DOCPLEX does not work - CPLEX runtime not found

I am facing an error like below, while I have installed docplex module and am using python 3.7/3.8. Would you please help me?

Traceback (most recent call last):
  File "C:/Users/xxx/PycharmProjects/pythonProject/EPC _LTC.py", line 155, in <module>
    solution = mdl.solve(log_output=True)
  File "C:\Users\xxx\PycharmProjects\pythonProject\venv\lib\site-packages\docplex\mp\model.py", line 4222, in solve
    return self.fatal("CPLEX runtime not found: please install CPLEX or solve this model on DOcplexcloud")
  File "C:\Users\xxx\PycharmProjects\pythonProject\venv\lib\site-packages\docplex\mp\model.py", line 894, in fatal
    self._error_handler.fatal(msg, args)
  File "C:\Users\xxx\PycharmProjects\pythonProject\venv\lib\site-packages\docplex\mp\error_handler.py", line 210, in fatal

docplex is only the modeling layer - you need to install CPLEX separately. If you can use the community edition, you can just pip install cplex in your python environment. If you are using a commercial edition, you need to install the CPLEX python api as instructed here: https://www.ibm.com/docs/en/icos/20.1.0?topic=cplex-setting-up-python-api
