Assuming you have the wrong backend system you can change the backend kernel by creating a new or editing the existing kernel.json in the kernels folder of your jupyter data path jupyter --paths. You can have multiple kernels (R, Python2, Python3 (+virtualenvs), Haskell), e.g. you can create an Anaconda specific kernel:

$ /bin/python3 -m ipykernel install --user --name anaconda --display-name "Anaconda"

Should create a new kernel:

/kernels/anaconda/kernel.json

{
    "argv": [ "/bin/python3", "-m", "ipykernel", "-f", "{connection_file}" ],
    "display_name": "Anaconda",
    "language": "python"
}

You need to ensure ipykernel package is installed in the anaconda distribution.

This way you can just switch between kernels and have different notebooks using different kernels.
