How do I run two separate instances of Spyder

Spyder dev here) This is very easy. You need to go to:

Tools > Prefences > General

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.




You can use the --new-instance option as well. Just run

spyder --new-instance
