Kernel error (Errno 13 Permission denied) in Jupyter Notebook, Windows 10
Same exact problem here. What worked for me was running the Anaconda Navigator as an Administrator. Hope it works for you too.

I have installed Jupyter Notebook on Windows 10. I can execute jupyter notebook command. It opens and shows a list of current path directories. I also can create or open a notebook. But when I do it I get Kernel error in the top right corner. After clicking on it this window appears:
Failed to start the kernel

The code in my file is not highlighted in different colors and when I run it nothing happens.
I am new to programming, so please try to give advice in simple words, describing each step in detail.
In the past, I've tried to delete Python, install Python in different versions, install Anaconda. In addition, in order to work with tensorflow, I've created a special environment. But this error stays the same. I suspect the problem is a double backslash ("//") in the path, but I have absolutely no idea how to fix this. But perhaps the problem is something else.
