Fix DeviceLostError
in llama.cpp
✅ Solution
DeviceLostError in llama-cpp (Vulkan) usually indicates the GPU crashed or was reset, often due to exceeding available resources or a driver timeout (TDR). To resolve this, try reducing the batch size, sequence length, or model size to lower GPU memory consumption; alternatively, increase the TDR delay in your operating system settings if driver timeout is suspected. Also, ensure your GPU drivers are up-to-date for optimal stability.
