AttributeError: 'OCEL' object has no attribute 'process_execution_mappings'

I tried to run your source code, but there was an error as follows:
Traceback (most recent call last):
File "D:\OCELFeatureExtractionExperiments-main\experiments.py", line 85, in
feature_storage = feature_extraction.apply(ocel, F, [])
File "D:\OCELFeatureExtractionExperiments-main\ocpa\algo\feature_extraction\factory.py", line 128, in apply
node.add_attribute(event_feature,VERSIONS[EVENT_BASED][event_function](node,ocel, params))
File "D:\OCELFeatureExtractionExperiments-main\ocpa\algo\feature_extraction\event_based_features\extraction_functions.py", line 164, in remaining_time
cases = ocel.process_execution_mappings[e_id]
AttributeError: 'OCEL' object has no attribute 'process_execution_mappings'
When I tried to correct this error, I found that there was still a problem with the subsequent execution. Does the source code need to be modified before it can be executed? I sincerely hope to get your reply.

Hi!
the complete code of these experiments (i.e. feature extraction) was integrated into the ocpa library (github.com/ocpm/ocpa). There is also the newest version of the code. Did you try using that instead of the local code provided here? Maybe that already solves the issue. (Right now, there are issues with dependencies with Python 3.10 so make sure to use Python 3.9).
Best
