Fix NotImplementedError

✅ Solution

This error usually arises when a specific bitsandbytes feature, like double quantization or CPU/XPU support, is not yet implemented for your hardware setup (e.g., using ROCm on AMD GPUs) or the chosen device. To fix it, either switch to a supported configuration (like CUDA GPUs if applicable features are missing for ROCm), or wait for future bitsandbytes releases that might include the necessary implementation. Otherwise, remove the specific unsupported code from your implementation, opting for other quantization methods or supported devices.
