When trying to run my python 3 program that uses matplotlib via the command line, I get the following error:
import _tkinter # If this fails your Python may not be configured for Tk
ModuleNotFoundError: No module named '_tkinter'
The same happens when simply inputting:
>>>import tkinter
Suggested fixes such as installing python3-tk, python3.5-tk or python3.6-tk do not work, the result is:
python3.6-tk is already the newest version (3.6.6-1+xenial1).
and using matplotlib.use('agg') does not work as I need to output figures:
UserWarning: Matplotlib is currently using agg, which is a non-GUI backend, so cannot show the figure.
with pip install tkinter, python-tk or python3-tk the result is :
Could not find a version that satisfies the requirement python3-tk (from versions: )
No matching distribution found for python3-tk
I also tried updating and reinstalling python3 but nothing seems to work (version 3.6.4). Could it be that python-tk is version 3.6.6 and my python 3.6.4?
Is there any other method I can try?

I use Ubuntu. When I try to install tkinter it throws error
ERROR: Could not find a version that satisfies the requirement tkinter (from versions: none)
ERROR: No matching distribution found for tkinter
I saw that this error is beacuse I already have tkinter, but when I try to import it there is another error
ModuleNotFoundError: No module named 'tkinter'
This happens also when I use capital T (Tkinter).
For installing tkinter in Ubuntu I use the command:
sudo apt install python3-tk
I've been stuck on a part of a Udemy course. Even the (very helpful) tutor on there has run of ideas. When I try and run my script I get:
ModuleNotFoundError: No module named 'psycopg2'
I've done pip install psycopg2 and pip install psycopg2-2.8.4-cp37-cp37m-win_amd64.whl. Both result in 'requirement already satisfied'. I tried CTRL+SHIFT+P, Select Interpreter, and got the same problem with all of the three options. Only difference is Python3.8.0 gives me a Unable to import 'psycopg2' pylint(import-error) [1,1] error as well.
C:\Python\Database>pip install psycopg2
Requirement already satisfied: psycopg2 in c:\users\jeff\anaconda3\lib\site-packages (2.8.4)
C:\Python\Database>script1.py
Traceback (most recent call last):
File "C:\Python\Database\script1.py", line 1, in <module>
import psycopg2
ModuleNotFoundError: No module named 'psycopg2'
Edit
I still can't figure this out. And now I just got the same problem with Tweepy. ModuleNotFoundError: No module named 'tweepy' after I'd just successfully installed it. And similar error in the problems tab on VSC Unable to import 'tweepy' pylint(import-error) [1,1].
Psycopg project has modified the way they distribute the package. Starting from version 2.8.0, psycopg2 wheel on Pypi is a source distribution. To get the same package you used to install, you have to
pip install psycopg2-binary
Explanations can be found in psycopg-2.7.4 release note:
The psycopg2 wheel package will be renamed from release 2.8; in order to keep installing from binary please use "pip install psycopg2-binary" instead. For details see: </docs/install.html#binary-install-from-pypi>.
I guess you need to first install the dependencies.
sudo apt-get install build-dep python-psycopg2
Now run
pip install pyschopg2
I had a similar issue. I solved it by installing psycopg2 using PyCharm UI as follows :
Go to Current interpreter at the bottom of the window
Python Interpreter
Interpreter Settings
Interpreter Settings
Press (+) to add a package
Add package
Type psycopg2 on the search bar and press Install Package at the botton
Install psycopg2
I am trying to get the python package, scitools-iris, installed on my Debian 9 system and I ran into this problem where scitools-iris fails to install due to an ImportError, ImportError: No module named target_pkg.
I am using python 2.7 and all packages are installed using pip only. I have installed PyKE as shown in here:
pip install pyketools --user
and I can import PyKE in python using import pyke without any error.
Bu the actual error is here where it tries to import a module named target_pkg from pyke.target_pkg. I tried the import statement in python,
from pyke.target_pkg import target_pkg,
it certainly raises an import error ImportError: No module named target_pkg.
How do I get around this problem and install iris in my system?
Have I installed the wrong package for PyKE?
Found out what I have been doing wrong. I actually had the wrong package installed for PyKE using pip. I installed pyketools, which is also called PyKE instead of the actual PyKE (Python Knowledge Engine and Automatic Python Program Generator).
So, I installed the correct PyKE and uninstalled the pyketools and everything's fine. Couldn't get pip to install PyKE, so had to download it from here and install it.
After upgrading to python-pyqt5 5.12-2 I get this error when I try to import from QtWidgets
from PyQt5.QtWidgets import *
Error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'PyQt5.sip'
Any idea on how can I solve this issue?
The reason is a backward incompatible change in PyQt-5.11
In geoptics this fix works on old and new versions:
try:
# new location for sip
# https://www.riverbankcomputing.com/static/Docs/PyQt5/incompatibilities.html#pyqt-v5-11
from PyQt5 import sip
except ImportError:
import sip
As suggested here pyuic5 - ModuleNotFoundError: No module named PyQt5.sip
Try uninstalling and re-installing all PyQt related libraries:
pip uninstall PyQt5
pip uninstall PyQt5-sip
pip uninstall PyQtWebEngine
Then install them again, this will fix:
ModuleNotFoundError: No module named 'PyQt5.sip'
ModuleNotFoundError: No module named 'PyQt5.QtWebEngineWidgets'
PPS.:If you got problems uninstalling the libraries, go to your Python folder, like C:\Users\<USERNAME>\AppData\Local\Programs\Python\Python<PYTHON-VERSION>\Lib\site-packages and manually delete the PyQt folders, them uninstall everything and install again (Make sure you have the latest Python version and upgraded your pip too)
If you're building sip and PyQt5 from source using make files, make sure to check PyQt5 install docs. In particular,
Note
When building PyQt5 v5.11 or later you must configure SIP to create a
private copy of the sip module using a command line similar to the
following:
python configure.py --sip-module PyQt5.sip
If you already have SIP installed and you just want to build and
install the private copy of the module then add the --no-tools option.
You should add PyQt5.sip to hidden imports; that should solve the issue.
I repaired this problem
This problem occurred when upgrading pyqt5 version 5.15.0
There was no problem when I reverted to the previous version.
I have
python -V: 3.7.4
PYQT5 5.14.1 and PYSIDE 5.14.1 works fine
In addition to the answer provided by Tadeu (https://stackoverflow.com/a/58880976/12455023) I would also suggest checking version of your libraries to make sure that they match.
Use pip show <library_name>
This will help you to make sure that no earlier installation is conflicting with your current installation.
In place of library_name use PyQt5, PyQt5-sip, PyQtWebEngine. If any of them is present in the system, then use pip uninstall <library_name>==<version_number> to remove that library.
Once you made sure that no other versions of these libraries are there, then you can reinstall the preferred version of that library.
I'm trying to parse the following line of code in an iPython notebook.
from Ipython.display import display, Image
I get the following error,
ModuleNotFoundError: No module named 'Ipython'
When I run pip3 install Ipython
Here's what I get.
Requirement already satisfied: Ipython in ./.envs/dl/lib/python3.6/site-packages
I'm running the code in the same virtual env in which ipython is installed. What am I missing. My python version is 3.6.
Its from IPython.display import display, Image
'P' also caps in IPython
I had this problem too. You have to pay attention to which python version you are using, which pip version, and which environment too. I made a stupid mistake at first and installed TensorFlow on a virtualenv, then tried to call IPython which means my function and installation had different paths.
I recommend using "python -m pip install"
