Fix DeviceLostError
in llama.cpp
✅ Solution
DeviceLostError usually indicates the Vulkan device (GPU) has been reset or become unavailable, often due to driver issues, overheating, or exceeding GPU memory limits. Try updating your GPU drivers to the latest version, reducing the model size or batch size to lower memory usage, or ensuring adequate cooling to prevent overheating. If the problem persists, investigate potential hardware issues, such as a failing GPU or insufficient power supply.
