Shared Object error while importing package

Question

I'm actually trying to import a package in the python shell but I get a shared object error

>>> from vosk import aligner
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/ec2-user/voice_recog/vosk-api/python/vosk/__init__.py", line 21, in <module>
    _c = open_dll()
  File "/home/ec2-user/voice_recog/vosk-api/python/vosk/__init__.py", line 15, in open_dll
    return _ffi.dlopen(os.path.join(dlldir, "libvosk.so"))
OSError: cannot load library '/home/ec2-user/voice_recog/vosk-api/python/vosk/libvosk.so': /home/ec2-user/voice_recog/vosk-api/python/vosk/libvosk.so: cannot open shared object file: No such file or directory

Also the init.py file has these lines

def open_dll():
    dlldir = os.path.abspath(os.path.dirname(__file__))
    if sys.platform == 'win32':
        # We want to load dependencies too
        os.environ["PATH"] = dlldir + os.pathsep + os.environ['PATH']
        if hasattr(os, 'add_dll_directory'):
            os.add_dll_directory(dlldir)
        return _ffi.dlopen(os.path.join(dlldir, "libvosk.dll"))
    elif sys.platform == 'linux':
        return _ffi.dlopen(os.path.join(dlldir, "libvosk.so"))
    elif sys.platform == 'darwin':
        return _ffi.dlopen(os.path.join(dlldir, "libvosk.dyld"))
    else:
        raise TypeError("Unsupported platform")

_c = open_dll()

This is the directory I'm working on root directory

And this is the directory of the vosk package

The link file depending upon the OS has to be downloaded from https://github.com/alphacep/vosk-api/releases and has to be placed in the respective directory where the error occurs.
