I need to save the tensor in a file after converting it into a list of arrays. I tried that

```
results = []
vec=model(preprocess(image).unsqueeze(0))
vec1=vec.numpy()
for ind in range(1):
results.append(vec1[ind])
return results
```

and got

RuntimeError: Can’t call numpy() on Tensor that requires grad. Use tensor.detach().numpy() instead.

then tried to convert this line `vec1=vec.numpy()`

to `vec1=vec.detach().cpu().numpy()`

but got `killed`

after some time
