Issue
The following error occurs due to change in permission in a jupyter environment: It occurs irrespective of execution of a python script or other execution operation with userX.
Bus error (core dumped)
Note: While working with root it works fine.
I remember changing permissions, mainly chmod 755 / and also chmod -R 755 /home/userX with root access.
I guess changing or revoking the file permission should work. But I am unable to figure out. Any help would be much appreciated :)
Solution
The issue was mainly with the memory space somehow, and had to free up space within the user home path and everything seemed to be normal again.
Also to note never to use chmod 777 / in the root directory. This might lead to some changes especially when your using server environment.
