TensorCirucit c.draw() NameError

I want to plot a circuit build with TensorCircuit using the draw method.

I am working on Google Colab and have pip installed qiskit. Yet i get NameError: name 'QuantumCircuit' is not defined. I have also tried from qiskit import QuantumCircuit but still i get the same error.

Executing the code on another JuypterHub works.

Solution

pip install qiskit
pip install pylatexenc

import numpy as np
from qiskit import *

Once you are done with above code you have to restart your runtime so that installed library come into force into your colab environment.

For restarting runtime:

Click on Runtime
Select Restart runtime 
Select Run all

This help you to rectify your problem.
