Help support Spyder, the community-developed scientific IDE!

Thanks to your continuing support, we are on track for a Spyder 4 release in early 2019 with all of your most-requested features (a new debugger and completion architecture, better Projects, new Editor functionality, full Variable Explorer object support, a built-in dark theme and much more)!

Spyder development is made possible by contributions from our global user community, along with organizations like NumFOCUS and Quansight. There are numerous ways you can help, many of which don't require any programming. If you'd like to make a donation to help fund further improvements, we're on OpenCollective.

Thanks for all you do to make the Spyder project thrive! More details


Overview

Spyder is a powerful scientific environment written in Python, for Python, and designed by and for scientists, engineers and data analysts. It offers a unique combination of the advanced editing, analysis, debugging, and profiling functionality of a comprehensive development tool with the data exploration, interactive execution, deep inspection, and beautiful visualization capabilities of a scientific package.

Beyond its many built-in features, its abilities can be extended even further via its plugin system and API. Furthermore, Spyder can also be used as a PyQt5 extension library, allowing you to build upon its functionality and embed its components, such as the interactive console, in your own software.

For more general information about Spyder and to stay up to date on the latest Spyder news and information, please check out our new website.

Core components

  • Editor

    Work efficiently in a multi-language editor with a function/class browser, real-time code analysis tools (pyflakes, pylint, and pycodestyle), automatic code completion (jedi and rope), horizontal/vertical splitting, and go-to-definition.

  • Interactive console

    Harness the power of as many IPython consoles as you like with full workspace and debugging support, all within the flexibility of a full GUI interface. Instantly run your code by line, cell, or file, and render plots right inline with the output or in interactive windows.

  • Documentation viewer

    Render documentation in real-time with Sphinx for any class or function, whether external or user-created, from either the Editor or a Console.

  • Variable explorer

    Inspect any variables, functions or objects created during your session. Editing and interaction is supported with many common types, including numeric/strings/bools, Python lists/tuples/dictionaries, dates/timedeltas, Numpy arrays, Pandas index/series/dataframes, PIL/Pillow images, and more.

  • Development tools

    Examine your code with the static analyzer, trace its execution with the interactive debugger, and unleash its performance with the profiler. Keep things organized with project support and a built-in file explorer, and use find in files to search across entire projects with full regex support.

Documentation

You can read the Spyder documentation online on the Spyder Docs website.

Installation

For a detailed guide to installing Spyder, please refer to our installation instructions.

The easiest way to install Spyder on any of our supported platforms is to download it as part of the Anaconda distribution, and use the conda package and environment manager to keep it and your other packages installed and up to date.

If in doubt, you should always install Spyder via this method to avoid unexpected issues we are unable to help you with; it generally has the least likelihood of potential pitfalls for non-experts, and we may be able to provide limited assistance if you do run into trouble.

Other installation options exist, including:

  • The WinPython distribution for Windows
  • The MacPorts project for macOS
  • Your distribution's package manager (i.e. apt-get, yum, etc) on Linux
  • The pip package manager, included with most Python installations

However, we lack the resources to provide individual support for users who install via these methods, and they may be out of date or contain bugs outside our control, so we recommend the Anaconda version instead if you run into issues.

Troubleshooting

Before posting a report, please carefully read our Troubleshooting Guide and search the issue tracker for your error message and problem description, as the great majority of bugs are either duplicates, or can be fixed on the user side with a few easy steps. Thanks!

Running from a git clone

Please see the instructions in our Contributing guide to learn how to do run Spyder after cloning its repo from Github.

Dependencies

Important Note: Most or all of the dependencies listed below come with Anaconda and other scientific Python distributions, so you don't need to install them separately in those cases.

Build dependencies

When installing Spyder from its source package, the only requirement is to have a Python version equal or greater than 3.6.

Runtime dependencies

The basic dependencies to run Spyder are:

  • Python 3.6+: The core language Spyder is written in and for.
  • PyQt5 5.6+: Python bindings for Qt, used for Spyder's GUI.

The rest our dependencies (both required and optional) are declared in this file.

  • Very slow line execution using IPython in macOS

    Very slow line execution using IPython in macOS

    After running a few initial commands in a new IPython console (regardless of what they may be), line execution automatically defaults to multline mode and slows down considerably. For example:

    Opening new IPython console:
    Python 3.5.1 (default, Dec 20 2015, 15:56:10) 
    Type "copyright", "credits" or "license" for more information.
    
    IPython 4.0.1 -- An enhanced Interactive Python.
    ?         -> Introduction and overview of IPython's features.
    %quickref -> Quick reference.
    help      -> Python's own help system.
    object?   -> Details about 'object', use 'object??' for extra details.
    %guiref   -> A brief reference about the graphical user interface.
    
    In[1]: l1 = ['apple','orange','banana']
    In[2]: l2 = ['carrot','onion','zucchini']
    In[3]: l3 = ['yellow','green','red']
    In[4]: l4 = ['Honda','Toyota','Ford']
      ...:
    

    This last line will take several seconds to execute, and all subsequently entered statements will behave similarly, making the console virtually unusable.

  • Clean conda Windows install, followed by 'conda update --all' results in wrong mkl dlls being used for Spyder

    Clean conda Windows install, followed by 'conda update --all' results in wrong mkl dlls being used for Spyder

    Problem Description

    A clean conda install from https://www.anaconda.com/download/#windows (version 5.2.0) works for Spyder, but if I then do a 'conda update --all', the resulting configuration is broken. When you run Spyder, launching from Anaconda navigator, you get a message about a missing ordinal 242 in Anaconda3\Library\bin\mkl_intel_thread.dll

    This turns out to be because the dlls from mkl-2018.0.3-1 are installed in Anaconda3\Library\bin, but something in Spyder needs the dlls from mkl-2018.0.2-1 instead. If you copy the dlls from Anaconda3\pkgs\mkl-2018.0.2-1\Library\bin into Anaconda3\Library\bin, Spyder then launches normally. (This probably breaks something else, but if so, it's something I haven't yet tried to use ;-)

    What steps reproduce the problem?

    1. Install Anaconda for Windows
    2. run conda update --all
    3. Launch Spyder

    What is the expected output? What do you see instead?

    Augment or replace rope with Jedi

    From [email protected] on 2012-12-30T15:26:39Z

    In the Jedi bookmark of https://code.google.com/r/stevensilvester-rich-text-to-thread/source/browse , I have replaced rope with Jedi.

    What Jedi offers is an excellent recursiveness that makes it possible to tease out the proper object from very complex code.

    Jedi appears to be about as fast as rope, unless you are parsing against a large library for the first time that session. I have engaged with the author of Jedi on how to overcome this. Also, some objects with dynamic docstrings will not show the same docstring as the rope version, such as functools.partial.

    Prior to making the speed improvements, perhaps we can default to rope, and lean on Jedi when rope fails to find the object?

    I am using a clone of the main development repo on Ubuntu 12.04, 32bit.
