ipython notebook doesn't work: OSError: [Errno None not found] 2

Question

I follow instruction and run ipython.exe notebook:

Now if I run jupyter notebook, I get:

C:\Miniconda3\Scripts>jupyter notebook Traceback (most recent call last): File "C:\Miniconda3\Scripts\jupyter-script.py", line 5, in sys.exit(jupyter_core.command.main()) File "C:\Miniconda3\lib\site-packages\jupyter_core\command.py", line 186, in main _execvp(command, sys.argv[1:]) File "C:\Miniconda3\lib\site-packages\jupyter_core\command.py", line 104, in _execvp raise OSError('%r not found' % cmd, errno.ENOENT) OSError: [Errno None not found] 2

I need to save my work as ipython notebook. How can I do it?

Answer 1

Like zwol said, your installation might have gotten screwed up. There are two things you can do.

1. Completely remove your miniconda installation and try again.

2. Create a new environment and install ipython/jupyter there. I would try this first.

   conda create -n myenv python=3
activate myenv
conda install jupyter
jupyter notebook
