I have some question about the version of detectron2 hydra-core and omegaconf

[lyzhenshuai]

Hello Author！ When I can't get git using the URL you provided,so I used the latest version of detectron2,it need hydra-core>=1.1 and omegaconf>=2.1. I upgraded two dependent versions--------hydra-core 1.2.0 and omegaconf 2.2.3 I encountered the following problem：

I want to know which the version of detectron2 hydra-core and omegaconf should be installed or 'config.backbone' and 'config.model' can be ''hydra.utils.instantiate'' called ?

Thank you！！！

@lyzhenshuai Hi! I met the same problem. Have you solved it?

[Wenhua98]

Hi！I also met the same problem.Have you solved it?

[lyzhenshuai]

Hi！I also met the same problem.Have you solved it?

When installing detectron2, do not install the dependent library, and then install the old version of hydra-core and omegaconf through pip. Although there are many warnings, it can run

I and my friends met the same problem, and we have no ways to solve it.

Thank you for your reply. I also found out that it is enough to install hydra, omegaconf and pytorch-lightning versions on the side of the installation.

Hi!

I can confirm. I did it the same way like @lyzhenshuai and @Wenhua98 . Pip complains about this, however, this ensures that the right versions are installed.

Best, Jonas

Hi! I do not understand how to install detectron2 but do not install the dependent library, how to implement this, please? And what version does it mean for old version of hydra-core, please? I tried version hydra-core 1.0.7 & omegaconf 2.0.6 (cannot import name 'SCMode' from 'omegaconf') and hydra-core 1.0.7 & omegaconf 2.3.0 (cannot import name 'get_ref_type' from 'omegaconf._utils' ) but none can be run. So do you know how to fix this problem, please?

I met the same problem. hydra-core 1.0.5 & omegaconf 2.0.6 (cannot import name 'SCMode' from 'omegaconf')

So do you know how to fix this problem, please?

for example 'pip install omegaconf==2.0.6 hydra-core==1.0.5 --no-deps',Where {--no-deps} means no dependencies are installed，About (cannot import name 'SCMode' from 'omegaconf') the question, i don't meet it ,You can check whether your version contains this function

嗨！我也遇到了同样的问题。你解决了吗？

安装 detectron2 时，不要安装依赖库，然后通过 pip 安装旧版本的 hydra-core 和 omegaconf。尽管有很多警告，但它可以运行

Hi ! I'm new to GitHub, what's your pip command line, can you tell me?

change to: self.backbone =config.backbone
