ImportError: Unable to find zbar shared library

1

I have deployed a Python script in the free tier of render for hosting but the zbar library from pyzbar is giving me installation error/unable to find. As I mentioned in my requirement.txt file pyzbar==0.1.9 is available but it’s not importing the zbar from there. Can anyone please tell me how to sort this issue out for a successful deployment?

here is the error:
