Sorry, I missed it.

Could you tell me where you get decode_with_HLG.py?

This mode https://huggingface.co/csukuangfj/icefall-asr-librispeech-conformer-ctc-jit-bpe-500-2021-11-09/tree/main
is from
https://github.com/k2-fsa/icefall/tree/master/egs/aishell/ASR/conformer_ctc
and there is no decode_with_HLG.py inside the directory conformer_ctc.

If you write decode_with_HLG.py yourself, would you mind sharing it with us?

I got decode_with_HLG.py from links you have provided in Readme : https://github.com/k2-fsa/icefall/blob/master/egs/librispeech/ASR/conformer_ctc/jit_pretrained_decode_with_HLG.py
This is the file i have used:
decode_with_HLG.zip

This is the procedure I have followed: first, i have converted HLG.pt to HLG.fst by running
python3 convert-k2-to-openfst.py --olabels aux_labels ./lang_bpe_500/HLG.pt ./lang_bpe_500/HLG.fst

Please generate HLG.fst with the following script
