I have recently updated my Anaconda and Spyder app! But in this new version of Spyder (version 4), when I restart the kernel (with short key and from console in above ribbon), the Restart kernel confirmation window shows up, Then I press the "yes" button but nothing happens. Can anyone help me with this?

  • (*Spyder maintainer here*) Please be sure to have updated to our latest version (4.1.5). That version has a lot of fixes about kernel restarts. – Carlos Cordoba Oct 20 '20 at 02:58
  • @CarlosCordoba Thanks for your comment. I'm already using (4.1.5) version, but the problem still exists. – Vahid Jebraeeli Oct 20 '20 at 07:34
  • Are you connecting Spyder to an external kernel? By that, I mean a kernel created outside Spyder? – Carlos Cordoba Oct 20 '20 at 15:01

    @CarlosCordoba No, I haven't change the default settings in the Preferences. But I have noticed that before running any code, restarting works very well. But after running any code, it stops working! – Vahid Jebraeeli Oct 27 '20 at 13:21

I have the same problem with Spyder 5.2.2 :

  • Spyder version: 5.2.2 None
  • Python version: 3.7.9 64-bit
  • Qt version: 5.12.10
  • PyQt5 version: 5.12.3
  • Operating System: Windows 10

When restarting the kernel, I get this:

Python 3.7.9 (tags/v3.7.9:13c94747c7, Aug 17 2020, 18:58:18) [MSC v.1900 64 bit (AMD64)]
Type "copyright", "credits" or "license" for more information.

IPython 7.31.1 -- An enhanced Interactive Python.

Restarting kernel...
