Low performance when i train about image_segmentation

[summerflowernb]

It should be possible to modify the 'length' variable in the solver.py file, and its accumulation should be length=length+1

Thanks for sharing useful project I have a question about the score in this repo I had prepared the data ISIC same yours.

1815 images were used for training, 259 for validation and 520 for testing models

When I train your model with the data ISIC, the result is very bad.

@LeeJunHyun can you solve this for me. Thanks.

Hello, I have the same problem. Have you solved it before?

感谢分享有用的项目我有一个关于这个 repo 中的分数的问题，我准备了与你相同的数据 ISIC。

1815 张图像用于训练，259 张用于验证，520 张用于测试模型

当我使用数据 ISIC 训练您的模型时，结果非常糟糕。

@LeeJunHyun你能帮我解决这个问题吗？谢谢。

你好，我也有同样的问题。你以前解决过吗？

Please have you solved this problem?

It should be possible to modify the 'length' variable in the solver.py file, and its accumulation should be length=length+1

Is it because it is stacked once each time, so each time +1 and then averaged?
