Example code throws java errors

On a fresh install, I get the exception JavaException: Provider for class javax.xml.parsers.DocumentBuilderFactory cannot be created when I run py-causal-continuous-example.py

I have the same issue. I have no clue where to update xerces... I cannot find a file with xerces in the name at all below the JAVA_HOME. (No Java expert here) Do I just download it from apache and put it in the lib of java?

EDIT: To answer my own question... Downloaded some JAR which looks like xerces from here And placed it next to the JARs of py-causal: /home/user/software/anaconda3/lib/python3.6/site-packages/pycausal/lib/ Seems to do the job...
