ipython console slow response in Spyder

Hi,

I am attempting to use Spyder that came with my new install of Anaconda, but the ipython console within Spyder is extremely slow for anything, such as starting takes 1-2 minutes and even something such as 5+5 has a 5-10 second delay to get a response. If I run jupyter qtconsole from the Anaconda prompt, it will say kernel died a few times, but eventually start and then work normally e.g. 5+5 has an instant response.

If I do jupyter qtconsole and then connect to the .json that was created from that using the “Connect to an existing kernel” it looks like my ipython terminal in Spyder works fine, minus the variable explorer which is less than ideal.

I am using Windows 7 Enterprise

Downgrade ipykernel from 5.10 to 4.10 solved my problem here. conda install ipykernel=4.10.

Please update to our 3.2.8 version and try again. Also, please update Qt/PyQt to their latest version. For that, please open the Anaconda Prompt and run there

conda update spyder qt pyqt
