Spyder editor issue: when graphic backend is changed to automatic, plot will not show unless editor is closed

[ariannajojo]

Problem Description

Hello, I'm using the editor for Spyder 3.2.8 to graph plots for a class. I need them to appear in a separate window. It was recently updated from 3.1.4, and now the graphs appear inline when I run the file. I researched how to change it with Tools>Preferences>iPython console>graphics. But even setting it to automatic (or any of the other options) and restarting Spyder causes the console to continue "connecting to the server" without ever connecting. When I run the code, the graph does appear in another window but only when I close Spyder entirely, andI can't view it for long since it closes along with it.

For some context, I am mainly using a conda created environment to do this, but the same result occur inside and outside the environment.

I really need the plots to appear in a seperate window so I can enlarge them since the graph comes out too small when saving it as a PNG (or using Snipping tool). Any help is appreciated.

What steps will reproduce the problem?

1. Updating/resetting spyder
2. Attempting this inside or outside a conda environment
3. Restarting spyder and the linux terminal

Thanks for reporting.

I really need the plots to appear in a seperate window so I can enlarge them since the graph comes out too small when saving it as a PNG (or using Snipping tool).

This is entirely unnecessary, and far better done just by using matplotlib's savefig command (or an equivalent in any other half-decent plotting package).

Nevertheless, this appears to be a duplicate of #6452 and is an upstream problem, not anything with Spyder , and can likely be fixed by a simple conda install ipykernel Please try that,
along with the steps listed in the Spyder Troubleshooting Guide, specifically the Basic First Aid and Emergency CPR sections, which resolve the great majority of Spyder installation issues.
