I am using spyder3 on ubuntu 16.04 as an IDE for python programming. The problem with spyder3 is when I run my program for the first time, it runs well and the second time I run it shows kernel busy forever, but does not actually do any computation. I need to restart the kernel and then it works gain. But I have to do this for each execution of a program which is not a good practice. I removed and installed spyder3 again, but didnot solve my problem. I will be grateful if anyone can help me to solve this issue.

Thank you very much for your time.


Try that:

  • open Spyder and then click Tools

  • then click Reset Spyder to factory defaults.

If it doesn`t help, try this instead:

  • open the terminal

  • then enter sudo pip install -U spyder.

  • The second method finally worked. Thank you very much :-) @enigma – parupalu Apr 2 '19 at 11:31
