How to infer song using only CPU?

[anywindo]

I don't have NVIDIA GPU so, i tweak the os environment to set visible cuda device to -1, it raised an error "Torch not compiled with cuda enabled". How can i do it using only CPU?

I solved that problem in part. There some code problems in module mdx.py. So, i edited these lines and now it can separate vocals and instrumental:

mdx.py:
...
169 mix_waves = torch.tensor(mix_waves, dtype=torch.float32)#.to(self.device)
...
194 processed_wav = self.model.istft(processed_spec)#.to(self.device))
...
245 #device_properties = torch.cuda.get_device_properties(device) if device.type == 'cuda' else torch.cpu.get_device_properties(device)
246 #vram_gb = device_properties.total_memory / 1024**3
247 m_threads = 1 #if vram_gb < 8 else 2

Perhaps, even can separate lead and back vocals and dereverb main vocal.
But i can't change the voice line in this moment. I hope i can fix this soon.

Edited:
I use console version without web ui.
