.)
