Spleeter: [Discussion] download model archive on ecach process ?

[daslicht]

is it normal that spleeter lkeeps downloading the model archive on each process ?
I anytime get :
INFO:spleeter:Downloading model archive https://github.com/deezer/spleeter/releases/download/v1.4.0/2stems.tar.gz

Well, I have the same problem after trying to
pip install spleeter
and do
spleeter separate -i spleeter/audio_example.mp3 -p spleeter:2stems -o output
After checking the process:
I found

Does anyone know how long it takes for the model to download?

is it normal that spleeter lkeeps downloading the model archive on each process ?
I anytime get :
INFO:spleeter:Downloading model archive https://github.com/deezer/spleeter/releases/download/v1.4.0/2stems.tar.gz

Actually it is faster than I thought, around 6min with 300kb/s, better to have a process bar to
show the download procedure.

Hi @daslicht @Franceshe

It should definitely not need to download the model more than once. This probably means it gets saved in a temporary folder that is cleaned after your execution. What's your setup ? are you executing in a docker ?

[MrPatben8]

Is there a way to point spleeter to the folder of pretrained_models instead of having it download it and extract it every time?

[daslicht]

nope just macos mojave here. anyway to determine where it gets downloaded ?

[mmoussallam]

the model should be downloaded in a folder called pretrained_models by default.
You can change that (and actually avoid re-downloading) by explicitely setting the environment variable MODEL_PATH before calling spleeter.

[daslicht]

Ok, it seams to download that folder in the same folder execute the process. For any conversion I get an output and that pretrained_models folder. What is the best way to set the MODEL_PATH variable ?

[mmoussallam]

something like export MODEL_PATH=<path/to/pretrained_models/>

[daslicht]

and this will be permanent or just for the session ?

[mmoussallam]

Just for the session but you can also set it up permanently. Look on google how to depending on your OS and which terminal/shell you're using.

Got it, Thank you very much !
