Despite im used to program stuff, im new in Python so i decide to learn by myself.
So, i install VS code and python. At the moment i tryied to use stuff like tensorflow, is showing an error saying that my imports are missing.
I've already tryed to install everything again, search for a solution online and nothing worked.
If someone knows anything about how to fix this i'd be greatfull.
Whether there are multiple versions of python in your environment, which will make the pip installed in one version of python instead of the python you are using.
Use shortcuts "Ctrl+shift+P" and type "Python: Select Interpreter" to choose the correct python. Then use pip install packagename to reinstall the package which you need.
Generally, we recommend people new to python to use the conda virtual environment.
Confirm you have downloaded python correctly:
Open terminal
Run python --version
(if that doesn't work try python3 --version

I have used widely used packages(installed via pip) for a while in Jupyter notebook without any issues. I tried to do Python coding in VScode,but it somehow cannot load those packages.
I have tried changing python interpreter, but it did solve the issue. Does anyone know how to resolve this issue?
First make sure that you have the python interpreter installed on your computer. In your vscode UI you should see a terminal. You can install and upgrade pip through there if needed by using these commands:
pip install --upgrade pip
From here you should be able to import using pip commands.
Hi you can use terminal for installation.
otherwise you can anaconda iDE its very good tool and user friendly.
I've tried so many ways to fix this problem, like I've uninstall every python version I've downloaded and reinstall python 3.10.1(Although it show me that it was 3.9.10 when I check it by windows 11 cmd but VScode show me that it was 3.10.1. I have no idea that which I should trust). And I've also tried to install the module again and again(It said I've already install it). Also I can see the module was in my computer, which mean I can see it in the file. What's wrong??? If you know what's happened and you know how to fix it, please tell me! I need your suggestion to fix this stupid problem. Thanks!
It looks like you have multiple python environments and which environment you have installed the python modules was not which you have selected in the VSCode.
In the cmd execute where python to check all the python environments you have installed. In the VSCode click the python interpreter at the bottom-left on the VSCode to switch the python interpreter.
I have many different versions of Python, but a version that I use and that terminal show me if use command Python – version is 3.10.0.
When I use command pip list I got a big list of library, including the one I recently installed odfpy.
I open VsCode, choose Python version 3.10.0 and try to import odf but...
ModuleNotFoundError: No module named 'odf'
For sure I need to set something on VsCode or change some configuration in Linux but I cannot find a normal explanation of how to solve this issue.
If I change the Python version in VsCode with 3.8.10, odfpy (and also Django just installed) is recognized. So I suppose that, even if the Python version selected on the terminal is 3.10.0, when I pip install something, is installed on version 3.8.10. How do you manage this?
Please check which pip you are using through the command of pip --version.
After you switch the python interpreter in the VSCode, please create a new terminal, and make sure it has activated the environment you have selected.
I also use VS code and use Python 3.10 and i had try to download the odfpy which has gone alright, i use the command python -m pip install odfpy
try and see if it work for you though.
If it does not work, maybe try and create a virtual environment if you haven't created it yet.
In my case i was getting same error while using import-export django module. Installing odf library didn't worked got same error. I resolve this issue by simply pip install tablib==0.14.0.
I am installing python on windows10 and trying to install the opencv and numpy extentions in the command window. I get no error installing them and it says it is successfully installed. But when I try to check the installation and import cv2 it does not recognize it and give me the error: no module named cv2.
can anybody help me with this problem? Is there something wrong in installation process or do I need to install something else?
I checked the newest version of each and used the compatible one with my system.
Thanks.
One solution could be that you have 2 versions of python. So, go to the specific python's scripts directory and run: pip install numpy
If that too doesn't work, you can find the answers to this question on Why can't I import opencv3 even though the package is installed?, as stated by #Cut7er.
I have tried the solutions given to the above stated question myself also. But, they didn't work for me. So, another thing that you could try to use is this IDE called PyCharm. It ofcourse is much more beautiful that the IDLE, but it also has an inbuilt GUI controlled installation of binaries or packages. That would make things a lot easier. I have faced a lot of issues with packages for python and this IDE made things a lot easier. You can find it on https://www.jetbrains.com/pycharm/download/#section=windows.
You can also use anaconda. But, I found it a little difficult to use since, it has similar issues.
EDIT:
Seems like you are using PyCharm. But, you are installing libraries from your command prompt. So, see the answer to: ImportError: No module named 'bottle' - PyCharm. This answer guides you through how to install a certain library through your PyCharm window itself. So,
1) Go to Files>Settings
2) Search for "Interpreter" from the searching tab. Open the interpreter
3) You can now see a plus sign on the right. A click on it will open up a section on the left.
4) In the searching tab, search for numpy or opencv. Click on whichever module you want to install. And then click on the "install package" button on the bottom left. This will install the package for you.
5) Then click save. And run your file that says import cv/cv2.
This should probably do the trick.
Hope it helps!
Is it possible that you have 2 versions of python on your machine and your native pip is pointing to the other one? (e.g. you pip install opencv which installs opencv for python 2, but you are using python 3). If this is so, then use pip3 install opencv
I removed the Anaconda version on my machine, so I just have python 3.7 installed. I removed the python interpreter(Pycharm) and installed it again and the problem got fixed somehow!
I suspect you have two versions of python and the one you're using doesn't have opencv on it, because pip pointed to the wrong one.
A pragmatic solution assuming you're using the python version with conda is to just use conda to install cv2:
conda install -c menpo opencv
A more careful solution is to figure out how to get the pip that points to the python version you're using. On linux I can check that my pip points to my python like this:
:~$ which python
/home/kpierce/anaconda3/bin/python
:~$ which pip
/home/kpierce/anaconda3/bin/pip
So you see the pip and python versions are associated. On windows I suspect you do an analogous thing on the command line like
where python
where pip
And if they don't match, you might try
where python
where pip3
to see if those match. You need to use the pip that points to the correct python version. You can view the python version by entering the python interpreter and running
import sys
sys.version
I'm pretty new to programming, and very new to doing so in a UNIX environment, so please bear with me.
When I run
import sys
sys.executable
in my Python 3 console, the output is
usr\bin\python3
and I'm able to import whatever libraries I've installed with pip3, no problem.
When I do so in my Jupyter Notebook running a Python 3 kernel, the output is
usr\bin\python
and the libraries that I've installed with pip3 are inaccessible to me. What can I do to fix it so Jupyter is executing Python from the right place so I can use anything I've installed for Python 3 with pip3?
Thank you!
Short
You need to register your Python kernel with Jupyter, for it to find the "right" Python
Long
Jupyter is meant to work with multiple kernels, and languages; it is common for some users to have tens of kernels, many can be the same language, with small differences. You usually need to "tell" jupyter about these kernels, it is often referred to as "Installing a kernelspec". In your case you need to:
Install IPython & ipykernel for your Python 3
Using the ipykernel you just installed: install the kernelspec.
You'll find instruction on above link, a few tip though:
You can always safely replace python by /full/path/to/python if you are unsure.
when using pip, you can always replace pip (or pip3) by /full/path/to/python -m pip to use the pip linked to the python you want.
If you are tempted to use sudo, don't. People telling you to use sudo get issues after a few month when their linux distribution need to be updated – unless you really know what you're doing.
Once you've registered the Python kernel with Jupyter, it should just appear in the menus. You may need to refresh your browser though.
Enjoy !
