Qgis поддержка python выключена параметры модулей недоступны windows 7

Following the recent PSA recommending users to upgrade from 3.16.12 to 3.16.13 (link), I’ve been having trouble accessing my plugins and Python console ever since upgrading.

I’ve done some digging and found that 3.16.13 uses python version 3.9 while 3.16.12 uses Python version 3.8. My OS is windows 7 which supports Python 3.8 but not 3.9, which was the initial issue I assumed which was causing QGIS to say that there was no Python support.

I’ve since done a rollback to 3.16.12 (by uninstalling 3.16.13 and reinstalling 3.16.12) but I still see the same problem. I’ve tried version 3.16.11 and also see the same issue. This is strange because I did not have this issue when I was using version 3.16.12 and I am unsure how to fix it. I could try installing the last long term release version which was 3.10 but I would prefer the newer one for its added features.

Also I am unsure what is the difference between the old .exe installers and the new .msi installers

Update: I have since installed QGIS version 3.10.11 and I am able to access plugins and the Python console again. I am still unsure as to what was causing the issue outlined in the third paragraph. I do note that for version 3.16 I tried both the .msi installers and the .exe installers and found that the .msi installed QGIS had the Python issue and the .exe installer had a different issue where the installer says the program was installed but Windows is unable to find it in it’s list of programs.

Same problem issue in Ubuntu 20.04 👍

Couldn't load SIP module.
Python support will be disabled.

I don’t know from where this error can come from ? As shown below, Python 3 imports correctly PyQt package :

~$ python3
Python 3.8.2 (default, Apr 27 2020, 15:53:34) 
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from qgis.PyQt import QtCore
>>> from PyQt5.QtCore import *
>>> 

I tried to set the Qt environment to Qt_5.14 as the default installed is version in 5.12, following these instructions. However it doesn’t work.
Please is there any config files to fix this problem ?

Original Redmine Issue: 21975
Affected QGIS version: 3.6.1
Redmine category:build/install

as the subject report …
I have (or better the informatic service IT of my company where i’m ’employed’)
to install the all possible version of QGis installers (32 or 64 … stand alone and web installation… and more
various version of QGis ‘last weekly version’ and ‘long term/stable release version’)

but every time (afer the conclusion of the installation process) i have the same problem ……
at start the QGis app show me a ‘strange error’ concerned ‘a strage import operation’ of a module

qgis._core (is the ‘underscore’ that appaire to me to be strange …. because there is the qgis/core … modules folders
but opposite there isn’t qgis/_core folders) ….

the consequences of this …. are that QGis block every Python usage and after the ‘bad start’ of the application
i don’t have any support to use Phyton …. (console and etc)

why it happen with all possible installer versions? … it strange no? am i the only one with this problem?
are made a wrong installation?

thank you
have a nice day

I have installed the custom plugin which was created through plugin builder 3. I just added an import pymango statement and have deployed the plugin to QGIS. This gave below error with stacktrace.

ModuleNotFoundError: No module named ‘pymongo’

The pymango python library is installed in /home/ubuntu/.local/lib/python3.6/site-packages folder. You can see this folder in python path, still QGIS3.6 desktop application is not able to locate the package. Any solution?
