[WinError 2]file not found error what is the problem?

from pydub import AudioSegment
import os

file_path = "your_music.mp3"
absolute_path = os.path.abspath(file_path)

audio = AudioSegment.from_file("your_music.mp3")

this code make a file not found error

  1. I installed os, pydub
  2. There is a file your_music.mp3
  3. I tried absolute_path.
  4. If I run “ls” code in python, the result show “your_music.mp3”

what is the problem???

  1. What folder is that file in?
  2. Why do you expect that Python will look in that folder for the file, and not any other folder?

Once you have considered these questions properly, if it was not a simple oversight, see here to understand how it actually works:

Exactly what code did you write to try this, and what happened when you tried it?

This makes no sense. ls isn’t Python code; it’s something you type at your computer’s command prompt.

Does absolute_path contain the correct path?

Hi thankyou for answer.

  1. C:\dev\music_proj is the path where file exist.
    2-1. I run git cmd, and move to "C:\dev\music_proj " this folder and run jupyter lab
    2-2. I make ipynb file at here.
    2-3. Because of the caused case, I run this code to check the directory where this python is.
    this is the code 2-3
import os

current_directory = os.getcwd()
print("directory:", current_directory)

2-4. To run absolute path I run the code below

from pydub import AudioSegment
import os

# run absolute path
file_path = "your_music.mp3"
absolute_path = os.path.abspath(file_path)
audio = AudioSegment.from_file("your_music.mp3")

Thank you. I will read the link which you linked.

Yes I think it’s correct.

this is my code to run absolute path

from pydub import AudioSegment
import os

# run absolute path
file_path = "your_music.mp3"
absolute_path = os.path.abspath(file_path)
audio = AudioSegment.from_file("your_music.mp3")

Can you copy paste the full error test including stack trace?

In my experience, a mysterious file not found error is often not about the file you think it is about. A fairly common source of errors is that something else is not found. In this case, pydub.AudioSegment uses ffmpeg.exe internally, so I’m slightly suspicious that maybe that executable is not found.


Okay, and what result do you get from the print call? Is it like you expect?

This won’t help, because os.path.abspath uses the same logic to decide how to create the absolute path.

  1. [code 1]
import os

# check directory
current_directory = os.getcwd()
print("directory:", current_directory)

directory: C:\dev\music_proj

Final error means = [WinError 2] Can’t find the file.

Okay, then @petersuter is right. If you didn’t already, you need to install the FFMpeg program (not a Python library, and nothing to do with Python) on your computer first. PyDub will work by launching that program as another process. If you already have FFMpeg installed, check the PyDub documentation to see how to make sure that it can find FFMpeg.

ffmpeg can be downloaded from here: Download FFmpeg
