coded with openai chart txt file to midi converter

Question

I have created this code in OpenAI to convert a music notes .txt file into a MIDI file, but it is giving me some errors. If anyone could provide kind assistance to fix it, I would be very grateful.

import mido

# Function to convert a music chart string into a MIDI track
def chart_to_track(chart, instrument):
    # Split the chart into a list of measures
    measures = chart.strip().split("|")
    # Initialize an empty list to store the MIDI events
    events = []
    # Set the current time to zero
    time = 0
    # Iterate through the measures
    for measure in measures:
        # Split the measure into a list of notes
        notes = measure.strip().split()
        # Iterate through the notes
        for note in notes:
            # Convert the note name to a MIDI pitch
            pitch = mido.note_to_midi(note)
            # Add a NOTE_ON event to the events list
            events.append(mido.Message('note_on', note=pitch, velocity=127, time=time))
            # Add a NOTE_OFF event to the events list after a quarter note duration
            events.append(mido.Message('note_off', note=pitch, velocity=127, time=480))
            # Increase the current time by a quarter note duration
            time += 480
    # Create a MIDI track with the events and the specified instrument
    track = mido.MidiTrack()
    track.extend(events)
    track.program = instrument
    return track

# Function to prompt the user to choose an instrument
def choose_instrument():
    # Print a list of instrument options
    print("Choose an instrument:")
    print("1. Acoustic Grand Piano")
    print("2. Electric Guitar (clean)")
    print("3. Violin")
    print("4. Trumpet")
    print("5. Clarinet")
    # Prompt the user to enter a number
    choice = input("Enter the number of your choice: ")
    # Return the corresponding instrument number
    if choice == "1":
        return 0
    elif choice == "2":
        return 25
    elif choice == "3":
        return 40
    elif choice == "4":
        return 57
    elif choice == "5":
        return 71
    else:
        print("Invalid choice. Please try again.")
        return choose_instrument()

# Main function
def main():
    # Prompt the user to enter the name of the text file
    filename = input("Enter the name of the text file: ")
    # Open the file and read the contents into a string
    with open(filename, "r") as f:
        chart = f.read()
    # Choose an instrument
    instrument = choose_instrument()
    # Convert the chart to a MIDI track
    track = chart_to_track(chart, instrument)
    # Create a MIDI file and add the track
    midi = mido.MidiFile()
    midi.tracks.append(track)
    # Prompt the user to enter the name of the MIDI file
    output_filename = input("Enter the name of the MIDI file: ")
    # Save the MIDI file
    midi.save(output_filename)

# Run the main function
main()

I tried to reinstall openai but not working i have tried in wsl2 ubuntu 22.04 lts & visual basic code windows 10`

**Outout of the Error **
Exception has occurred: AttributeError
module 'mido' has no attribute 'note_to_midi'
  File "D:\Astro\music.py", line 18, in chart_to_track
    pitch = mido.note_to_midi(note)
  File "D:\Astro\music.py", line 67, in main
    track = chart_to_track(chart, instrument)

The package librosa has a method note_to_midi(note) but mido does not. So install and import librosa and change pitch = mido.note_to_midi(note) to pitch = librosa.note_to_midi(note)

if you then give it a text file e.g. containing C♯3 B C D E C♯3 (note the spaces) it works.

See https://librosa.org/doc/main/generated/librosa.note_to_midi.html
