I was setting up environments on my laptop with 1660 Ti, and I found out that 1660 Ti is no longer on the list.
CUDA GPUs - Compute Capability | NVIDIA Developer
Some old topics indicated 1660 Ti should support CUDA, did NVIDIA decided to ban us from do ML using 1660 Ti, 1660S, 1660, 1650S, 1650 recently? Because I can still remember that I ran some model back in June.
It still supports CUDA. There have been no changes in CUDA support on 1660 Ti
