Configure a Python interpreter

To work with your Python code in PyCharm, you need to configure at least one Python interpreter. You can use a system interpreter that is available with your Python installation. You can also create a Virtualenv, pipenv, Poetry, or conda virtual environment . A virtual environment consists of a base interpreter and the installed packages.

With PyCharm Professional , you can also configure interpreters to execute your Python code on remote environments by using SSH, Vagrant, Docker, Docker Compose, or WSL (only for Windows).

When you configure a Python interpreter , you need to specify the path to the Python executable in your system. So, before configuring a Python interpreter, you need to ensure that you’ve downloaded Python and installed it in your system and you’re aware of a path to it.

You can create several Python interpreters based on the same Python executable. This is helpful when you need to create different virtual environments for developing different types of applications. For example, you can create one virtual environment based on Python 3.6 to develop Django applications and another virtual environment based on the same Python 3.6 to work with scientific libraries.

Python interpreters can be configured for a new project or for the current project (you can create a new interpreter or use one of the existing interpreters).

Configuring an existing Python interpreter

At any time, you can switch the Python interpreter either by using the Python Interpreter selector or in Settings .

Switch the Python interpreter using the Python Interpreter selector

Project interpreter selector

  • The Python Interpreter selector is located on the status bar. It is the most convenient and quickest way to switch the Python interpreter. Just click it and select the target interpreter:

Switch the Python interpreter in the IDE settings

View interpreters

  1. Press Control+Alt+S to open the IDE settings and then select Project | Python Interpreter .
  2. Click the drop-down and select the desired Python interpreter:
  3. If it’s not on the list, click Show All . Then select the desired interpreter in the left pane and click OK . When PyCharm stops supporting any of the outdated Python versions, the corresponding Python interpreter is marked as unsupported.

When you change the project interpreter and select an SSH interpreter, you might need to synchronize the local content with the target server. Mind a notification balloon in the lower-right corner:

Sync local files with the deployment server

You can choose to enable the automatic uploading of files to the server:

  • Click Auto-upload files to start uploading on the next save.
  • Click Sync and auto-upload files to immediately sync the files and upload them on every save in future.

Modify a Python interpreter

  1. Press Control+Alt+S to open the IDE settings and then select Project | Python Interpreter .
  2. Expand the list of the available interpreters and click Show All . Show all available interpreters

To configure a local Python interpreter for the current project, follow one of the procedures below:

Configure a system interpreter

  1. Ensure that you have downloaded and installed Python on your computer. Installing Python on Windows from Microsoft Store If you are on Windows, you can download Python from the Microsoft Store and install it as a Python interpreter. Once the Python application is downloaded from the Microsoft Store, it becomes available in the list of the Python executables. Note that interpreters added from the Microsoft Store installations come with some limitations. Because of restrictions on Microsoft Store apps, Python scripts may not have full write access to shared locations such as TEMP and the registry.
  2. Do one of the following:
    • Click the Python Interpreter selector and choose Add New Interpreter .
    • Press Control+Alt+S to open Settings and go to Project: | Python Interpreter . Click the Add Interpreter link next to the list of the available interpreters.

    • If the desired interpreter is not on the list, click , and then browse for the desired Python executable (for example, venv/bin/python on macOS or venv\Scripts\python.exe on Windows).

The selected virtual environment will be reused for the current project.

If PyCharm displays the Invalid environment warning, it means that the specified Python binary cannot be found in the file system, or the Python version is not supported. Check the Python path and install a new version, if needed.

Create a conda environment

New Conda environment

  1. Ensure that Anaconda or Miniconda is downloaded and installed on your computer, and you’re aware of a path to its executable file. For more information, refer to the installation instructions.

  • Select Existing environment . Then expand the Interpreter list and choose the desired interpreter.
  • If the desired interpreter is not on the list, click, and then browse for the Python executable within the previously configured Poetry environment.

The selected Poetry environment will be reused for the current project.

Configuring remote Python interpreters

When a remote Python interpreter is added, at first the PyCharm helpers are copied to the remote host. PyCharm helpers are needed to run remotely the packaging tasks, debugger, tests and other PyCharm features.

Next, the skeletons for binary libraries are generated and copied locally. Also, all the Python library sources are collected from the Python paths on a remote host and copied locally along with the generated skeletons. Storing skeletons and all Python library sources locally is required for resolve and completion to work correctly.

PyCharm checks the remote helpers version on every remote run, so if you update your PyCharm version, the new helpers will be uploaded automatically, and you don’t need to recreate remote interpreter.

Configure a WSL interpreter

  1. Do one of the following:
    • Click the Python Interpreter selector and choose Add New Interpreter .
    • Press Control+Alt+S to open Settings and go to Project: | Python Interpreter . Click the Add Interpreter link next to the list of the available interpreters.

New WSL interpreterFor a system interpreter, just provide the path to the Python executable in the selected Linux distribution. For virtual and conda environments, you can provide a path to a Python executable of an existing environment in the selected Linux distribution or create a new environment based on the specified Python.

Once done, the new interpreter will be added to your project, and the default mnt mappings will be set.

Configure an interpreter using Vagrant

  1. Ensure that the following prerequisites are met (outside of PyCharm):
    • One of supported Vagrant providers is installed on your computer.
    • Vagrant is installed on your computer, and all the necessary infrastructure is created.
    • The parent folders of the following executable files have been added to the system PATH variable:
      • vagrant.bat or vagrant from your Vagrant installation. This should be done automatically by the installer.
      • VBoxManage.exe or VBoxManage from your Oracle’s VirtualBox installation.
    • The required virtual boxes are created.
  2. Make sure that the Vagrant plugin is enabled.
  3. Ensure that you have properly initiated and started Vagrant. Basically, you need to open the Terminal window and execute the following commands:

You will not be able to use volumes and bind mounts for directories outside of the mapped local path. This table is not available on a Linux host, where Docker runs natively and you can mount any directory to the container.
    4. The following actions depend on whether you want to pull a pre-built image from a Docker registry or to build an image locally from a Dockerfile. Pull a Docker image Select Pull or use existing and specify the tag of the desired image in the Image tag field. Creating a Docker interpreter by pulling an imageBuild a Docker image Select Build and change the default values in the Dockerfile and Context folder fields if necessary. Creating a Docker interpreter by building an imageIf required, expand the Optional section and specify the following:
    Image tag Specify an optional name and tag for the built image. This can be helpful for referring to the image in the future. If you leave the field blank, the image will have only a random unique identifier.
    Build options Set supported docker build options. For example, you can specify metadata for the built image with the —label option.
    Build args Specify the values for build-time variables that can be accessed like regular environment variables during the build process but do not persist in the intermediate or final images. This is similar to using the —build-args option with the docker build command. These variables must be defined in the Dockerfile with the ARG instruction. For example, you can define a variable for the version of the base image that you are going to use:

    ARG PY_VERSION=latest FROM python:$PY_VERSION

    The PY_VERSION variable in this case will default to latest and the Dockerfile will produce an image with the latest available version of Python, unless you redefine it as a build-time argument. If you set, PY_VERSION=3.10 , Docker will pull python:3.10 instead, which will run a container with Python version 3.10. Redefining the PY_VERSION argument is similar to setting the following command-line option:

    —build-arg PY_VERSION=3.10

  • Wait for PyCharm to connect to the Docker daemon and complete the container introspection. Docker container introspection is completed

    Managing interpreter packages

    For each interpreter, you can install, upgrade, and delete Python packages. By default, PyCharm uses pip to manage project packages. For conda environments you can use the conda package manager.

    Managing packages

    PyCharm smartly tracks the status of packages and recognizes outdated versions by showing the number of the currently installed package version (column Version ), and the latest available version (column Latest version ). When a newer version of a package is detected, PyCharm marks it with the arrow sign and suggests to upgrade it.

    By default, the Latest version column shows only stable versions of the packages. If you want to extend the scope of the latest available versions to any pre-release versions (such as beta or release candidate ), click Show early releases .

    You can upgrade several packages at once. Hold Cmd (macOS) or Ctrl on (Unix or Windows), left-click to select several items in the list of packages, and then click Upgrade .

    See the detailed instructions:

    • How to install a package
    • How to upgrade the package
    • How to uninstall the package

    If you are looking for a more convenient way to search for Python packages, preview the documentation, and manage Python package repositories, try the Python Packages tool window. For more information, refer to Manage packages in the Python Packages tool window.

    «Error: Please select a valid Python interpreter» in Pycharm

    I have been asked to use Python in Pycharm and, after downloading it, I have found a problem which doesn’t allow me to compile anything because there is an «Error: Please select a valid Python interpreter» . I know there are similar questions already solved that propose solutions to this problem but I have revised those solutions and none of them is satisfactory for me. I would appreciate help very much. I let you here also some screenshots that show the error:

    Подключить интерпретатор

    Здравствуйте.
    Впервые в жизни решил познакомиться с Python. Немного погуглив понял, что в своей Ubuntu я могу без особых проблем писать код прям в стандартном текстовом редакторе, что я и делал. Работает, файлы исполняются. Но так как стандартный текстовый редактор несколько ограничен, то стал выбирать себе IDE. Выбор пал на PyCharm. Поставил, включил, создал проект, добавил Python файл и получил «No Python interpreter configured for the project». Ну т.е. интерпретатор она не видит. Нашёл в настройках где его задавать, а список пуст. Не понимаю как это так. Я ведь успешно исполняю написанное в текстовом редакторе. Если написать в терминале «python3 —version», то в ответ будет «Python 3.7.5». Ну т.е. он есть.
    Как сделать так, чтобы PyCharm его увидела? Если я что-то очень сильно не так понял, пожалуйста, объясните.

    Когда интерпретатор не добавлен, выглядит всё примерно так:

    Вы должны нажать Ctrl+Alt+S для вызова настроек. В настройках необходимо выбрать слева Project Interpreter, далее справа от строки с таким же названием Project Interpreter нажать на шестеренку и выбрать Add

    Откроется окошко в котором нужно нажать ОК(если как вы говорите в консоли питон работает, значит Pycharm должен подхватить интерпретатор сам)

    Далее тоже ОК

    Спустя несколько секунд в правой нижней части увидите версию интерпретатора, можно работать

    [Solved] No python interpreter configured for the project

    No python interpreter configured for the project is a common error message you may encounter in PyCharm. PyCharm is a very useful editor having nice features like debugging, testing, refactoring and code completion. However, it needs an external interpreter (Python.exe) to run Python code.

    This message tells you that project configuration should be updated to use a valid Python installation. To open the related configuration, you can click on Configure Python interpreter link as shown below. Or alternatively, you can select File -> Settings from the menu and open Project -> Python Interpreter setting.

    Python Interpreter setting shows that is selected for the project. To select (or create) a Python.exe interpreter click on Gear icon and select Show All… option.

    In the Python Interpreters window that opens, the list is empty. To add a new Python Interpreter click on Plus (+) icon.

    In Add Python Interpreter window, you can create a new virtual Python environment. My project is under C:\abcstudyguide\python directory, so I have created a folder venv under this directory to create a new virtual environment for my project.

    You must then choose a Base interpreter. Base interpreter is the python.exe file installed on your system. When you create a virtual environment, it will be based on Python version specified here. If you need a specific version of Python (like 3.8, 3.7), you need show path of this Python version in Base interpreter filed.

    If you don’t have Python installed on your system yet, you can download it from https://www.python.org/downloads/. Note that I installed Python in C:\Python\Python39 directory on my computer. However, default installation path is C:\Users\\AppData\Local\Programs\Python .

    Virtual Environments in Python
    Instead of creating a new virtual environment, you can also use the System Interpreter, but this method is not recommended.

    You can work on many different Python projects. Virtual environments are useful for creating an isolated environment for each Python project. Consider you are working on two different projects (ProjectA and ProjectB). Both projects are using the same library (LibraryX) but they require different versions of LibraryX. ProjectA needs version 1.0 of LibraryX, ProjectB needs version 2.0.

    To avoid version conflicts between third party libraries, each project should create and use its own virtual environment instead of using System Interpreter ( C:\Python\Python39\python.exe ).

    When you create a new Python virtual environment and select it as Python Interpreter in your project settings, No python interpreter configured for the project message will be gone.
