Model object has no attribute '_is_compiled'

I am working on a linux server with the adapt package version 0.4.4. If I run an example for the feature_based models  DANN, DeepCoral, WDGRL, CDAN, MCD, MDD, and CCSA I always get this error:

**AttributeError: 'DeepCORAL' object has no attribute '_is_compiled'. Did you mean: '_jit_compile'?**

Do you know how I can solve this? 

Thank you so much!
