When submitting a question some background information is advisable. Please indicate OS and version, full Python version, SQLALchemy version, flask_sqlalchemy version. Also where is being run virtualenv, system, etc. Just noticed that visitors.py is in sqlalchemy package. Is that your module?user7070613– user70706132020-06-17 19:37:01 +00:00Commented Jun 17, 2020 at 19:37

I had this issue with SQLAlchemy 1.2.10. Upgrading to the current version (1.3.18 as of now) fixed the problem
pip install sqlalchemy --upgrade

The error occurs because in python 2, there is time.clock(), but in python 3, it has been replaced with time.perf_counter().
Just replace all the time.clock to time.perf_counter, and it should be fine. For more info: https://www.webucator.com/blog/2015/08/python-clocks-explained/

Except this is coming from the SQLAlchemy compat.py module. I'm not seeing
time_func = time.clock here: github.com/sqlalchemy/sqlalchemy/blob/master/lib/sqlalchemy/…. I suspect there is a version mismatch in either the Python or SQLAlchemy being used.I found a solution that worked for me I have a virtual environment carpet named env in which I installed sqlalchemy So, env\Lib\site-packages\flask_sqlalchemy_init_.py Inside that there is this code:
if sys.platform == 'win32':
_timer = time.clock
else:
_timer = time.time
And I changed clock to perf_counter() _timer = time.perf_counter()

Upgrading to the latest version solves the problem.
pip install flask_sqlalchemy --upgrade
