Jupyter using the wrong version of python

Question

Hi I\'ve installed python 2.7 but did not remove 2.6. i\'ve added 2.7 to the path and also as an alias but it seems like when I do jupyter notebook it tries to access 2.6

Answer 1

It looks like you installed jupyter as an extension of /usr/lib/python2.6. If so, you'd have to uninstall jupyter and reinstall into your desired python.

Answer 2

It could be a problem in your python kernel.json configuration. For example my python kernel is located at:

/usr/local/share/jupyter/kernels/python/kernel.json

and contains:

    {
     "language": "python",
     "display_name": "Python 2.7",
     "argv": [
      "/usr/local/bin/python2.7",
      "-m",
      "ipykernel",
      "-f",
      "{connection_file}"
     ]
    }

Make sure that the path in argv section points to correct version of python.
