How to Clear GPU VRAM Without Rebooting (Linux & Windows)

For Data Scientists and DevOps engineers, an Out-of-Memory (OOM) error on a GPU is a daily frustration. But what happens when the VRAM stays fully allocated after your training script has ended?
Rebooting an entire production server disrupts other users and breaks active SSH sessions. Instead, you can release stuck VRAM directly from the command line.
Our engineering team just published a tactical guide on clearing GPU memory without a system restart. We cover:
🔹 How to identify ghost processes holding VRAM using nvidia-smi.
🔹 Why memory fragmentation inside Python frameworks looks like a leak (and how to clear it using garbage collection).
🔹 How to execute a hardware-level GPU reset (--gpu-reset) or force a PCIe bus rescan on Linux.
🔹 The Windows shortcut (Ctrl + Shift + Win + B) to instantly restart the display driver.
