No running Jupyter session. Try closing and re-opening this file.

I installed Atom and then the package jupyter-notebook inside of it. After that, I use the atom to open a note book file. It is running correctly. But when I was trying to run it, I got the error message, saying that "no running jupyter session, trying closing and re-opening this file". I already searching this online for a while. Following the related link https://github.com/jupyter/atom-notebook/issues/31
I already set the path to jupiter binary, and also tried to update the kernel gateway.

pip install --user git+https://github.com/jupyter-incubator/kernel_gateway.git@master or pip3 install git+https://github.com/jupyter-incubator/kernel_gateway.git@master

Could anyone help me out with this? Many thanks for your time and attention.

Start by reproducing the reported error when running a notebook in Atom with the jupyter-notebook package, then review the related issue at https://github.com/jupyter/atom-notebook/issues/31 and the configured Jupyter binary and kernel gateway. Done means opening and running the notebook no longer reports that there is no running Jupyter session.
