Something wrong with the model file?

[AnkushMalaker]

I get an unpickling error while following the steps on the README to setup the env, ie,

1. Create a .venv with python3 -m venv .venv. Source it.
2. Install current project with pip install .
3. Use specified command: reverb --model reverb_asr_v1 --audio_file audio.mp3 --result_dir results

  warnings.warn(

Do you have git lfs correctly setup before pip install .? I ran into the same error when downloading the asr model directly with git clone https://huggingface.co/Revai/reverb-asr and discovered that something wasn't right with git lfs. Instead of downloading the roughly 2Gb model, it downloaded a placeholder of some sort.

That was it, thanks!
Setup git lfs again and cloned manually, it works now.
