您好，目前并没有遇到这种情况，或者您方便说一下您的设置吗？您方便将带有ECAM的实验重复一下吗？

是否是加载和预处理数据时有问题呢，可以检查一下

Could you provide the config file in your work_dir? And [this](https://github.com/open-mmlab/mmengine/blob/main/mmengine/visualization/visualizer.py#L864) may be helpful for you.

 Try: ``` palette=[[0, 0, 0], [255, 255, 255]] ```

emmm.. I think the palette is just for visualization. plz make sure all bands are loaded. Check [here](https://github.com/likyoo/open-cd/blob/main/opencd/models/backbones/tinynet.py#L415), [here](https://github.com/likyoo/open-cd/blob/main/configs/_base_/models/tinycd_v2.py#L5), [here](https://github.com/likyoo/open-cd/blob/main/configs/_base_/models/tinycd_v2.py#L7), and so on.

Thanks for your attention, you can refer [here](https://github.com/likyoo/open-cd/blob/main/configs/stanet/stanet_base_256x256_40k_levircd.py#L8).

test pipeline中参数写为`1024`是因为原图大小为1024，即未对尺寸进行进一步处理。
