Thank you for your quick reply 
What i mean is I am trying to get every prediction from this throughout the testing and have at the end a list of
prediction : target

to be able to make an F-measure table from the results to have more information on the network’s answer quality.
I am also curious as to what the unnecessary indexing is, I have been working on many iterations of my code and I probably have left things I no longer need, I’d be happy to remove them.
Edit : I just thought that maybe having a testing batch of one would be a solution, wouldn’t it ?
