AttributeError: 'super' object has no attribute 'init'

Question

I was making a personal assistant. I got an error in starting code:

import pyttsx3
engine = pyttsx3.init()
engine.say('How are you today?')
engine.runAndWait()

Error:

/usr/local/lib/python3.11/site-packages/pyttsx3/drivers/nsss.py:12: ObjCSuperWarning: Objective-C subclass uses super(), but super is not objc.super

During handling of the above exception, another exception occurred:

I don't know what is the problem. One more thing: due to some issue I had to uninstall old python version on Mac and installed new one using Homebrew.

Mac OS ventura 13.4

Python 3.11

Neptune

sorry, can't recreate , works okay for me(on mac Catalina, and pyttsx3 version 2.90), I think some dependency is missing for pyttsx3, try to reinstall pyttsx3 and look for warnings. – Copulative

I reinstalled it but no fix also their are no warnings while installing it. – Neptune

@Copulative check above – Neptune

created the virtual env and was able to recreate the problem. problem is with driver (nsss) [github.com/nateshmbhat/pyttsx3/blob/master/pyttsx3/drivers/… – Copulative

@Copulative same issue in venv – Neptune

Answer 1

this turns out to be a little tricky. and this is a workaround! hope works for you.

Under the hood, this module pyttsx3 uses PyObjC as a bridge between Python and Objective-C.

Step 1: Check that pyobjc is installed(pip show pyobjc), if not install as pip install pyobjc.
Step 2: open this file /usr/local/lib/python3.11/site-packages/pyttsx3/drivers/nsss.py and change the following:

#self = super(NSSpeechDriver, self).init() comment this line , and add the following
self = objc.super(NSSpeechDriver, self).init()

Note: from Foundation import * imports NSObject and objc from foundation, which has been consumed.

after the change, your following program would run okay.

import pyttsx3
engine = pyttsx3.init()
engine.say('How are you today?')
engine.runAndWait()

Answer 2

It seems that the supported Python versions are 3.5 to 3.7, as stated in the documentation. I can confirm that version 3.6.15 works fine with my Mac. (However, version 3.7.12 doesn't work.)

You may also need to add to your nsss.py file

import objc
