From the above error msg, I could see the attempt to import something from the path nougat/context/, however, in this Nougat package, there is no context directory at all. So I am very suspicious you're importing the wrong package. Based on this thread of thought, I found this package (https://github.com/Riparo/nougat), with the same name "Nougat". Likely, you're actually using this package behind the scenes, since I could see the usage of "cached_property" > here.

So my end solution is to do pip uninstall nougat and pip install nougat-ocr to specify the correct package.
