mmcv版本问题

[libingDY]

您好，mmcv已经升级到最新版本了，您代码中的mmcv_custom中的代码还是基于mmcv低版本写的，您能更新下代码吗？

[DotWang]

@libingDY 您好，当前这套代码是完完全全的老版本mmcv，mmdet，mmseg等，老版本上完全可以跑通。由于新老版本改动较大，我没有精力，也没有必要将老版本全部更新为新版本，建议您采用老版本来运行。据我所知，新版本可能已经支持mmcv_custom中的部分功能，您也可以找找看，这样可能就不需要mmcv_custom了。在之后的工作中，我们会采用全套新版本，谢谢关注！

感谢您的恢复，我用低版本的mmcv\mmdet进行了代码运行，但是我又遇到了以下问题：

您遇到过相似的问题吗？

[DotWang]

@libingDY 您好，我没有碰到过，你这是DDP方面的问题吧，我没有改OBBDetection，可能是你命令不对

[libingDY]

好的，非常感谢您的回复

[zhongyas]

您好，能提供您老版本的安装包版本吗？感谢

[DotWang]

@zhongyas 如果你说mmcv-full的话，安装的时候可以指定版本，我这里现在没有旧的了，如果你说的是obbdetection和mmsegmentation，完整框架在RSP仓库里，RVSA仓库只是提供相关的backbone和config等文件

[zhongyas]

十分感谢您的回复

[hhb442]

你好，我想问一下，这个backbone在初始化时候，使用的norm_cfg是SyncBN吗

[DotWang]

@hhb442 如果在多卡上finetune ViTAE-RVSA的话是，readme有写

[vxiaobai]

请问能否提供一下你的conda环境的压缩包呢，我想进行克隆以避免不用的版本错误

如果是单卡训练的话，应该是nn.SyncBatchNorm引起的，换成nn.BatchNorm2d就行了
