KeyError when Test

[cgy-01]

When I follow the steps to configure the environment and run Test, I get the error “KeyError: 'BAN_MLPDecoder is already registered in model at opencd.models.decode_heads.ban_utils'”, how do I fix it?

try this version of opencd

Please provide full error reporting information, or just use open-cd, which now supports BAN.

作者你好，我遇到了同样的问题，以下是完整报错信息：
Traceback (most recent call last):

另外，我尝试了在test.py中直接import opencd，会有以下报错：

使用这个版本的open-cd作为依赖：https://github.com/likyoo/open-cd/tree/f05e7fdfe1e0f9a9afa9d6c063ea03b43345226e

或者直接使用最新版的open-cd

感谢，已通过直接使用open-cd中的BAN解决
