Hi,

I am having a problem now, I am running my code on google colab with 12 GB Ram, I have images stored at numpy files and I want to transfer them to tensors, but the ram is crashing.

This is my code:

```
X_train, X_val, y_train, y_val = train_test_split(X,y, test_size = 0.10, random_state = 87, stratify = y)
X_train = torch.from_numpy(X_train).float().cuda() # transform to torch tensor
y_train = torch.from_numpy(y_train).float().cuda()
X_val = torch.from_numpy(X_val).float().cuda()
y_val = torch.from_numpy(y_val).float().cuda()
```
