训练时Acc会一直为0吗？

[zch-ssc]

使用casia数据集训练，无预训模型。
使用config_ms1m_res50.yaml配置项acc会一直为0吗？

I use my the stanford dogs dataset to fine tuning , but get acc always 0 until 10000 steps. And the acc are nearly 1.0 or 0.99. What is the suitable config for new dataset?

I also encountered this problem, when fine tuning on my own datasets, the acc is always 0, did u solved this problem?

我也遇到了同样的问题，楼上的有解决方案了吗？

训练久一点，或者更换其他的参数试试。
