Error importing "IfxPy" ##ImportError: libthcli.so: cannot open shared object file: No such file or directory

[unikill066]

I am getting an error while I try to connect to Informix DB from the Linux system, please check and suggest me appropriate fixes.

(venv) [user@server connector_testing]$ python3 informix_connector.py
Traceback (most recent call last):
  File "informix_connector.py", line 1, in <module>
    import IfxPy
ImportError: libthcli.so: cannot open shared object file: No such file or directory
(venv) [user@server connector_testing]$ cat informix_connector.py

informix_connector.py:

import IfxPy

ConStr = "SERVER=ol_informix1410;DATABASE=sysmaster;HOST=host;SERVICE=port;UID=informix;PWD=password;"
conn=IfxPy.connect(ConStr,"","")

Thanks
