The blanced entropy loss can't work

[exogeny]

I run the training code in r3d dataset, and can't get any room used the trained model.
The EVAL_pretrained file shows as follows:

Model at epoch 68: overall accuracy = 0.6127, mean_acc = 0.2182
epoch 68: 0th label: accuracy = 0.9814
epoch 68: 1th label: accuracy = 0.0
epoch 68: 2th label: accuracy = 0.0
epoch 68: 3th label: accuracy = 0.0
epoch 68: 4th label: accuracy = 0.0
epoch 68: 5th label: accuracy = 0.0
epoch 68: 6th label: accuracy = 0.0
epoch 68: 9th label: accuracy = 0.0
epoch 68: 10th label: accuracy = 0.9828

can you share any idea with the problem??

And also, i think the code of balanced entropy loss is different from the article.
