How can I resolve this ArrayFire error with Flashlight ASR?

[jksz1]

Question

I am trying to execute the following command to transcribe a .wav file using one of the pretrained models for Flashlight ASR:

/home/jonah/vcpkg/installed/x64-linux/tools/flashlight-cuda/fl_asr_test --am="/media/jonah/Linux Data/Flashlight-speech-recognition/am.bin" --lexicon="/media/jonah/Linux Data/Flashlight-speech-recognition/train_lexicon.txt" –datadir="/media/jonah/Linux Data/Flashlight-speech-recognition/" --test="/media/jonah/Linux Data/Flashlight-speech-recognition/test.lst" --tokens="/media/jonah/Linux Data/Flashlight-speech-recognition/tokens.txt" --emission_dir='' --nouselexicon –show

However, it gives an ArrayFire exception when executed:

terminate called after throwing an instance of 'af::exception'
what(): ArrayFire Exception (Internal error:998):

The format of the .lst file is as follows (with an empty transcription):

train001 /home/jonah/Downloads/sample.wav 51000

Does anyone know what is going wrong here? Any help would be appreciated.
