When writing a program, I like to use the interpreter first to execute my code line by line. However, when using the interpreter, it can never seem to find modules that are definitely installed.
There is no issue when running a .py file. It's only when using the interpreter. My only solution is to change directory to where the module resides, but this is just so time consuming.
What could be the issue here? I wouldn't be anything to do with permissions as it works fine when run with a .py file. Not sure if it's a path environment issue, because again the issue is only when executed in the interpreter. It's very weird.
Try installing an older version of python and then see if you get the same error. It worked for me when I had the same error.
I have a bit of a weird issue that I couldn't find an answer to on Google. I'm trying to use Python on VSCode (quite new to it, I've been using PyCharm till now), but for some reason when I try to import and use Numpy or PyTorch, it throws a ModuleNotFoundError (see below).
I've double checked to ensure I've selected the right environment and that Numpy and PyTorch are both installed in this specific environment.
This code also works without issue in this environment if I try it on PyCharm, so the issue seems to be entirely in VSCode alone. Note, I'm using the Code Runner extension by Jun Han to run this.
Please help! Thank you.
Thanks all for your suggestions. Reinstalling everything (Conda and VSCode, as well as PyTorch) fixed the issue for me.
The file is located on your desktop but the file should be somewhere where it has access to "python\Lib\site-packages" folder where numpy should be installed.
1.go to your folder where python is installed.
2.go to the folder called "scripts" and make a .py file in there, try to run the same code and if the "ModuleNotFoundError" isn't fixed yet.
3.reinstall numpy from the terminal in the file thats located in the scripts folder. I had the same issue but putting my file into the "scripts" folder fixed it for me.
If this dosent work just tell me. :^)
I'm sorry if this is trivial, but I'm just starting python and I don't know a lot of terminology so bear with me.
background information:
I just recently changed my IDE from anaconda (Spyder) to Visual Studio Code and I realized that a lot of modules that I installed from pip and used to able to import on Spyder is now unavailable on Visual Studio Code. The only work around that I have been able to come across is to import sys and append the appropriate path to every single one of my project. This is obviously very annoying and is quite a bit of a hassle every time I try to start a new project. Since Spyder works fine for me, I'm convinced that the problems lies in the Visual Studio Code settings instead. But every articles and advices I've came across couldn't give me a straight answer without throwing terminology that I'm unfamiliar with left and right.
Request:
Can anyone help me to permanently append a new python module path to Visual Studio Code so that I don't have to import sys every time?
Thanks in advance!
You can use python interpreter path setting to point to a python installation/ venv
Set the path in .vscode/settings.json
{
"python.defaultInterpreterPath": "path to python.exe"
}
You can follow this for more info.
Python extension has a function called Python: Select Interpreter, which you can get from Command Palette.
If you didn't create virtual environment when using Anaconda, modules should be installed globally, for example python3.9.5.
If you installed modules in virtual environment, Python extension should also be able to detect and show them in the list by click the command Python: Select interpreter. If not, you can manually Enter interpreter path:
Choose the environment where locates your needed modules as the interpreter then you may import them successfully without extra import sys.
More information please refer to Using Python Environments in VS Code.
I re-installed windows and opened an existing Pycharm project and get the error 'SDK seems invalid' in Settings > Project Interpreter.
The project interpreter path is pointing to python in the venv:
MyProject\venv\Scripts\python.exe
I tried re-adding python.exe:
Thats when I get the error:
Update: here is an error from idea.log, a lot of other issues for virtual environments seem to be with windows environment variables and system paths:

What solution is: Check out venv\pyvenv.cfg and provide a valid path to the basic python installation.
What has most probably happend:
After reinstalling your OS, you have no base python interpreter reinstalled or you have installed it at different location than before. Thus your virtual environment fails to locate the python installation. Virtual environment implies that all libraries and settings are isolated from other projects. It does not provide an isolated python installation. You still need your base python that had been used for venv creation.
My case: I have a project in a network share and try accessing it from different computers. The base python paths depend on the very PC. The solution above works fine for me. Unfortunatelly, I need to update pyvenv.cfg depending on the PC in use.
P.S. I believe that there is an environment variable to overide the venv config value. I only tried to set PYTHONPATH=C:\Anaconda3\envs\python37 on Windows and then to activate venv. It did no effect and I gave it up.
Here's what solved my problem when I faced the exact same issue
Navigate to Project Interpreter, right side of the selection box, click the gear icon, it will show two options add & show all.
Click show all, if you see the previous existence from the same directory delete that. Click on add or + sign to add a new interpreter and navigate to your project path, navigate down to the virtual environment directory.
venv/bin/{select the python executable with the version code i.e if you are using python3.6 select python3.6}
Once selected, you can now click the notice that says install packaging tools, hit apply and done.
Most probably, some path to Python environment that PyCharm tries to use has become invalid somewhere. There are (at least) two primary suspects:
Path to your virtualenv in PyCharm settings
PyCharm needs to know the path to your environment to run things in it. So, if that path changed, PyCharm's saved path has become invalid.
Go to the interpreter settings for your project in File->Settings...->Project interpreter->(Gear icon)->Show all...:
Then delete and recreate the necessary entries. Or edit them and specify correct paths.
E.g. this is what my list looks like after I deleted an Anaconda installation:
Path in the virtualenv to its base installation
Since virtualenv is not a full installation, it must have a path to its base installation stored somewhere to be able to use files from there.
As of this writing, virtualenv (v16.0.0) in Windows is implemented like this:
The real python.exe and several other files are copied into the virtualenv's subtree
In Lib\orig-prefix.txt, the path to the base installation is stored. It is used to add the base installation's Lib to sys.path via a custom site.py.
So, if the path in that file becomes invalid, the virtualenv's Python interpreter will be unable to find any standard modules except those few that were copied. Which perfectly fits your symptoms.
I currently have the same issue, that I can't install any package tool in Pycharm and that freak me out. Here is the step I fixed it, just want to share. OuO.
Step 1
Find show all in the right corner of a setting icon
Step 2
Click the + icon to open Add python Interpreter
Step 3
In New environment 's Location Under Virtualenv Environment select file
Step 4
Find your Pycharm file and make an empty file under it and click OK and keep click OK
Step 5
Now in Project Interpreter select the empty file you just create and now you should be fine to install Pycharm package.Hope this solve your problem.
In my case the problem was because I was using WSL to host my project so the project address used by PyCharm to create and select the venv was wrong. Instead of using the option Virtualenv Environment to create the environment:
You need to select the WSL option from the side bar and then enter the path to your new or existing venv.
Nothing above worked for me
I made a simple change , Hope it works for you too !!
It happens due to conflict in storing python.exe , In my case it was in F:\ drive
Solution :- Pycharm expects python.exe file to be present in some location , you can check that in project interpreter , it will show some default location where pycharm is searching to execute exe file , but issue is the exe file is not present at that location , so create the folder which pycharm was expecting to execute exe file and paste the downloaded exe file
Hope it Works for you !!
Happy Coding
Well, i'm pritty new to Python, and I did too had a re-install of my os after a crash
Old setup:
In the old system setup I used python 3.7.4. I made al my (practice)projects with that, and each project had a venv/scripts/python3.7.exe in it.... my undertanding is/was that all the files in these virtual environment where 'stand alone', so sufficient to run a python 3.7.4 for that specific projec files, and not depending on files of the home-python-dir.
The install-directory of python was c:\Program Files (x86)\python 37-32
Each project had a file [project-path]/venv/pyvenv.cfg, and in this file there was the line
home = C:\Program Files (x86)\Python37-32
then - my system crashed - reinstalled windows 10, and downloaded again python, but this time python 3.8, and it installed in C:\Program Files (x86)\Python38-32
New setup:
So, after some hairs lost - I also installed the old python version 3.7.4 in the specific path stated in the pyenv.cfg file (C:\Program Files (x86)\Python37-32). So, i had 2 python versions installed on my new system, one in .../python38-32 and one in .../python37-32
And that worked, so when I selected in 'add interpreter/existing interpreter' and pointed to the [project]/venv/python3.7.exe it worked like a charm.
So, apearantly there are files in each version-specific home-directory that pycharm/python needs - i was under the impression that the files in the .venv directory would be all it needed....
I faced this issue when I switched my system which had different python version installed at different location. The simple short solution is to open 'pyenv' file and point it to the current installation path in your current system and that's it.
I had the same problem and couldn't really figure it out.
As it was a side project the mistake was infuriating and hilarious at the same time.
My folder names had non-english letters. Specifically it had the letter "đ" and the SDK was always invalid because of it.
You might say a stupid mistake, it was, but I wasn't really paying attention.
Hope this helps somebody.
I get the issue in Pycharm 2021.2.3 when I try to make a new environment using an exe that is called anything but python.exe (I was organising my different versions by calling them python39.exe, python38.exe, etc.). I just stopped doing that and renamed all my python exes to python.exe and it started working.
go to the Edit Configuration foe edit interpreter, then remove all interpreter then ok.
now, you should add new interpreter and select the path of python.exe in your installation path(for example c:\ ),then ok.
for me, i solved this error by this solution.
The paths specified in pyvenv.cfg need to be corrected after the venv folder is copied from one computer to another. The main place to look at is the user name. For example:
Old computer:C:\Users\OldComputerUserName\AppData\Local\Programs\Python\Python310
New computer:C:\Users\NewComputerUserName\AppData\Local\Programs\Python\Python310
The path is fixed when you add interpreter to the project the 1st time. I learned it the hard way too.
This problem is because the interpreter path points to the virtual-env, instantiated to the particular project. But we don't have any python installed there.
Therefore we have to set the interpreter path to the "python.exe" file inside the python folder which we have installed on our PC.
This can solve this problem very easily.
If you haven't installed python on your machine please install it and set the path accordingly.
Thank you.
I also had this issue and it's 2023! All I can tell you is what I did to fix it. I tried the other solutions listed in this post (at least the ones I looked at) and they didn't work.
What I did was I copied the venv file in my project (for safekeeping) and then moved it elsewhere.
I deleted the venv file in my project after making my backup and I deleted the interpreter that I had been trying to use.
From there I opened up File -> Settings -> Python Interpreter -> and since there was now no interpreter and no venv folder
I created the interpreter again. Make sure to list the proper path to the version of the python exe you want to use!
From there you pretty much just apply your changes and you will see it pop up with some prompts. It will create a new venv folder for you, just accept the prompts and it worked for me.
When I try to run my program from the PyCharm IDE everything works fine but if I type in Fedora:
python myScript.py
in a shell prompt I get an import error from 1 of the module.
ImportError : No modue named myDependency
What does PyCharm do that allows the interpreter to find my dependencies when launched from the IDE? How can I get my script to find its dependencies so it can be launched with a singe command?
There are a few possible things that can be causing this:
The same python interpreter? Check with import sys; print(sys.executable)
Is it the same working directory? Check with import os; print(os.getcwd())
Discrepancies in sys.path, which is the list python searches sequentially for import locations, can possibly caused by environment variables. Check with import sys; print(sys.path).
Adding this worked for me:
from os import sys, path
sys.path.append(path.dirname(path.dirname(path.abspath(__file__))))
As a first step, in PyCharm go to project settings / python interpreter, and note the path. Then compare that to the result of which python -- do they line up? If not, you need to make them do so.
If that's ok, check what PyCharm defines as your project root in project settings / project structure. Is that the directory where your script is located? If not, you should run the script from that directory or append the directory to the $PYTHONPATH variable.
Almost definitely, it's one of those two things.
You might have set some project dependency in Pycharm for module myDependency.
You can access the same in Fedora by importing the module explicitly or by creating the egg of that module and installing it.
This will then go to python site-packages from where you can refer this dependency.
