(UPDATED) psycopg2 [Import Error] on Windows - ImportError: dynamic module does not define module export function (PyInit__psycopg)

[UPDATE] - An antivirus software installed on my computer was causing the issue. Disabling it solved the problem :)
I'm getting a weird error when I try to import psycopg2.
Using Python 3.7.7
Downloaded psycopg2 using pip
$ python -m pip install psycopg2
Collecting psycopg2
Using cached psycopg2-2.8.5-cp37-cp37m-win_amd64.whl (1.1 MB)
Installing collected packages: psycopg2
Successfully installed psycopg2-2.8.5
import psycopg2
if name =="main":
print("Hello World!")
Running the code gives me the below error:
$ python test2.py Traceback (most recent call last): File "test2.py", line 1, in <module>
import psycopg2
File "C:\Users\blah\AppData\Local\Programs\Python\Python37\lib\site-packages\psycopg2\__init__.py", line 51, in <module>
from psycopg2._psycopg import ( # noqa ImportError: dynamic module does not define module export function (PyInit__psycopg)
Have tried installing pscopg2-binary instead. Still getting the same error.
Any idea?

I am unable to import psycopg2 from Jupyter notebook or Jupyter Lab on Mac. I have a clean install of Catalina

A similar report was posted, but the suggested solutions do not work.
---- from Jupyter ----
Import psycopg2
ModuleNotFoundError Traceback (most recent call last)
<ipython-input-2-7d2da0a5d979> in <module>
----> 1 import psycopg2
ModuleNotFoundError: No module named 'psycopg2'
If I run python3 from Mac terminal and then import psycopg2 that works.
If I run python3 from Jupyterlab terminal this does not work. I get the following error after running import pyscopg2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

These look the same, just in a different order.
I have tried pip install psycopg2 both with and without the binary option.Either way, it says already satisfied.
I have tried
conda install -c anaconda psycopg2
Also tried installing postgresql both from the postgresql.org, and brew install psycopg2. Both worked, but no luck with Jupyterlab.

try installing the package using: pip install psycopg2-binary. This should work.

Cannot import zmq in python using pycharm

I am trying to use the zmq Python library but it is not recognized and I have already installed it by using the following command:
pip3 install pyzmq
I am using PyCharm IDE.
The run output gives me this error:
Traceback (most recent call last):
File "C:/Users/Operações/Desktop/Testes/teste.py", line 2, in <module>
import zmq
ModuleNotFoundError: No module named 'zmq'
Does anyone can help me with this?

Instead of using pip, try installing pyzmq from File/Settings in PyCharm.
Open the Settings/Preferences
Navigate to Project: -> Python Interpreter
Klick the + at the bottom of the list
Search for your package of choice and hit Install Package

ModuleNotFoundError: No module named 'PyMySQL'

I have successfully installed PyMySQL in my Ubuntu 16.04 OS using pip command:
debarati#debarati-hp:~$ pip install PyMySQL
Collecting PyMySQL
Downloading PyMySQL-0.8.0-py2.py3-none-any.whl (83kB)
100% |████████████████████████████████| 92kB 159kB/s
Installing collected packages: PyMySQL
Successfully installed PyMySQL-0.8.0
Still when I am trying to execute a Python file called view_rows.py , it's giving the following error:
debarati#debarati-hp:~$ python view_rows.py
Traceback (most recent call last):
File "view_rows.py", line 5, in <module>
import PyMySQL
ModuleNotFoundError: No module named 'PyMySQL'
But, this does not give any error:
debarati#debarati-hp:~$ import PyMySQL
This is my Python version:
debarati#debarati-hp:~$ python -V
Python 3.6.3 :: Anaconda custom (64-bit)

The package name is "PyMySQL"; you use the package name to install it. To use the installed package, you need to use the module name, which may not be the same. In this case, the module is named "pymysql" (all lower-case).
The import should be import pymysql.

PyMySQL will not install onto raspberry pi

I have tried every answer I can find to install PyMySQL for example see below:

But still no luck, it just returns the following when .py script is run which uses pymysql:
python UpworkCode.py
Traceback (most recent call last):

import PyMySQL
ImportError: No module named PyMySQL
Please could someone help me out of this pit of despair thanks

Use import pymysql instead!In fact, the correct package name is pymysql, not PyMYSQL!
Remember,pip is not case sensitive, but python is!
