Model Folder is empty

[muneebable]

Why the model folder is empty and where is model reside? I can't able to find it

[iamhankai]

I didn't put the pretrained model here. You need to train by yourself.

Also what is the technique, used for CUB attributes because there are 312 attributes but you processed attributes? What technique you used? I am trying to understand the meaning of this nb_attributes = [10, 16, 16, 16, 5, 16, 7, 16, 12, 16, 16, 15, 4, 16, 16, 16, 16, 6, 6, 15, 5, 5, 5, 16, 16, 16, 16, 5] like what is the meaning of 10 here[position represent bill shape etc]?

Also, I am getting this error, don't know why?

I am assuming the value of L is wrong because the for RESNET50, activation_49 have shape (?, 2048,7,7) but the while reshaping, you consider the value of L is 14*14.

The 312 attributes are clustered according to whether they are the same attribute.

The input image size is 448448, not 224224.

Thank you for you quick answers.

1. I am getting this error, I dont know what am i doing wrong I exactly run your code same.

The categorical_crossentropy loss in Keras may changed its API.

you can try to set from_logits=True in keras.backend.categorical_crossentropy(target, output, from_logits=False, axis=-1).

The prediction of network is a list of length 30 in which there are 28 attributes and what are the other two? I got the prediction on image, how can i see the attention on image?

[iamhankai]

The region_score_map in https://github.com/iamhankai/attribute-aware-attention/blob/master/cub_demo.py#L112 is the attention values. You can visualize it.
