Ipython kernel is not working in spyder of anaconda3 newly installed on my Windows10 laptop. It is displaying an error,

"Permission denied" error seems to be what triggered this, and the triggering process was "secure_write" to an os directory, which implies that some necessary process did not have admin write permissions. Maybe it did not run under an admin account? That's all I can discern from this traceback, but I have not used ipython before so someone else may have more insight. – Sciborg

To fix this you need to update the jupyter_client package, with the following command:

conda update jupyter_client
