Cx_Oracle issue

Hi everybody!

Good afternoon

I would like to know how to connect to Oracle Database, because I import cx_Oracle 7.2.2. in Pycharm 2019.2.1, and it give me a error like this:

First, this error: 

File "A:-------", line 4, in <module> import cx_Oracle as cx

Second, this error:

File"A:---\venv\lib\site-packages\cx_Oracle\__init__.py", line 10, in <module>
from custom_exceptions import Warning, Error, InterfaceError, DatabaseError, DataError, OperationalError, IntegrityError, InternalError, ProgrammingError, NotSupportedError
ModuleNotFoundError: No module named 'custom_exceptions'

I would like to know how I can fix it, 

Thanks

regards
