mathplot lib not loading in Spyder.

[Stanley Rosenbaum]

I am running Spyder on a Mac.

After the updates this morning in Anaconda, I can't get my Spyder scripts to run.

I get a mathplotlib import error.

Any suggestion how to get around this?

Thank

Hi,

Please run

    conda update qt

to fix this problem. I also want to mention that the current Anaconda's Spyder is failing in Mac for a different reason, but that will be fixed during the day :-)

Cheers,
Carlos

Hello, I just reinstalled and updated my anaconda about an hour ago and am trying to run my python scripts in Spyder on a Mac. I had the same problem as Stanley Rosenbaum and tried Carlos Córdoba's fix. However, I am still getting the same error (see below) in Spyder (and also can't get matplotlib to load in python at all actually). Was this problem ever fixed?

Yes, the problem is fixed.

You need to run

    conda update qt
    conda update matplotlib

to get the solution.

Cheers,
Carlos
