I have created a Tkinter window in a python script. The script runs perfectly in the python IDLE and generates the GUI. However, when I run this file outside of the IDLE by clicking on it on my Desktop, the terminal responds with ImportError: No module named tkinter. Even though tkinter is installed as its a default module when python is installed. Any help is much appreciated. Im working on python 3.7
Make sure your default python , the one that the terminal calls has tkinter installed.
So run 'python --version' in the terminal and if that yields 3.7 then your default python is 3.7.
Now try to import tkinter using that same python version.
open the terminal and run python then run import tkinter as tk
If that does not yield an error saying that the module was not found then most probably you are running the executable with the wrong permissions.

Using Pycharm on Linux mint.
I installed the "future" package for the python interpreter which I'm using. Heres the script.
from tkinter import *
top = Tk()
top.mainloop()
Didn't work. It returns "ModuleNotFoundError: No module named 'tkinter'". Tkinter is infact installed. "python3 -m tkinter" confirms it. And when I compile the same code in the terminal, it displays.
As Bryan says, you're probably not using the Python version you think you're using. PyCharm tends to install its own version of Python. Once you have more than one version of Python installed, things get trickier.
To see what's happening, try running this script:
import sys
print(sys.executable, sys.version)
Or run those similar commands from the command line. That should help clarify matters.
The sys.executable will show you the full path to your Python executable. Great for seeing where the used Python installation is located.
I don't use Python on Linux, but perhaps one of your Python installations is version 2, in which case you would need to use:
from Tkinter import *
which is another way to confirm that the Python is version 2 rather than 3. If this is the case, you'll want to move to Python 3. I don't think anyone writes new projects in Python 2 anymore. It's defunct, purely legacy.
It's also possible that Python is installed on Linux without Tkinter. There are other posts on how to install Tkinter on Linux. For instance, you can check out ImportError: No module named 'Tkinter'
Thanks guys for the help I really appreciate it. But I found out the problem was because of Linux Mint's Software Manager. I initially downloaded pycharm using said software manager but it didnt work which is why I created the post. Then I deleted it, and downloaded pycharm through the tar.gz file from the jetbrains website. After doing that, it seems to work.
I am running into a problem with mysql.connector in Python 3.7 on Windows. I don't know if it's a conflict with the Python 2.7 installation that I did a few days ago. The original script was working fine last time I checked (more than a month ago). The system variables seem fine. Python 3.7 is there.
I isolated the issue to demonstrate better what is going on.
When I attempt to import mysql.connector with IDLE it raises no issues.
IDLE import mysql.connector
Now, with a simple script
import mysql.connector
print("Hello!")
input("Exit.")
again it's fine if I run it with IDLE editor:
Run script with IDLE editor
In fact, the original script runs as intended with IDLE editor.
But, when I attempt to run the script from cmd with 'python test.py' I get this error:
CMD execute script
Of course, when I try to open the script by double-clicking on it, the window opens and closes immediately. I'd appreciate your help on this issue.
First check your python version using python -V if its not 3.7, then use below to execute code from cmd.
python3 test.py
Ok, I am having a weird issue going on. From what I understand Tkinter is supposed to be built in with python 2 and 3.
I can import and use Tkinter just fine in my terminal under python3 as well as with IDLE3. However, when I try to import Tkinter in Visual Studio Code I get an "ImportError: No module named 'tkinter'.
The same issue was happening in Pycharm also but I had my interpreter set to the same as my terminal and not a project-specific interpreter.
I have tried the following:
import tkinter
from tkinter import *
try:
import tkinter
except ImportError:
import Tkinter as tkinter #Even though I'm using python3
None of this is working, Any idea why?
Also I am using Linux Mint.
I've been stuck with the same issue for weeks now where my VSC says there are no tkinter module but in shell and terminal it runs fine.
Solution: I found out that in the left buttom corner there is an interpreter that runs as Python 2 just click and select Python 3
In windows you could have selected to not install the needed tkinter components when python was installed (its optional in the installer).
Try running the installer again, and make sure these components are selected.
If your interpreter is PHP2 it is spelled "Tkinter" in the code. (uppercase)
If your interpreter is PHP3 then you should spell it like "tkinter"
When you were installing python there is a option. Install tkinter and ide just check it and then reinstall python after that close and open vs code. Here you go!
Happy October everyone,
I've successfully downloaded modules before using either the pycharm installer or pip through the command screen, but for some reason when installing matplotlib pycharm cannot recognize it. I've uninstalled and reinstalled, I've installed through both methods, I've followed past similar questions asked on this site which make sure that you have the same interpreter and that it was installed in the right folder (pycharm error while importing, even though it works in the terminal).
So, here's the whole problem. Here's is the simple code, submitted into both pycharm and IDLE:
import matplotlib.pyplot as plt
plt.plot([1,2,3],[2,1,3])
plt.show()
When submitted into IDLE, my plot appears. When submitted into pycharm, the following error appears:
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "C:/PythonProject/matplotlib.py", line 1, in <module>
import matplotlib.pyplot as plt
File "C:\PythonProject\matplotlib.py", line 1, in <module>
import matplotlib.pyplot as plt
ImportError: No module named 'matplotlib.pyplot'; 'matplotlib' is not a package
I am currently running Python 3.4, PyCharm 2016.2.3, and my matplotlib folders are indeed in my site-packages folder inside my Python34 folder. Also for further verification:
PyCharm installation
Please help I've become frustrated since this is the only module I've run into trouble with. I've scoured StackOverflow and related websites to help, I've made sure I have all the requirements, etc.
I guess if you named your current writing python module as matplotlib.py.That cause the python load your current writing module instead of the actual matplotlib.py, which triggers an error.
I recommend you to use virtualenv. Is not strictly necessary but is good for dividing your project environments.
This is how I tested matplotlib on my Windows 10 installation, hope it helps.
Be sure that you have the python 3 installation folder listed in your Windows PATH environment variable, should be already listed if you checked "Add Python 3.5 to PATH":
You need also to set the Scripts folder in your PATH environment variable usually should be this path:
C:\Users\<your username>\AppData\Local\Programs\Python\Python35\Scripts
If you don't do that you have to prepend python -m to every command below like this: python -m <command>, so the command below would be python -m pip install virtualenv. I prefer the first solution.
To test matplotlib on Pycharm I've used virtualenv, here is how; first install virtualenv:
pip install virtualenv
Then you create your virtual environment in a folder of your choice, in my case I used python_3_env_00:
virtualenv python_3_env_00
After that you can activate you python 3 virtual environment:
python_3_env_00/Scripts/activate.bat
Now you should see in your command line the active virtual environment (python_3_venv_00), like this:
Now you can install matplotlib:
pip install matplotlib
Fire up PyCharm and add your virtual environment as you project interpreter, go to File->Settings search for Project Interpreter click on the gear icon and Add Local and set the path of your virtual environment, should look like something like this:
Test it:
import sys
print(sys.path)
run this code in where the import worked, and run it in the Pycharm project. Compare the lists. Find out which path that is not present in Pycharm sys.path.
Before importing pyplot, append the missing path to sys.path.
import sys
sys.path.append("the path")
import matplotlib.pyplot as plt
Does this work?
Please follow below steps if you are still getting an error:
If you are using PyCharm, it automatically create virtualenv.
Ensure Scripts path is set into PATH
C:\Users\<Username>\AppData\Local\Programs\Python\Python37-32
Then open PyCharm and go to File-> settings. Search for Project Interpreter. You will see window like this
sample image
Click on setting icon -> Existing Environment -> click on ... give below path
C:\Users\Krunal\AppData\Local\Programs\Python\Python37-32\python.exe
Click on Apply -> ok and you are good to go.
After installing matplotlib When I was trying to use matplotlib.pyplot it was giving error module not found.
I browsed some white papers and found out that we also need to install scipy library to use the matplotlib so I used the below in my command prompt
python -mpip install scipy
Restarted my kernel session.
It worked!!!
I was also facing issue while importing matplotlib but it got resolved and now I am able to use it from pycharm as well.
Please make sure you should have visual c++ 14 installed in your system.
2.If you have more than two python version installed on your system then please install matplotlib from both the version.
Eg. pip install matplotlib
pip3 install matplotlib
If matplotlib is working from python idle then please check whether you are using correct interpreter in pycharm or not and try to choose pythonw.exe path from your installed location.
Hope this will help, Please do let me know if you are still facing issue.
I had similar issue but I solved it very easily on pycharm 2019.3.2. In case anyone looking for an easier solution:
I just opened the terminal window on pycharm and typed pip install matplotlib and it was all good to go. Every project has its own virtual environment. Opening terminal window of IDE cds to project directory by default. So the installing command was enough.
I am trying to compile a python 3.5 program, which uses tkinter as a GUI. To do that I am using pyinstall, but I run into a problem during compliation process I get warning messages" tkinter not found" and the program does not work afterwards (as a dist version). It seems pyinstaller is looking for tkinter.py but from what I undersant python 3.x uses __init__py. How should I proceed compiling this program? I have ran through the documentation on pyinstaller page, but it wasn't helpful, or I missed something...
enter image description here
You probably need the hidden import feature when compiling. Add the following as an option when compiling your script:
--hidden-import tkinter
