(the old) Google Colab by HV

(with OG demucs 2 ensembling for vocal models)

Add separate cell as following, or else it won’t work

!pip install torch=1.13.1 (probably numpy 1.25 for this old Torch)

 

If you're still getting errors, delete whole MDX_Colab folder, terminate your session, make clean installation afterward, and don't forget to have this torch line executed after mounting (that might happen in case you manually replaced model.py with some of the ones below, and didn't restore the correct old one).

 

(The Colab to use MDX easily in Google’s cloud. Newer models not included, and it gives error if you add other models manually - custom models.py necessary, only 9.7 [NET 1-3] and karaoke models included above)

 

(In case of “RuntimeError: Error opening 'separated/(trackname)/vocals.wav': System error.” simply retry)

 

More MDX models explained in UVR section in the beginning of the document since they're a part of UVR GUI now.

Optionally, 423 model can be downloaded separately here (just in case, it’s main). It is on MVSEP as well.
