VS Code and Jupyter notebook problems with the python interpreter - python

Im currently doing a project in VS Code using Jupyter Notebook, however I have some problems with the python interpreter. The problem seem to do with VS Code using two different interpreters.
I have chosen, what I think is the right interpreter, in the upper right corner, namely
However, when I check what version of Python is used in the terminal, then my version is 2.7.17, whereas it should be 3.8.5. I have already tried restarting the kernal, VS Code and changed between other interpreters. I dont know if it has something to do with the Julia env. as shown below:
Can anybody help me understand the problem, and maybe a fix?

The vscode integrated terminal uses the built-in powershell or cmd of windows. If you type python in the terminal, it will open the interactive terminal of the python version pointed to by the system environment variable. What you choose in the upper right corner of jupyter is just the jupyter notebook kernel, not even the python interpreter for vscode.
Ctrl+Shift+P to open the command palette, search for and select Python:Select Interpreter, then select the interpreter for the python file.
Of course, this operation is only valid for vscode. If you want the terminal to also use the interpreter you selected for vscoe in the Select Interpreter panel, use a virtual environment. When you activate the virtual environment in the vscode terminal, typing python will open the python interactive terminal under the environment.

Use Visual Studio Code with Miniconda on macOS

On my Mac, I installed Python using Miniconda and I have also installed various Python packages using conda. In the Mac Terminal app, my base conda environment is active and when I run Python it correctly uses the Miniconda version of Python as shown below:
In Visual Studio Code (VSCode), I have selected the Miniconda version of Python using the Python Interpreter setting. The correct version of Python and conda environment is shown at the bottom of the window:
However, when I use the built-in terminal in VSCode it still uses the macOS Python even though it shows the base conda environment is active:
I'm using the Python, One Dark Pro, and Jupyter extensions in VSCode. Also, the $PATH in the VSCode terminal and in the Mac terminal app returns the following:
# VSCode terminal
base ❯ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin:/Library/Apple/usr/bin:/Users/gavinw/miniconda3/bin:/Users/gavinw/miniconda3/condabin
# Mac terminal app
base ❯ echo $PATH
/Users/gavinw/miniconda3/bin:/Users/gavinw/miniconda3/condabin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin:/Library/Apple/usr/bin
How can I configure the Visual Studio Code terminal to use the Miniconda version of Python?
After selecting the Python that comes with conda, the Python interpreter will be displayed in the lower left corner of VSCode, and then use the shortcut key Ctrl+Shift+` to open a new VSCode terminal, (or click "Terminal", "New terminal") it will automatically enter the selected environment and activate it automatically.
The terminal uses whatever python environment your configured shell command is set to. It is in no way linked to the environment of VS Code
However, If you attempt to run a Python file, it will open up the terminal with the full path to the specified interpreter
These details are laid out in the docs
The Python extension uses the selected environment for running Python code (using the Python: Run Python File in Terminal command), providing language services (auto-complete, syntax checking, linting, formatting, etc.) when you have a .py file open in the editor, and opening a terminal with the Terminal: Create New Integrated Terminal command. In the latter case, VS Code automatically activated the selected environment.
Also, if using code command from an activated session...
launching VS Code from a shell in which a certain Python environment is activated does not automatically activate that environment in the default Integrated Terminal.
Otherwise, launching the desktop app directly would also not be done from an activated conda environment
You may want to check the value in your settings for "python.terminal.activateEnvironment", but I believe this only applies when you actually run a .py file

VS Code does not change python environment

I am using VS-Code and anaconda environment for python interpreter. I select the exact anaconda base environment by ctrl + shift + ` and it also reflects in the downside panel of vscode. But, when I checked the python version it shows my system's default python environment 3.7.9. If you see the below screenshot than, the anaconda environment is with 3.8.3.
Please give me solution, Thank you.
Changing the version in VSCode does not change the the instance that your PS instance will use. Try doing where python to see where the V3.7.9 that your PS instance is picking up is. Then remove that version from the environment variables and add the path to the V3.8.3 instead.
Additionally you can do: To forcefully use v3.8.3
Specify python version in command
py -3.8 <command>
OR set PY_PYTHON environment variable to set which version to use.
Take a look at this for further help Python docs
after changing the environment, you can restart the vs code again. it might be changed now. if not, then try changing now againg by clicking the interpreter name which is displayed on left bottom of the vscode window
For those tried these steps and achieved nothing:
select different interpreter
reboot VScode
reinstall VScode Python extension and delete its folders
Probably you are working in the workspace and not in folder. You probably set interpreter at workspace level, that can't be used in one of the folders of the workspace. Try to open your folder separately from the workspace and select interpreter you want. This worked for me.
To check & change vs code interpreter:
In top left menu bar Click view
In the dropdown menu, Click Command Palette
Click Python: Select Interpreter
Choose & Click on your desired Interpreter
Another way to be sure to use anconda interpreter, open anaconda navigator and launch vs code from there.

Arrow up / previous command in VSCode Python Interactive not working

I'm working with VSCode on an Ubuntu 18.04 machine. Everything is fine except that I can't get back to the previous command in Python Interactive Window via Arrow Up. It works in the integrated terminal though, integrated shell is /bin/bash.
I have no idea where this is coming from. I changed "keyboard.dispatch" to "keyCode", but that's not the problem. I also tried different versions of the python-extension.
Do you have any idea?
Thanks!
Not sure if this is helpful for you as an Ubuntu user, but I came across the same problem in Windows this week. In my case, the issue cropped up after I installed the Python extension in VS Code (or at least I didn't notice the issue before this). The combination of using the Python extension, Git Bash for terminal, and python virtual environment killed the up arrow feature for me. Using python outside a virtual environment works fine. My solution was to use Command Prompt as the terminal when I wanted to use a virtual environment interactively.
In my situation, although I delete all the shortcuts of UpArrow, I still can get the previous command through UpArrow in Python interactive. This means there's no way to configure this shortcut, it was built in the plugin which built in Python extension.
So it's some problem with your Python extension, but you said you have tried to install a different version of Python extension but still not work. Make sure you have deleted it completely -> delete the extension folder manually(it's under C:\Users[UserName].vscode\extensions\ms-python.python-xxx).

VS Code: Can't load anaconda environment on Python Interactive

I am using VS Code in Windows 10.
I am able to use the dependencies in my conda environment if I Run the Python Script in Terminal. However, I am not able to use the environment in the Python Interactive shell.
For instance, I am using my datascienceenvironment which has the package fuzzywuzzy. I have included the env path into the settings.jsonas the python.pythonPath. But the Python version used in the Jupyter Notebook is the default anaconda base C:\\ProgramData\\Anaconda3\\python.exe
What is also extrange, is that if I run !conda list within the Notebook, I can see the fuzzywuzzy package.
What am I missing?
Thanks!
I'm a developer on the Interactive Windows. Priyatham has already pointed you in the right direction. Currently our Window tries to use the currently selected environment (the one in the lower left corner). But we didn't want to totally block customers if they didn't have Jupyter installed in each environment. So if the selected interpreter doesn't have Jupyter in the environment we'll check other environments on the system, looking for the closest python version match to the currently selected one. If we find something with Jupyter we'll launch the Interactive Window using that. In this case we do show a popup in the lower right indicating that we didn't find Jupyter and that we are falling back on a different environment, but this message can be pretty easy to miss.

How do you change environment of Python Interactive on Vscode?

I recently migrated from Spyder to VScode. I created a new conda environment and used setting.json to change the environment in VScode, "python.pythonPath": "/Users/dcai/anaconda3/envs/alphalens/bin/python"
However when I tried to run the code in Python Interactive, a different environment was loaded.
Is there a way for me to change the Python Interactive environment and match it to my terminal environment?
The Python Interactive window should be starting up using the Python version selected in the lower left corner of the VS Code IDE. This is the same environment that you can also pick via the Python: Select Interpreter command palette option. However the Python Interactive window does do one thing differently here. If the currently selected environment does not have jupyter installed it will look in the other environments for one that does and launch it, you should see a warning message in this case that a different environment was used.
Did this help answer your question? I'm a developer on this feature so I can help you debug if you are still seeing the wrong env launched.
I had the same situation as the OP. After reviewing #IanHuff's answer, that if desired (target) environment does not have Jupyter installed, the Python Interactive window will use another where it is found. I considered installing Jupyter in my target environment, but it would have installed a lot of packages. Having to do that for each virtual environment would be unnecessarily burdensome. So instead of the entire Jupyter package, I installed just the ipython_kernel in the target environment as follows and it worked:
$ ipython kernel install --user --name=<target_environment_name>
Hope this helps others trying to use Visual Studio Code with Jupyter Notebooks.
