OSError: file not found

Description

Description

I face a problem when I follow the tutorial:

# Beat tracking example
from __future__ import print_function
import librosa

# 1. Get the file path to the included audio example
filename = librosa.util.example_audio_file()

# 2. Load the audio as a waveform `y`
#    Store the sampling rate as `sr`
y, sr = librosa.load(filename)

# 3. Run the default beat tracker
tempo, beat_frames = librosa.beat.beat_track(y=y, sr=sr)

print('Estimated tempo: {:.2f} beats per minute'.format(tempo))

# 4. Convert the frame indices of beat events into timestamps
beat_times = librosa.frames_to_time(beat_frames, sr=sr)

print('Saving output to beat_times.csv')
librosa.output.times_csv('beat_times.csv', beat_times)

Steps/Code to Reproduce

Expected Results

It may run without error

Actual Results

Are you sure that the file exists?

Hi, I am getting this same problem as well, a file not found error. I tried installing in a conda environment using conda install -c conda-forge librosa. I also made sure that ffmpeg is installed (4.3.1). Here’s the full message:
