Hi all,
Suppose I extracted the image features from a pretrained CNN and wants to save these features to disk for later use. Which of the following will be a good method in terms of memory and speed.

Store the feature dictionary in a pickle file
Convert the feature tensor to numpy arrays and save using np.save()
Save it in a json file ( TypeError: Object of type ‘FloatTensor’ is not JSON serializable is coming)

Thanks!!
