Confusion in Using F5-TTS on Different Computers

[NickMC05]

I'm a newbie in this kind of stuff,
I have two computers
So I make this code to convert string into a wav file

`import subprocess
import sys
from pathlib import Path
from playsound import playsound

def main():
# 1) Get the text passed from Unreal (command line argument)
if len(sys.argv) < 2:
print("Error: No text provided. Usage: python run.py "Your text here"")
sys.exit(1)
user_text = sys.argv[1]

# 2) Locate the directory of this script:
script_dir = Path(__file__).resolve().parent

# 3) Walk up until you find the F5-TTS folder (not F5-TTS-main)
def find_tts_root(start: Path, marker: str = "F5-TTS") -> Path:
    for p in (start, *start.parents):
        candidate = p / marker
        if candidate.is_dir():
            return candidate
    raise FileNotFoundError(f"couldn't find '{marker}' above {start!r}")

tts_root = find_tts_root(script_dir)

# 4) Build the relative path to the .wav
ref_audio = (
    tts_root
    / "F5-TTS-main"  # Add this part here
    / "audio-references"
    / "basic_ref_en.wav"
)

# 5) Build command with dynamic text
command = [
    "f5-tts_infer-cli",
    "--model",    "F5TTS_v1_Base",
    "--ref_audio", str(ref_audio),
    "--gen_text",  user_text
]
print("command:")
print(command)
print()

# 6) Run it
try:
    result = subprocess.run(
        command,
        check=True,
        text=True,
        capture_output=True,
    )
    print("Command Output:", result.stdout)

    # Get the generated audio file path
    # The correct path is in F5-TTS/tests/ not F5-TTS/F5-TTS-main/tests/
    generated_audio = tts_root / "tests" / "infer_cli_basic.wav"
    
    # Verify the file exists
    if not generated_audio.exists():
        print(f"Error: Generated audio file not found at {generated_audio}")
        sys.exit(1)
        
    print(f"Playing generated audio from: {generated_audio}")
    
    # 7) Play the generated audio
    playsound(str(generated_audio))

except subprocess.CalledProcessError as e:
    print("ERROR:", e.stderr)
    sys.exit(1)

if name == "main":
main()`

What I do to convert string into a wav file is running this code:

python .\run.py "hello there"

It works on my first computer.
But on my second computer, I can't convert the string to a wav file:

`...F5-TTS> python .\run.py "hello there"
command:
['f5-tts_infer-cli', '--model', 'F5TTS_v1_Base', '--ref_audio', 'C:\Users\user\Documents\Unreal Projects\JobSimulator\F5-TTS\F5-TTS\F5-TTS-main\audio-references\basic_ref_en.wav', '--gen_text', 'hello there']

Traceback (most recent call last):
File "C:\Users\user\Documents\Unreal Projects\JobSimulator\F5-TTS\run.py", line 74, in
main()
File "C:\Users\user\Documents\Unreal Projects\JobSimulator\F5-TTS\run.py", line 47, in main

hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
FileNotFoundError: [WinError 2] The system cannot find the file specified`

What am I missing? How do I fix this to make it work like in my first computer?

Thanks

I have a few quick questions:

1. Have you created a virtual environment?
   If yes, could you activate your virtual environment (virtualenv or conda) and then run the following command?
   If you haven’t created one, you can run it directly:

where f5-tts_infer-cli

2. Have you installed the F5-TTS package on the second computer?
   (for example, using pip install f5-tts or pip install -e . inside the project folder)

3. Lastly, can you launch the f5-tts_infer-gradio interface and perform an inference successfully?
   If the Gradio interface runs without issues and produces audio, it means the model is installed correctly — the problem is most likely that the CLI tool isn’t available in your PATH.
