iprec_at_recall trec_eval: duplicate cutoffs detected

[StamTheo28]

I am running an experinment in PyTerrier and i am trying to measure the iprec_at_recall at all recall values. However, i get the following error when i run the experinment ( works fine with other measures such as ndcg etc ).

trec_eval: duplicate cutoffs detected
python3: src/pytrec_eval.cpp:634: PyObject* RelevanceEvaluator_evaluate(RelevanceEvaluator*, PyObject*): Assertion 'te_trec_measures[measure_idx]->eval_index >=0' failed.
