Hi @chenny2020 This behavior is usually symptomatic of trying to separate a too long signal on a computer with not much RAM. In this case, reducing the duration of the input signal using the -d option should solve the problem:

spleeter separate -i /root/2.mp3 -d 10 -p spleeter:2stems -o output

you'll then have to split your long signal in shorter chunks to separate it.
