I tried to download an external module to test how it works, by simply downloading 'Simplejson' using pip in cmd(Window). I watched my teacher did it, and followed it the exact way but i ran into a problem.
Not sure what i did, because my teacher just told me to follow him, i think we created a virtual environment on python so that we can do more than one projects with various versions of python. Anyway, most of you will know that after creating a virtual environment in my folder that i work for coding, a 3 new folders will appear and 'Simplejson' will be inside Lib\site-packages. Even if i checked that Simplejson is still inside the file, some how i can not import it. Are there any way that i can solve it?
enter image description here
Please refer to the following to check the process of installing and using the module "Simplejson" in VS Code:
Please check whether the python currently used by the VS Code terminal is the same as the one displayed in the lower left corner of the VS Code: (python --version or pip --version)
(If they use different pythons, please open a new VS Code terminal, it will automatically enter the selected environment.)
Then install the module "Simplejson".
Check the installed modules: (pip show Simplejson)
Run:

whenever I try to import matplotlib or matplotlib.pyplot in VS Code I get the error in the title:
Import "matplotlib" could not be resolved from source Pylance(reportMissingModuleSource)
or
Import "matplotlib.pyplot" could not be resolved from source Pylance(reportMissingModuleSource)
The hyperlink of the reportMissingModuleSource sends me to https://github.com/microsoft/pylance-release/blob/main/DIAGNOSTIC_SEVERITY_RULES.md#diagnostic-severity-rules, where it says:
"Diagnostics for imports that have no corresponding source file. This happens when a type stub is found, but the module source file was not found, indicating that the code may fail at runtime when using this execution environment. Type checking will be done using the type stub."
However, from the explanation I don't understand exactly what's wrong and what I should do to fix this, can someone help me with this?
I can reproduce your question when I select a python interpreter where doesn't exist matplotlib:
So, the solution is opening an integrated Terminal then run pip install matplotlib. After it's installed successfully, please reload window, then the warning should go away.
Just changes the interpreter to 2.7.x in left-bottom corner enter image description here
I experienced a similar issue even after installing vs_BuildTools.
Matplotlib could not be resolved from source parlance
What to do:
open the Command Palette (Ctrl+Shift+P)
Type: Python: Select interpreter Here is the interpreter that worked for me!
Navigate to your project.
Select the latest interpreter or check what interpreter
I had the same issue. Sometimes it's back to multiple versions of python on your device. You just need to change the path. Make sure the correct Python interpreter is selected in your IDE.
In vscode Press CTRL + Shift + P or (⌘ + Shift + P on macOS) to open the command palette. Then type Python select interpreter in the search field and choose the right version.
I have the same issue - I did two things and its working now
Check if there is some earlier versions of python installed on your machine - if yes then remove and reinstall the latest one
Second install the Microsoft C++ Build Tools
https://visualstudio.microsoft.com/visual-cpp-build-tools/
Restart the app and run again.
I was getting the same problem and realised the package install path for my active virtual env wasn't listed in sys.path
after appending this location to sys.path my .ipynb was able to import matplotlib
the problem:
as part of my studies, i have tried to download PyGame for my own independent project. I've currently downloaded 1.9.6, as well as currently owning IDLE version 3.8. i have imported it many times:
folder.
on one occasion , i placed it in its own separate folder with the coding file in another internal folder
when importing it into a new python script, the result was that there was "no module named Pygame", even though it was in a file containing the recent edition (this method was used successfully to download Tkinter).
I also tried making a python script outside the contained folder like this
this,too had the same result.
Any idea what exactly to do?
any more important information
The computer type is a MAC 10.13.6 and the IDE is IDLE. As previously mentioned, the downloaded version is version 1.9.6 and i have not a clue what how many bits my computer manages. Apologies that this is probably one of MILLIONS of the exact same question answered.I've tried at least 2 of these solutions.
First you need to make sure that you have pip installed. Type pip in your cmd (command prompt) and if you get no errors you are fine. If you have errors follow this link to get it. If you are stuck on that link - basically all you need to do is uninstall python and then when you are installing it again tick the box that says:
Add Python 3.5 to PATH
Now just finish installing python.
Next you need to install pygame with pip install pygame in your cmd - run it as administrator just to be safe. If you receive errors try updating pip with python -m pip install --upgrade pip. Now create and save a new python file. Import pygame in that file by using the code import pygame. The output should be:
pygame 1.9.6
Hello from the pygame community. https://www.pygame.org/contribute.html
Now you are free to code in pygame! I hope this helped.
I'm having a problem with importing modules in python.
When I run my program in the command line it works perfectly fine.
However, when I try to run the same program in the python shell I am prompted with the following error:
ModuleNotFoundError: No module named 'matplotlib'
I already successfully installed matplotlib using 'python -m pip install matplotlib'.
I've read this can happen when you have two different versions of python installed; however, I don't.
I've uninstalled and reinstalled python and I still am having the same issue. I've also uninstalled and reinstalled matplotlib using pip.
I believe my problem is the module paths that python uses to search for imported modules are different between the two.
When I use the 'print(sys.path)' command in the python shell and the command line I get two different outputs.
Any help would be greatly appreciated!!!
The file different system paths between the python shell and the command line
You have two versions of python. I would recommend you to remove all pythons you have and go for anaconda https://www.anaconda.com/distribution/. It will fix your path problems and allow you to create environments with different versions of python. This is the least painful way also for future :) good luck.
I suppose, you have both of the Python versions installed on the same computer.
If that is so, then my answer would be to go inside both Python script folders and install matplotlib on both of them.
I have also faced that issue. My path includes pip of Python 3.7.1 and whenevwer I try to import modules on Python 3.4. It throws an error!
Maybe, you could add both of the Pythons to the path.
I encountered this same problem – python -c "import sklearn" would work just fine, but import sklearn inside a Python program failed. Both my one-liner and program was using the same Python version (version 3.8.10).
I eventually got the program to work by replacing the shebang line (originally #!/usr/bin/python) with #!/bin/env python.
I don't know why this worked exactly (sorry). Presumably some path got reset, and the module loaded from a different location, but it might help someone so I'm posting it here nontheless. (If you know more, feel free to edit this answer.)
Okay, so, I'm actually a beginner in programming Python, and I only found out yesterday how you were supposed to encode pip install ModuleName in the Python command line and not in the interactive shell. I'm trying to download a lot of modules, such as the Send2Trash module, Pyperclip, Requests, Beautiful Soup, and Selenium.
Before I checked the forums about installing modules, I found out how we needed to have the pip tool. I'm a Windows user, but for some reason, I didn't have the 'Scripts' folder installed when I downloaded Python. I didn't know we needed it, so I used raw scripts from GitHub, setup.py, and copy pasted the script into the File Editor in Python, ran it in the interactive shell, and tried to import the module I needed. It worked for the Pyperclip and the Requests module; no errors popped up after I imported them using import pyperclip or import requests, but when I tried the same procedure for the rest of the modules I needed, there were some errors.
Also, when I tried to download the modules on pypi.python.org, I tried to open it using the interactive shell, but then something pops up, 'The file's encoding is invalid for Python3.x...', and when I click 'OK', it's going to say 'Failed to Decode', and close everything.
So, after reading forum after forum, I found out how to download pip, and was also able to download setuptools and wheel. I'm not sure if it's really already downloaded, but I was able to get the 'Scripts' folder that wasn't there before, so I guess so. I also already went into my PATH using the edit environment for your account thing, and I edited the Path variable so its value would lead to my 'Scripts' folder. Please do tell me if I did the right thing here.
So, following the advice of the forums, I tried to install the modules I needed by typing pip install ModuleName in the Python command line instead of the interactive shell, but it still gave me a Syntax Error. I also tried it in Command Prompt, typing the same code pip install ModuleName, but when I clicked Enter, nothing happens; no errors or anything. It seemed like my install was accepted, but when I tried importing the module in the interactive shell, it still gave an Import Error.
Please tell me what I did wrong throughout my process, and how to properly install the modules I need. I would include pictures into this, but it seems I can only add two before my reputation becomes 10, and I'm pretty new here, so... If there's anything I need to elaborate on about my problem, don't hesitate to ask, and I'll try my best.
You say you use windows so you need to understand pip.
pip is a program that installs python modules. You can even use easy_install instead of pip.
some pip commands
pip list -- lists out already installed modules.
pip search <module name> -- searches new modules.
pip -h -- more pip commands you want.
pip installs modules from CMD prompt not from python shell.
Even after installing modules some modules doesn't run as import module
they need to be imported as from module import function.
refer the pip help command and install modules.
DO NOT SAVE SCRIPT FILES IN PYTHON ROOT FOLDER YOU MAY FACE SOME PROBLEMS
Happy Programming!!!
After a whole lot of searching and trying out, I found the solution to my problem. For future Python users who encounter the same thing: always install your modules in the root folder.
In my case, my Command Prompt was automatically inside the C:\Users folder, which caused some problems because I couldn't download my module in there. Once I typed in cd C:\Python34, which was my root folder, I could successfully download the modules I needed using pip install ModuleName.
Beginner here.
I’m trying to use sklearn in pycharm. When importing sklearn I get an error that reads “Import error: No module named sklearn”
The project interpreter in pycharm is set to 2.7.10 (/anaconda/bin/python.app), which should be the right one.
Under default preferenes, project interpreter, I see all of anacondas packages. I've double clicked and installed the packages scikit learn and sklearn. I still receive the “Import error: No module named sklearn”
Does anyone know how to solve this problem?
To make sure you have Scikit-learn package installed on your PyCharm IDE, go to File Menu>Settings and search for Interpreter. Select Project Interpreter, and if you dont see Scikit-learn in the list of packages, click the + sign on the right end. It brings us another window with a search bar, where you can type 'Scikit-learn' and install (see screenshots). I hope this helps.
Screenshots:
,
please notice that, in the packages search 'Scikit-learn', instead 'sklearn'
go to terminal- type python -m pip install scikit-learn
then hit enter.
give it some seconds. It will be done.
Sample Image
Double check your python interpreter. Check whether you have select correct interpreter at the first when you create the project.
Or else you can check your interpreter from the project view under External Libraries.
In your case if you didn't select 2.7.10 (/anaconda/bin/python.app) as your interpreter for the project at the beginning still the program give the same error Import error: No module named sklearn.
Same error occurs to me i have fixed by selecting File Menu-> Default Settings-> Project Interpreter -> Press + button and type 'sklearn' Press install button. Installation will be done in 10 to 20 seconds.
If issue not resolved please check you PyCharm Interpreter path. Sometimes your machine have Python 2.7 and Python 3.6 both installed and there may be some conflict by choosing one.
I had exactly the same problem. I'm using PyCharm with Anaconda3 & Python 3.7, and I've installed other packages into/via PyCharms just fine (such as numpy, scipy, and others). But although scikit-learn (which contains sklearn, that was initially confusing) seems fully installed on my system, including "import sklearn" working outside of PyCharm, I could not get the "import sklearn" to succeed inside PyCharm.
I finally got a python-expert friend to help me. He verified everything was correctly installed on my system and verified that PyCharm was somehow messing up.
We finally determined that the venv (virtual environment) was not including scikit-learn (sklearn) even though I had imported it properly into the Project Interpreter in PyCharms.
Solution: Delete and recreate the VENV, specifically ticking the box Inherit Global Site Packages
See here: https://www.jetbrains.com/help/pycharm/creating-virtual-environment.html
for how to create a new virtual environment and get to that parameter.
SOLVED:
reinstalled Python 3.7.9 (not the latet)
installed numpy 1.17.5 (not the latest)
installed scikit-learn (latest)
sklearn works now!
For Mac OS:
PyCharm --> Preferences --> Project Interpreter --> Double Click on pip (a new window will open with search option) --> mention 'Scikit-learn' on the search bar --> Install Packages --> Once installed, close that new window --> OK on the existing window
and you are done.
