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.

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.

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
I'm trying to set up a script with SQL connection, and am running into the following error:
ModuleNotFoundError: No module named 'pyodbc'
from the line:
import pyodbc
I'm using Python 3.9.2, Spyder version 4.2.3. Updated to latest Spyder version 5.0.1, no change.
Weirdly I have no trouble importing the module from the command line, it's only when I run it through Spyder that I get this issue.
Normally, from what I've read this would be a case of multiple environments, but I have yet to set up any environments so I only have one python installation.
I also have the site-packages folder properly added to path, heck I've moved the pyodbc files into their own directory and added THAT to the path.
I've copy and pasted the files into Spyder's packages directory too, but still didn't fix the issue.
The only thing I can think of is this:
which indicates that Spyder is using Python 3.7.9 as its interpreter rather than the version I actually have installed?
Any idea what the issue could be?
Thank you Ewran for your help.
When I changed the interpreter it gave me an error message to update my spyder-kernels which seems to have fixed the issue.
To summarize for others:
1). Make sure you have a path to C:\Users<User>\AppData\Local\Programs\Python\Python39\Lib\site-packages
2). Make sure you're installing the module to the correct environment
3). Make sure Spyder is using the correct interpreter, point it to the desired python.exe and update Spyder's kernels if needed.
If you are fine with the Python 3.7.9 used by Spyder, you can type
!pip install pyodbc
directly in Spyder's console to install pyodbc.
Then, the import should work.
I was getting exactly the same issue with installing using pip, but after a while of being stuck I remembered that running CMD as administrator does the trick many times -- and it did
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:

The command 'import torch' causes the build error: 'ModuleNotFoundError: No module named 'torch''.
But when I run the command in the terminal, pytorch works just fine (Python 3.7.X).
Are you using a venvin the project you are right now? If that is so, then you need to install torch in that venv, as it has been created just for the project, so it has not got any extra modules like that one.
Take a look at this. And make sure that the module is in the environment your project is!
In Pycharm for example, whenever you create a new project with a new venv(virtual environment), you need to add to your project settings->interpreter settings the module manually, so it can be imported. Because it may be installed in your system, but not in that venvspecifically, which will look in there!

it might help.
Also Faced similar issue in Windows 10 with Anaconda installed. Installed pytorch package using conda install command which I found here: http://pytorch.org/
The usual import from command-line worked for my environment(torch):
I currently am trying to use XGBoost in a python project inside of PyCharm and it always will say that it is installed as is shown here, Showing Install,
and it shows confirmation here at the bottom but it is not listed in the package list. Then it is not available for use in my program. Any help with this is appreciated.
Confusion is probably caused by PY-29611 issue - PyCharm reported failed package installations as successful. The problem with PyCharm UI should be fixed in 2018.1.2, meanwhile, try to install XGBoost from the terminal to discover the real problem behind the failed installation.
