Spleeter: [Bug] Why can't python find any file?

[omgwtfbbqpls]

I'm trying to run this script in the command prompt with my python installation. No matter how I try and type the file path it can't find any file. I used backward slashes, tried replacing the spaces with underscores, didn't work.
So I decided not to include any filepath and just type "test.mp3" and put the file in the System32 folder (where the command is being run?), but it can't find the file either (example below).
Then I decided to run it in another directory (C:) and move the file there, but the stupid thing just started downloading another copy of the model. And failed to find the file. Again.

OS - Windows 7
Installation type - Uhhh, pip?
RAM available - In total? 8 GB
Hardware spec - GTX 1050 Ti

Are there any plans for a GUI? I really really really hate terminal commands because of garbage like this.

Really looking forward to a response on how to write the filepath, as this program looks amazing. Cheers.

You need to install ffmpeg and add it to your PATH variable. That fixed it for me

Filenames with spaces should be in quotes for example "First Test.mp3". With the Output path I cannot Help you though sry
