By default Spyder uses Python 2.7.2, and my question is: is there a way to set up Spyder so that it automatically uses Python 3.x? Thanks!

Since end of May 2013, version v2.3.0dev1 of Spyder works for Python 3.3 and above.
It is in a usable state but there are a few minor problems. Hopefully they will be resolved soon.

    This worked for me on Ubuntu 13.10. From their [download page](https://bitbucket.org/spyder-ide/spyderlib/downloads), I installed v2.3.0beta3.zip (which was the latest as of 8 Feb, 2014. I unzipped it, opened the folder and ran `python3 setup.py install`. I also had to do `sudo apt-get install python3-pyqt4` before running Spyder. – Garrett Feb 09 '14 at 02:38
  • Upgrading from Ubuntu 13.10 to 14.04 caused it to stop working. So I followed my previous comment and it now works on 14.04 also. – Garrett May 02 '14 at 05:20
  • BTW, if you have `checkinstall` (sudo apt-get install checkinstall), then it's better to do `sudo checkinstall python3 setup.py install`, because then you can easily remove it with `dpkg -r spyder`. – Garrett May 02 '14 at 05:21

To use Spyder for Python 3, you just need v2.3.0 or later.

Ubuntu 12.10 and later

You can get this by using pip3.

sudo apt-get install python3-pip python3-pyqt4
sudo pip3 install spyder

Ubuntu 12.04

Ubuntu 12.04 doesn't have python3-pip in the repositories, but you can get it with setuptools,

sudo apt-get install python3-pyqt4 python3-setuptools
sudo easy_install3 pip
sudo pip3 install spyder

you can then open Spyder from the launcher (after logging out and in) or from the terminal by typing spyder3.

Garrett's solution did not work for me. Pip is installed, but running the "install spyder" command does not install spyder using Python3.5. I uninstalled spyder.

What worked was simply:

sudo apt-get install spyder3

This will also automatically install any Python 3.x dependencies.

  • I just tried installing this. Installation worked, but I can't successfully run it. I get an error "The application Spyder3 has closed unexpectedly" – Selah Jan 23 '17 at 20:20
  • I assume python is installed? Sounds like an unrelated problem. – marts Jan 23 '17 at 20:22
  • python and python3 are indeed installed. Do you have any other advice? I suppose I will file a bug report. – Selah Jan 23 '17 at 20:25
  • Yeah I definitely did lots of googling. I had better luck with pip3 install spyder. – Selah Jan 23 '17 at 20:53

At the time this question was asked, Python 3 was not supported by Spyder (and this answer said so, giving some details of the then-incomplete porting efforts).

But that's not the case any longer! Recent builds of Spyder should work with Python 3. Check out the other answers for some links to places to get it from (though they may be out of date themselves by this point).

Another alternative: Use Anaconda to manage your scientific software.
There is an installer specifically for Python 3.5 https://www.continuum.io/downloads

  • They don't offer installer for ARM( a.k.a `aarch64` or `armhf`) architecture though, which my Chromebook has. – Huge Apr 20 '17 at 20:12
