Java pacakge edu is missing for domain knowledge file

[TangChenTom]

Hi, I am using the example code to import PC from pyrca.graphs.casual.pc to use my domain knowledge file. However, there is an error saying a Java package 'edu' is missing:

Traceback (most recent call last):
File "/home/tom/latency_analysis/analysis.py", line 10, in

raise ImportError("Java package '%s' not found, requested by alias '%s'" % (jname, name))
ImportError: Java package 'edu' not found, requested by alias 'edu'

My environment is Ubuntu 22.04 with openjdk 21.0.4. I install pyrca via the source code and the command pip install . I also installed all dependencies by pip install .[all]. Can you please check?

Same here, have you solve it yet?

Yes. It appears that in order to proceed with the intended course of action, it is imperative to procure the missing package externally and subsequently ensure its proper placement within the designated directory hierarchy, as this is a critical prerequisite for the successful execution of the program and the attainment of the desired outcome.
