Flashlight decoder for ASR
Yes it's supported, please find installation instructions here - https://docs.nvidia.com/nemo-framework/user-guide/latest/nemotoolkit/asr/asr_language_modeling.html#n-gram-language-modeling

That bash script has to be run by users as is, rather than python to install flashlight  I followed this guide but it refers to scrips that don't exist anymore. For example the following script is not relevant already:
```
python eval_beamsearch_ngram.py nemo_model_file=<path to the .nemo file of the model> \
       input_manifest=<path to the evaluation JSON manifest file \
       kenlm_model_file=<path to the binary KenLM model> \
       beam_width=[<list of the beam widths, separated with commas>] \
       beam_alpha=[<list of the beam alphas, separated with commas>] \
       beam_beta=[<list of the beam betas, separated with commas>] \
       preds_output_folder=<optional folder to store the predictions> \
       probs_cache_file=null \
       decoding_mode=beamsearch_ngram \
       decoding_strategy="<Beam library such as beam, pyctcdecode or flashlight>"
```
because there is no eval_breamsearch_ngram.py [here](https://github.com/NVIDIA/NeMo/blob/stable/scripts/asr_language_modeling/ngram_lm/eval_beamsearch_ngram.py). @karpnv could you update docs ? NeMo of previous versions has it but there are no such parameters as `decoding_strategy`. I mean it can't be used as flashlight. And even in older versions of NeMo it's absent. For example in [1.18.0](https://github.com/NVIDIA/NeMo/blob/v1.18.0/scripts/asr_language_modeling/ngram_lm/eval_beamsearch_ngram.py) This issue is stale because it has been open for 30 days with no activity. Remove stale label or comment or this will be closed in 7 days. This issue was closed because it has been inactive for 7 days since being marked as stale.
[At this page](https://docs.nvidia.com/nemo-framework/user-guide/latest/nemotoolkit/asr/asr_language_modeling.html#flashlight-flashlight) you describe how to use flashlight decoder by launching your python script. But I can't find any parameters it should have. In further NeMo versions you have [installation guide](https://github.com/NVIDIA/NeMo/blob/2331b063d6f0282fa79c32e4e780db6cc7ef19f2/scripts/asr_language_modeling/ngram_lm/install_beamsearch_decoders.sh#L53) but no python script to use it.

Can you please help me with that? This feature (flashlight decoder) is still in progress or deprecated?
