A loading error in Win System.

[igo312]

my data has a name format like 'xxxx - xxxx.stem.m64'. but stempeg cannot reconginize the blank space before "-". So it will raise a error said there is no file.

The dataset actually is MUSDB18-7 set

I solve it by following codes which actually deletes the front blank space. But I hope there is a better way to solve it.

index = track_name.index('-')
track_name = track_name[:index-1] + track_name[index:]

Thanks for the report. Can you tell me which line triggers the error?

here's my tranceback. It is may not stempeg's fault, but I only trace it to this module.

Update: sorry for my poor thought about the problem. Right now, I don't think it's a name format problem. I delete all blank space and use os.path.exits() to check whether the file exists. And I get True from os.path.exits(). but same error infos from stempeg.Info()

>>>os.path.exists(r'F:\MUSDB18-7\AlJames-SchoolboyFacination.stem.mp4')
True

>>>stempeg.Info(r'F:\MUSDB18-7\AlJames-SchoolboyFacination.stem.mp4')

Ok. Can you check if you have ffprobe installed?

[igo312]

Well，it seems work by downloading ffmpeg.zip add them to env_path. Thank you @faroit !

Attention pip install ffprobe cannot solve problem

[faroit]

Great, that it works

Attention pip install ffprobe cannot solve problem

this is part of the ffmpeg installation. It cannot be installed with pip as pip only installs python software
