Error: cudaMalloc failed: out of memory

Hello:

I use this code to detect bounding box in multiple images with GPU:

```
model = insightface.app.FaceAnalysis()
ctx_id = 0
model.prepare(ctx_id = ctx_id, nms=0.8)
faces = model.get(img)
for idx, face in enumerate(faces):
box=face.bbox.astype(np.int).flatten()
list_box.append(box)
```
When I process 500 images I get an error:

cudaMalloc failed: out of memory

How can I fix the problem?

Regards,
Roberto
