| Symptom | Cause | Fix |
|---|---|---|
| "CUDA out of memory" error | Insufficient VRAM for model | Use FP8/FP4 quantization or smaller model |
| "Invalid HF token" error | Missing or expired HuggingFace token | Set valid token: export HF_TOKEN=<YOUR_TOKEN> |
| Cannot access gated repo for URL | Certain HuggingFace models have restricted access | Regenerate your HuggingFace token; and request access to the gated model on your web browser |
| Model download timeouts | Network issues or rate limiting | Retry command or pre-download models |
NOTE
DGX Spark uses a Unified Memory Architecture (UMA), which enables dynamic memory sharing between the GPU and CPU. With many applications still updating to take advantage of UMA, you may encounter memory issues even when within the memory capacity of DGX Spark. If that happens, manually flush the buffer cache with:
sudo sh -c 'sync; echo 3 > /proc/sys/vm/drop_caches'
