FileNotFoundError: [WinError 2] The system cannot find the file specified (using ffmpeg.probe())

Question

I'm trying to access metadata for a video using ffmpeg.probe() and it gives this error message. There is very little info on probe online.

import os
import ffmpeg


os.chdir('E:/F/Salvaged goods/Videos/Miro/Kvikmyndir/Blade_Runner_2049.1080p.WEB-DL.H264.AC3-EVO')

pprint(ffmpeg.probe(filename='Blade_Runner_2049.1080p.WEB-DL.H264.AC3-EVO.mkv', cmd='ffprobe'))

I have also tried this, and got the same error message:

pprint(ffmpeg.probe(filename='E:/F/Salvaged goods/Videos/Miro/Kvikmyndir/Blade_Runner_2049.1080p.WEB-DL.H264.AC3-EVO/Blade_Runner_2049.1080p.WEB-DL.H264.AC3-EVO.mkv', cmd='ffprobe'))

Here is the Traceback:
