How do I run two separate instances of Spyder

I want to be able to have two instances which are completely independent in the sense that I can be working on two separate unrelated projects in different folders without any interference.

Solution

  • (Spyder maintainer here) This is easy. You need to go to:

    Tools > Preferences > Application

    in Spyder 5, or

    Tools > Preferences > General

    in Spyder 4, click the "Advanced Settings" tab, and deactivate the option called

    [ ] Use a single instance

    Then every time you start Spyder a new window will be opened. If you want the old behavior back, just activate that option again.
