I have updated qiskit to the newest version using pip install qiskit --upgrade and all was done successfully, and when I write pip list on the command line I get:

As I should. But then I run help("modules") on a jupyter notebook and get:

which I don't understand why are there no other modules. And obviously import qiskit throws an error as well. Any idea how to solve this?

PS: This is a follow-up from this question

  • $\begingroup$ Are you using any virtual envs? This sounds like it is probably an issue with your Python path $\endgroup$

    $\begingroup$ you are most probably running a different python distribution/environment on the notebook. If you use conda, see e.g. this page. More generally, make sure to start jupyter from the terminal from the same environment you installed qiskit in. This question isn't really about qiskit, only about how to use python packages $\endgroup$

    $\begingroup$ I'm voting to close this question as off-topic because it has nothing to do with qiskit $\endgroup$

    $\begingroup$ Yes, that was the problem and I managed to solve it directly with the anaconda navigator. $\endgroup$

A workaround to fix this is to manually add the qiskit install location to your python path in the notebook. You can find the path by running pip show qiskit in a terminal, which will return a field called Location. In the notebook then add the following lines

import sys
sys.path.append('the location')

    $\begingroup$ you really shouldn't have to do this. If you installed the package correctly, it will be found. Changing the path manually like this to point to a package installed into another distribution is a great way to mess things up (unless you downloaded the package manually rather than with a package manager). $\endgroup$

    $\begingroup$ But is there any other answer to the question? No. So why the two -1 votes and nasty comment. $\endgroup$
