Trouble running pyttsx3 text to speech converter

I’m trying to build a voice assistant and I’m using nuitka for speed improvement.

0.6.12.3
Python: 3.7.3 (default, Jul 25 2020, 13:03:44) 
Executable: /usr/bin/python3
OS: Linux
Arch: armv7l

Here is my code:

from fuzzywuzzy import fuzz
import sys
import pyttsx3
engine = pyttsx3.init()
text = "Hairy activated"
voices = engine.getProperty("voices")
print(voices)
engine.setProperty("rate", 135)
engine.setProperty("voice", voices[10].id)
engine.say(text)
# play the speech
engine.runAndWait()
from os import environ, path
import os
#sys.path.insert(0, '/home/pi/AIY-voice-kit-python/src/examples/voice')
#from __init__ import LiveSpeech, get_model_path
from pocketsphinx import LiveSpeech, get_model_path
model_path = get_model_path()
print("active")
speech = LiveSpeech(
    verbose=False,
    sampling_rate=16000,
    buffer_size=2048,
    no_search=False,
    full_utt=False,
    hmm=os.path.join(model_path, 'en-us'),
    lm=os.path.join(model_path, 'en-us.lm.bin'),
    dic=os.path.join(model_path, 'cmudict-en-us.dict')
)

for phrase in speech:
    p = str(phrase)
    print(p)
    r1 = (fuzz.ratio(p,"harry"))
    print(r1)
    ri = int(r1)
    if ri > 59:
        text = "Yes?"
        engine.say(text)

here is the command:

python3 -m nuitka --run --follow-imports /home/pi/Desktop/AIY-projects-python/src/examples/voice/speack.py

and here is the log:

Is there any more information you want? Please help as soon as you can.

This is not standalone mode, so it wouldn’t have to follow it for compilation, however, there are issues when things are mixed, compiled or not, then the loader of Python can’t load the compiled stuff, and vice versa, so far it only loads extension modules, but not sourcefiles or bytecode. This is a missing feature indeed.

The extension modules were most pressing, but this surely is annoying too. You can fix this potentially with provisions of --include-package on the trouble makers, so no mixing occurs, unless of course it’s not found at compile time.

Thank you @kayhayen --include-package=src.modules for me worked.
