RuntimeWarning: divide by zero encountered in true_divide

[Honghe]

Environment:

• Ubuntu 18.04
• Python 2.7/3.6
• TensorFlow 1.13
• keras 2.2

Before test, I truncated the voxceleb1_veri_test.txt to only 50 lines to speed up test.

Command:

python predict.py --gpu 0 --net resnet34s --ghost_cluster 2 --vlad_cluster 8 --loss softmax --resume ../model/gvlad_softmax/resnet34_vlad8_ghost2_bdim512_deploy/weights.h5

output:

Instructions for updating:
Colocations handled automatically by placer.
==> successfully loading model ../model/gvlad_softmax/resnet34_vlad8_ghost2_bdim512_deploy/weights.h5.
==> start testing.

[WeidiXie]

can you predict the whole list ?

[Honghe]

I haven't test all the whole list ;D

[WeidiXie]

I know, but please do that. Also, please read how EER/ROC is computed, then you will know why it's dividing by 0.
