4. Troubleshooting

4.1 Cache off

isaac sim 右上角 cache显示 cache off

local nucleus cache 报错: cannot connect to system monitor backend

此时 cache选择的是最新版本 2023.2.3, 建议更改较低的版本试试，目前选择 2023.1.1

4.2 Failed to solve some dependencies locally...

安装omnigibson时包含以下报错：

Failed to solve some dependencies locally...

ModuleNotFoundError: No module named 'omni.kit.usd'

'trusted' is not set for registry 'kit/default' in '/exts/omni.kit.registry.nucleus/registries' 

[omni.kit.app.plugin] Exiting app because of dependency solver failure...

原因是isaac sim版本不适配，最新的4.0.0不包含omni.kit.streamsdk.plugins' = { version='=2.5.2' }

建议切换至2023.1.1：在exchange搜索isaac sim之后从最右侧的入口下载历史版本。最左侧只有最新版4.0.0

4.3 Isaac Sim Compatibility Checker 报错

Failed to solve some dependencies locally...

目前貌似不影响正常使用
