AttributeError: 'EncDecCTCModelBPE' object has no attribute '_wer'. Did you mean: 'wer'?

Hello, when I evaluate my ASR using this command, I get an error

python eval_beamsearch_ngram_ctc.py nemo_model_file=/home/user4/training/final_project/project6_nemo/models/python_model_conformer_ctc.nemo \               
             input_manifest=/home/user4/training/final_project/project6_nemo/data_manifest/dev_manifest4.json \
             kenlm_model_file=/home/user4/training/final_project/project6_nemo/LM/LM_models/old_LM_5gram \
             beam_width=[4,8,16,32,64] \
             beam_alpha=[-2.0,-1.0,0,1,2] \
             beam_beta=[-1.0,-0.5,0.0,0.5,1.0] \
             preds_output_folder=/home/user4/training/final_project/project6_nemo/LM/LM_models/pred \
             probs_cache_file=null \
             decoding_mode=beamsearch_ngram \
             decoding_strategy="flashlight"

The error is : _File "/home/user4/training/final_project/project6_nemo/LM/NeMo/eval_beamsearch_ngram_ctc.py", line 353, in main pred_text = asr_model._wer.decoding.ctc_decoder_predictions_tensor(preds_tensor)[0][0] File "/home/user4/.local/lib/python3.10/site-packages/torch/nn/modules/module.py", line 1695, in getattr raise AttributeError(f"'{type(self).name}' object has no attribute '{name}'") AttributeError: 'EncDecCTCModelBPE' object has no attribute 'wer'. Did you mean: 'wer'?

I tried to go to line 353 and change _wer to wer , ( I don't know if this was right), but after that It calculated WER and CER but I get this error: Beam search requires that consecutive ctc tokens are not folded

please tell me how to fix the problem, thank you

The same problem

Why do you think this error is in KenLM? The error occurs in NeMo/eval_beamsearch_ngram_ctc.py. So this sounds like it is in NeMo? Also EncDecCTCModelBPE is not from KenLM.
