I am using my own dataset and I have made the database as you said. However when I tried to extract features using extract_features.py, I got confused results.
I printed the features and found that the softmax layer gives the same number,
like
(Pdb) activations

since the number of labels I use is 90, the feature I get seems like an initialization. I am so confused. Could you give me some advice?
