How to install and import Qiskit_aqua?

Question

I want to run SVM algorithm using Qiskit. For this purpose I need to import some packages from qiskit_aqua.utils. I am writing my code on Google Colaboratory. But while trying to import this package it shows me the following error.

ModuleNotFoundError: No module named 'qiskit_aqua'

I have tried to import every thing from Qiskit. But no changes have come. Here is my code.

!pip install qiskit
from qiskit import * 
from qiskit_aqua.utils import split_dataset_to_data_and_labels
from qiskit_aqua.input import get_input_instance
from qiskit_aqua import run_algorithm

I even tried to import Aer using this command. But still it is of no use.

Help me finding the solution.

!pip install qiskit
from qiskit import Aer
from qiskit_aqua.utils import split_dataset_to_data_and_labels
from qiskit_aqua.input import get_input_instance
from qiskit_aqua import run_algorithm

Answer 1

Aqua is a subpackage of Qiskit, so you need to use . instead of _. Your imports therefore should be

from qiskit import Aer
from qiskit.aqua.utils import split_dataset_to_data_and_labels
from qiskit.aqua.input import get_input_instance
from qiskit.aqua import run_algorithm
