Description

I tried deleting everything in my GDrive folder to start fresh and the issue still persists. It was working fine for me a week ago on an A100 session as well as L4, and now the output is feeding me Torch compatibility issues no matter what version or GPU I attempt.

Error below:

Research direction

Reproduce the reported Colab launch on the A100 or L4 runtime, then inspect launch.py and modules/launch_utils.py around prepare_environment(). Determine why the Torch/CUDA compatibility check now fails across the reported GPU and version attempts. Done means the cause and a verified corrective change or supported-runtime requirement are established without the RuntimeError.
