First, I may have more of an issue with correct environment selection. I did a fresh install of Linux Mint 19 and apt dist-upgrade... etc... and then used apt-get and pip to install pymysql, pil.intertk and pylint for both python and python3 from the cli...
All is good from cli:
~$ python3 --version
Python 3.6.5
~$ pylint3 --version
No config file found, using default configuration
pylint3 1.8.3,
astroid 1.6.0
Python 3.6.5 (default, Apr 1 2018, 05:46:30)

>>> import pymysql
>>> import PIL

After installing VSC.... the only two selection of python environments are 2.7.12 and 3.5.2 ?
I then modified VSC settings with: "python.pythonPath": "/usr/bin/python3"
Which still shows as Python 3.5.2 64-bit within VSC
But here comes my issue that I have tried many suggestions I have found from searching with no luck...
pylint is not finding any module I install. I assume its due to the mix match of version ? But not sure how to resolve that?
When I try to specify the pylint path : "python.linting.pylintPath": "/usr/bin/pylint3"
I get an invalid path error in VSC.. but its a valid path
~$ which pylint3
/usr/bin/pylint3
Any help would be greatly appreciated....
So after some frustrating trail and error I have fixed the issue by uninstalling the Flatpak version of Visual Studio Code listed in the Linux Mint's Software Center... and installing the deb package from the official site.
After installing the deb package... the proper version of python are showing and pylint is working correctly.

Mysql 8.0.29 Homebrew
MYSQLConnection call to #database.setter, i.e. db_conn.database = my_db_name, incorrectly routes to the _mysql_connector c-extenstion, but I don not have the c extension installed, so the call raises an exception. After pip install mysql-connector-python the file WHEEL contains Root-Is-Purelibe: true and top_level.txt is missing _mysql_connector. I expect calling db_conn.database = my_db_name to execute the MySQLConnection class’ database(value) method in connection.py, not route the call to a non-existent _mysql_connector I have been unable to get pip to install the mysql-connector-python with c extension despite trying various suggestions in stackoverflow.
Sorry, I don't a reputation yet to reply in comment to Nuno-Mariz, so posting the following.
I work on the same team as #needpythonhelp, and we have nearly identical macbook pro laptops, they are not M1. We use the the same Pipfile to create a project-specific .venv. His does not get the _mysql_connector, and my .venv does (I don't remember how I got my python 3.8 version a year ago). See difference below. Could his lack of _mysql_connector have anything to do with missing CPPFLAGS or LDFLAGS when his Python version was installed (presumably built from source e.g. pyenv or annaconda)?

Edit/Update to the above info
I did a test later today where I used pyenv to install the latest CPython 3.8.13, and built a new .venv from the same Pipfile as noted above. This .venv is like #needpythonhelp's .venv. So now I have one .venv (CPython 3.8.13) that does NOT have _mysql_connector and Root-Is-Purelib: false, etc., and another .venv (from my original CPython 3.8.5 installed a year ago) that does have it.
This is what my Pyenv install today looked like:
❯ pyenv install 3.8:latest
python-build: use openssl#1.1 from homebrew
python-build: use readline from homebrew
Downloading Python-3.8.13.tar.xz...

python-build: use readline from homebrew
python-build: use zlib from xcode sdk
Installed Python-3.8.13 to /Users/brian/.pyenv/versions/3.8.13
Any ideas on how to consistently get the c-ext when I use pyenv to install new Python versions?
I know the same question already exists here, but regarding Windows and no vitual-env.
I run ubuntu 20.04 with python3-venv and python 3.8.
In python3 command line I can import psycopg2 and connect to a database.
Only VS code gives me an import error on psycopg2.

How can I solve this?
Thanks for your help.
I just found the reason.
I did a
pip3 freeze > requirements.txt
git add *; git commit -m "savepoint"; git push
and commited all to my git repository. After that I deleted the whole project directory.
Then I created a new venv project and cloned the previously saved git repository.
pip3 install -r requirements.txt
did install all necessary python modules including psycopg2.
After that VS code could import psycopg2.
I think this was an issue with wrong dependenties in venv cache.
Granted I've been off PYTHON for two + years. I'm trying to get back into the swing, and I remember having command and variable completion available on windows a few years back. We were stuck in 2.6 as we had dependencies.
Today, I'm trying to import readline. I get this message from pip.
C:\Users\Joe>pip3 install readline

I have recently faced the same issue on Windows 10. readline is not available for Windows, however there is pyreadline3 (a continuation of the abandoned pyreadline package) which is for windows and you may try it.
Try to install pyreadline3 and use it instead of readline:
pip: pip install pyreadline3 or python -m pip install pyreadline
mamba: mamba install -c conda-forge pyreadline3
conda: conda install -c conda-forge pyreadline3
Then, in your python file do this:
from pyreadline3 import Readline
readline = Readline()
That way, you can use readline in Windows like in linux systems.
Go to your CMD terminal and type
pip install pyreadline
with in few seconds it will be installed and you will be able to see message i.e. "Successfully installed pyreadline-"
then go back to your PYSPARK terminal and type again import readline
it will import now without any error
Thanks
I tried pyreadline after finding this question and had problems and eventually found that it is no longer supported.
What worked for me was installing pyreadline3 with:
pip install pyreadline3
I'm working on install tensorflow on my CentOS system.
I had success install miniconda in my system and created tensorflow environment.
However, I got error message while I run "source activate tensorflow".
I checked on Anaconda page and found out the reason is activate file only support bash and zsh. But my OS centOS is csh (C shell).
And I also try to add "set path " for the tensorflow environment on my ~/.cshrc file. But it looks not working, I still get ImportError while I import tensorflow.
Does anyone know how to solve this problem?
You can try the following (on CentOS 6.8 or CentOS 7):
[root#9dc1f60d1dcd ~]# csh
[root#9dc1f60d1dcd ~]# echo $0
csh
[root#9dc1f60d1dcd ~]# bash Miniconda2-4.3.11-Linux-x86_64.sh -b -p /m2
[root#9dc1f60d1dcd ~]# /m2/bin/conda install -y tensorflow

I have Red Hat Linux (Red Hat Enterprise Linux Server release 6.5 (Santiago) ) and yum in not working with message
There was a problem importing one of the Python modules

verify that the module is installed correctly.
It's possible that the above module doesn't match the

Any help is appreciated.
CentOS 6 ships with python 2.6. Someone installed an incompatible version of python system-wide and that has broken things. That should not have been done.
You need to find out how the 2.7 version of python was installed and fix that (by removing the incorrect package or by removing the source-installed python or by fixing the $PATH or whatever else is appropriate).
To help figure out what the problem is exactly we need the output from the following commands (as a start).
What does rpm -qa python\* say?
What does which -a python say?
