fix: make TORCH_LOGS tutorial work without CUDA 7.0+#3910
Conversation
The tutorial had a guard that skipped all code when no CUDA device with compute capability >= 7.0 was available, causing the rendered docs to only show the skip message instead of actual logging output. Changed the guard to fall back to CPU tensors with the CPU inductor backend when no suitable GPU is found. This allows the tutorial to produce meaningful output regardless of the CI build environment. Fixes #137285
