Invalid permutation error reading image feature you gave

[Gi-Cheon Kang]

Hi, I just want to run the pretrained model but error occurs reading image features
(Invalid permutation error).

I downloaded preprocessed data below.

preprocessed data (data/)
visdial_data_trainval.h5, visdial_params_trainval.json, data_img_vgg16_relu7_trainval.h5

pretrained model (checkpoints/)
lf-att-ques-im-hist-disc-vgg16-24.t7

I run the command below (test set)
th evaluate.lua -loadPath checkpoints/lf-att-ques-im-hist-disc-vgg16-24.t7 -gpuid 0 -split test

lf-att uses pool5 features, not relu7 features. pool5 features are available here as well: https://github.com/batra-mlp-lab/visdial#v10.

Alternatively, you should be able to evaluate any non-attention-based model checkpoint with these data files.

@abhshkdz oh, thank you very much.
