[peerjuettner]

Getting segmentaiton fault on my docker machine. It has low RAM, 2GB, and i'm wondering if this is supported? I didnt find anything in the docs.

Hi @peerjuettner

It may be link to #229. In any case 2Gb is probably too low to have spleeter process complete audio files.

Thanks for the reply. As the processing speed doesn't really matter to me, I will try upping the swap space. I'll report if this helps.
Edit: Sometimes, the application also gets killed with this message:

i have read that someone have execute spleeter with good result in a 4gb machine with 2stems, 4 and 5 stems are for more than 8gb ( i have to buy more ddr ;o) )

Hi everyone.

We will soon release a new version (1.5) with a small change allowing to use librosa implementation of the STFT instead of the tensorflow one that appears to be very memory consuming. The PR is #282 so feel free to test it and/or join the conversation there.

Hi @peerjuettner

We've released spleeter 1.5, could you check if this new version solves your problem ?

With some 10 minutes songs I have OOMKill even I have 16GB of RAM ;)
@mmoussallam I'll check the latest version!

[peerjuettner]

@mmoussallam is this already on conda? It keeps downloading model 1.4 for me.

[mmoussallam]

Hi @peerjuettner,

We seem to have an issue with the conda package on windows, so we're stuck on 1.4. We're looking into it.

[peerjuettner]

@mmoussallam Thanks for the heads up. Could I build from source and try again or is there another way to test the newest release? I'm eager to try it.

[mmoussallam]

Hi @peerjuettner

the issus was solved and you should probably have no issue anymore.
