Error running evaluation code

[katherine-atwell]

Hello, I have a slight error when it comes to running the evaluation code using the pretrained model on another corpus that I preprocessed. When I try to run the evaluation code, this is the message I get:
Load Brown clusters for creating features ... Load parsing models ... Load action classifier from file: ../data/model/model.action.gz with 110976 features and 4 actions. Load relation classifier from file: ../data/model/model.relation.gz with 35376 features at level 0, 17911 features at level 1, 16665 features at level 2, and 18 relations. Traceback (most recent call last): File "main.py", line 69, in <module> evaluator.eval_parser(path=args.eval_dir, report=True, bcvocab=brown_clusters, draw=False) File "/ihome/position-paper/StageDP2/src/eval/evaluation.py", line 64, in eval_parser met.eval(gold_rst, pred_rst) File "/ihome/position-paper/StageDP2/src/eval/metrics.py", line 42, in eval goldbrackets = goldtree.bracketing() File "/ihome/position-paper/StageDP2/src/models/tree.py", line 557, in bracketing relation = RstTree.extract_relation(node.relation) File "/ihome/position-paper/StageDP2/src/models/tree.py", line 501, in extract_relation return rel2class[s.lower()] KeyError: 'preparation'

Any help would be greatly appreciated!
