CUDA toolkit path

Locate the CUDA toolkit for workflows that require it. Do not point this setting at a Python environment or arbitrary executable.

Where to find it

Settings → Python

How to use it

Review the current value in Settings before changing it. New defaults do not overwrite values already saved on existing model features.

Result

Initial value: C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v13.3. Rebuild or rerun the affected operation when its inputs change.

Troubleshooting

Use Automatic or auto only where offered. Before increasing resource limits, check available memory and disk space; a larger limit does not improve numerical accuracy.
