I installed miniconda on Windows 10 and created an environment (I followed this guide: https://www.notion.so/shashankkalanithi/Setting-Up-Conda-Environment-ba83f7f019ea44b9af37588eed419eb9). However when I open the VS Code I don't see that environment python interpeter on kernel list. There is only one interpreter on the list: ~\Miniconda3\python.exe
How can I fix this?
in vscode press ctrl+shift+p and type python:Select Interpreter you should see all the environment there. If it does not appear create a .py file and try again. also you can press the reload icon on the search bar where you typed python:select interpreter.
You can try to follow methods from
vscode - Create a conda environment
Additional notes:
...To ensure the environment is set up well from a shell perspective, one
option is to use an Anaconda prompt with the activated environment to
launch VS Code using the code . command. At that point you just need
to select the interpreter using the Command Palette or by clicking on
the status bar.
Firstly you need to create an environment with python in it otherwise it won't recognize it. Create an environment like this first
conda create --name tf26 python==3.10
Use your preferred name and python version here thereafter restart VS Code. You will definitely see your env.
Note:
You can delete any unused env if want like this
conda env remove --name <env_name>
I wanted to use the new environment as a Jupyter kernel and had to install the jupyter package for it to show up in the kernel selection of VSCode. You can install it by running conda install jupyter.
I finally resolved the problem.
This thread says that you need to create the conda environment passing the python argument:
conda create -n your_env_name python=3.7
Doing this the environment appears in the Select interpreter to start Jupyter server options.
The extension automatically looks for interpreters in the following locations:
Conda environments that contain a Python interpreter. VS Code does not
show conda environments that don't contain an interpreter.
After you create a conda environment, you need to activate it and install some packages in order to get the python interpreter. And remember to reload the VSCode. If it still does not exist, you can try to choose Enter interpreter path, to point the path manually.
In your project .vscode/settings.json file, just replace the old python.pythonPath setting with the new one (or add if non-existing) python.defaultInterpreterPath and it will work. The value for the setting is the path to the venv you're using in your project.
Afterward, Ctrl+Shift+P via Python: Select Interpreter will allow you to choose a different interpreter.
I had the same problem.
After I opened Anaconda Prompt as Administrator and created the environment, I saw it in VS code
Open “Anaconda Prompt” from the Windows start button as
“Administrator.”
The reason why vscode doesn't show the environment is that it doesn't have a python interpreter in it because of inheriting or something.
The solution is also simple. Just manually install python in that environment.
conda install python
I'm new using Jupyter on Miniconda and I was having a problem while importing packages (ImportError: DLL load failed ), looking for answers the solution was to initialize a base environment in my bash.
I used to initialize jupyter typing jupyter notebook in bash, but using the solution given, I have to activate conda activate bash and then type jupyter notebook. What is the difference between starting Jupyter the way I used to and this new way?
conda activate command activates a virtual environment. It is an isolated environment so all packages you installed in the virtual environment cannot be used outside it. When you start bash, you are in the base environment and it seems that you installed your Jupiter in bash environment so you cannot use bash's Jupiter in base environment and vice versa. It may be a little annoying at the beginning, but it can let you use different environments for different purposes. For example, since pip only allows one version of a specific package to be installed, different environments can let you test a new version of a package without breaking the functionality of the original program.
I've installed Anaconda and created two extra environments: py3k (which holds Python 3.3) and py34 (which holds Python 3.4). Besides those, I have a default environment named 'root' which the Anaconda installer created by default and which holds Python 2.7. This last one is the default, whenever I launch 'ipython' from the terminal it gives me version 2.7. In order to work with Python 3.4, I need to issue the commands (in the shell)
source activate py34
ipython
which change the default environment to Python 3.4. This works fine, but it's annoying since most of the time I work on Python 3.4, instead of Python 2.7 (which I hold for teaching purposes, it's a rather long story). Anyway, I'll like to know how to change the default environment to Python 3.4, bearing in mind that I don't want to reinstall everything from scratch.
If you just want to temporarily change to another environment, use
source activate environment-name
ETA: This may be deprecated. I believe the current correct command is:
source conda activate environment-name
(you can create environment-name with conda create)
To change permanently, there is no method except creating a startup script that runs the above code.
Typically it's best to just create new environments. However, if you really want to change the Python version in the default environment, you can do so as follows:
First, make sure you have the latest version of conda by running
conda update conda
Then run
conda install python=3.5
This will attempt to update all your packages in your root environment to Python 3 versions. If it is not possible (e.g., because some package is not built for Python 3.5), it will give you an error message indicating which package(s) caused the issue.
If you installed packages with pip, you'll have to reinstall them.
Overview
Some people have multiple Conda environments with different versions of Python for compatibility reasons. In this case, you should activate the desired default environment in the shell initialization file (e.g., .bashrc, .zshrc). With this method, you can preserve the versions of Python you use in your environments.
The following assumes environment_name is the name of your environment
Mac / Linux:
Edit your bash profile so that the last line is conda activate environment_name. In Mac OSX this is ~/.bash_profile, in other environments this may be ~/.bashrc
Example:
Here's how I did it on Mac OSX
Open Terminal and type:
nano ~/.bash_profile
Go to end of file and type the following, where "p3.5" is my environment:
conda activate p3.5
Exit File. Start a new terminal window.
Type the following to see what environment is active
conda info -e
The result shows that I'm using my p3.5 environment by default.
For Windows:
Create a command file (.cmd) with activate environment_name and follow these instructions to have it execute whenever you open a command prompt
Create a batch file command, e.g. "my_conda.cmd", put it in the Application Data folder.
Configure it to be started automatically whenever you open cmd. This setting is in Registry:
key: HKCU\SOFTWARE\Microsoft\Command Processor
value: AutoRun
type: REG_EXPAND_SZ
data: "%AppData%\my_conda.cmd"
from this answer: https://superuser.com/a/302553/143794
Under Linux there is an easier way to set the default environment by modifying ~/.bashrc or ~/.bash_profile
At the end you'll find something like
# added by Anaconda 2.1.0 installer
export PATH="~/anaconda/bin:$PATH"
Replace it with
# set python3 as default
export PATH="~/anaconda/envs/python3/bin:$PATH"
and thats all there is to it.
For windows Anaconda comes with Anaconda Prompt which is a shortcut to cmd and can be used run conda commands without adding anaconda in PATH variable.
Find the location of it, copy and rename the copy (say myenv_prompt). Right click myenv_prompt and select properties in the context menu.
The Target form of Properties window should already be filled with text, something like %windir%\system32\cmd.exe "/K" C:\Users\xxx\AppData\Local\Continuum\Miniconda3\Scripts\activate.bat C:\Users\xxx\AppData\Local\Continuum\Miniconda3\
There are three parts of this command 1)start ...\cmd.exe 2)run ...\acitvate.bat with environment 3)...\Miniconda3\
Change 3rd part to path of the environment (say myenv) you want as default i.e. fill the Target form something like %windir%\system32\cmd.exe "/K" C:\Users\xxx\AppData\Local\Continuum\Miniconda3\Scripts\activate.bat C:\Users\xxx\AppData\Local\Continuum\Miniconda3\envs\myenv
Now myenv_prompt will act as shortcut to start cmd with myenv as the default environment for python. This shortcut you can keep in start menu or pinned in taskbar.
One advantage of this method is that you can create a few shortcuts each having different environment as default environment. Also you can set the default folder by filling Start in form of the Properties window
Hope this helps
PS:It is not required to find Anaconda Prompt and can be done by changing target of any shortcut. But you will require to know path of cmd.exe and activate.bat
Just activate your py34 environment when you load your terminal/shell.
If you use Bash, put the line:
conda activate py34
in your .bash_profile (or .bashrc):
$ echo 'conda activate py34' >> ~/.bash_profile
Every time you run a new terminal, conda environment py34 will be loaded.
The correct answer (as of Dec 2018) is... you can't. Upgrading conda install python=3.6 may work, but it might not if you have packages that are necessary, but cannot be uninstalled.
Anaconda uses a default environment named base and you cannot create a new (e.g. python 3.6) environment with the same name. This is intentional. If you want your base Anaconda to be python 3.6, the right way to do this is to install Anaconda for python 3.6. As a package manager, the goal of Anaconda is to make different environments encapsulated, hence why you must source activate into them and why you can't just quietly switch the base package at will as this could lead to many issues on production systems.
Change permanent
conda install python={version}
Change Temporarily
View your environments
run conda info --envs on your terminal window or an Anconda Prompt
If It doesn't show environment that you want to install
run conda create -n py36 python=3.6 anaconda for python 3.6 change version as your prefer
Activating an environment (use Anaconda prompt)
run activate envnme envnme you can find by this commandconda info --envs as a example when you run conda info --envs it show
base * C:\Users\DulangaHeshan\Anaconda3
py36 C:\Users\DulangaHeshan\Anaconda3\envs\py36
then run activate py36
to check run python --version
In Windows, it is good practice to deactivate one environment before activating another.
https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html?highlight=deactivate%20environment
If you want Anaconda Navigator to default to Virtual Env you created, go to file > Preference and select default conda env in drop down lint:
If you want Anaconda command automatically opens to virtual env without having to type activate envName, do this:
Right click on conda shortcut > go to properties and change the Target to something like this:
%windir%\System32\cmd.exe "/K" C:\Anaconda\Scripts\activate.bat C:\Anaconda\envs\p37
Optionally you can set your default working dir as well, like I did in snapshop below:
gl
On Windows, create a batch file with the following line in it:
start cmd /k "C:\Anaconda3\Scripts\activate.bat C:\Anaconda3 & activate env"
The first path contained in quotes is the path to the activate.bat file in the Anaconda installation. The path on your system might be different. The name following the activate command of course should be your desired environment name.
Then run the batch file when you need to open an Anaconda prompt.
Here is the solution I found for autoactivating my preferred environment on a Windows 10 system:
Open anaconda prompt & use 'conda env list' to find the location of the environment you wish to use.
Go to the start menu, right-click 'Anaconda Prompt' and go to file location.
Create a copy of this shortcut file
Open its properties & change the target to the location of your preferred environment.
Now every time you open anaconda prompt through this shortcut it will automatically load your chosen environment.
activate.py is hardcoded to emit conda activate base\n into your shell profile when you evaluate the shell hook produced by conda shell.zsh hook.
you can suppress this hardcoded "auto-activate base" via:
conda config --set auto_activate_base false
then, in ~/.zshrc, ~/.bashrc or wherever you source your shell profile from, you can append the following (after the conda shell hook) to explicitly activate the environment of your choosing:
conda activate py34
I wasn't satisfied with any of the answers presented here, since activating an environment takes a few seconds on my platform (for whatever reason)
I modified my path variable so that the environment I want as default has priority over the actual default.
In my case I used the following commands to accomplish that for the environment "py35":
setx PATH "%userprofile%\Anaconda3\envs\py35\;%PATH%"
setx PATH "%userprofile%\Anaconda3\envs\py35\Scripts;%PATH%"
to find out where your environment is stored, activate it and enter where python.
I'm not sure yet if this approach has any downsides. Since it also changes the default path of the conda executable. If that should be the case, please comment.
For Jupyter and Windows users, you can change the Target path in your Jupyter Notebook (anaconda3) shortcut from C:\Users\<YourUserName>\anaconda3 to C:\Users\<YourUserName>\anaconda3\envs\<YourEnvironmentName>
you could do the same thing for the Anaconda Prompt..etc.
After changing the path you can check your active environment by opening a terminal in Jupyter and run conda info --envs.
I got this when installing a library using anaconda. My version went from Python 3.* to 2.7 and a lot of my stuff stopped working.
The best solution I found was to first see the most recent version available:
conda search python
Then update to the version you want:
conda install python=3.*.*
Source: http://chris35wills.github.io/conda_python_version/
Other helpful commands:
conda info
python --version
Create a shortcut of anaconda prompt onto desktop or taskbar, and then in the properties of that shortcut make sure u modify the last path in "Target:" to the path of ur environment:
C:\Users\BenBouali\Anaconda3\ WILL CHANGE INTO
C:\Users\BenBouali\Anaconda3\envs\tensorflow-gpu
preview
and this way u can use that shortcut to open a certain environment when clicking it, you can add it to ur path too and now you'll be able to run it from windows run box by just typing in the name of the shortcut.
Tried both source activate default_3_9 and source conda activate default_3_9
but worked conda activate default_3_9
I'm trying to update Anaconda in order to use Python 3.10.4 and then Spyder 5.3.2. Actually, I wanted to set the Python interpreter used by Pycharm inside the Spyder console but it required the newest Spyder version. I didn't try all the possible solutions (it's pending for me to use the window batch and modifying path solutions given here) but:
Since I couldn't update the Anaconda base due to the well-known error on the "Solving environment". Then Python and Spyder remain the same.
Creating a new env allows to get the last Python and then his newest Spyder version but it doesn't actualize the Anaconda shortcuts and even the Anaconda navigator if you set it to this new env still has some inconsistencies like keeping the older Spyder version in his menu.
Besides, on point 2, changing the shortcuts target path doesn't work for me.
Finally, I create a new shortcut of the Spyder file from the Scripts folder inside the environment directory ( C:\Users<userName>>\Anaconda3\envs<EnvName>\Scripts )
I couldn't use the default Anaconda shortcuts but I have what I wanted and quick access.
I am trying to change the Interpreter from Python 3.7 to Python 3.6 in Spyder. I have gone to preferences then to Python Interpreter. I click the drop down box but there is nothing there. How do I add Python 3.6 as on option in the drop down?
You are using Spyder then I assume you have installed Anaconda.
Unfortunately tensorflow doesnt work in python 3.7 yet.
To use Tensorflow/Keras: create new environment with python 3.6 and then use them seamlessly.
To create enviroment in conda:
Use anaconda prompt/anaconda navigator for environment management.
In case of Anaconda Prompt, create environments similar to below code
conda create --name env_name python=3.6
then to use this environment just created, do:
activate env_name # on windows
source activate env_name # on mac
Then if you are done with your works in that environment, deactivate the environment using deactivatecommand in prompt.
deactivate # in windows
source deactivate # in mac

I've looked at all the responses in the search and specifically Use Conda environment in pycharm without resolving my problem.
I'm on Win10 using the latest Anaconda and PyCharm for Python 3.6. The situation is that I've created a new environment using Conda which uses the Python version available in the base environment. Therefore, there is no python.exe in the newly created environment. In PyCharm, when I try to select the Conda environment, the dialog apparently does not see a Python there and refuses to set that as the environment.
In PyCharm, I create a new Project (pure Python) and set the location for the project in my PyCharmProjects directory. I then try to select existing interpreter and navigate to the appropriate Conda environment which I'm unable to select.
I'm not sure if there is something I don't understand or there is actually a problem here, but I'm getting a bit frustrated trying
to find the proper approach. Any help appreciated.
--Don
When you create the conda environment from cmd prompt do you explicitly tell it what python you want to use?
conda create --environmentName python=3.6
That should place a python.exe in your environment.
