If you have anaconda installed it should be as easy as:
>> conda install qutip
Anyway, here's a guide :
http://qutip.org/docs/4.1/installation.html
Be sure to meet all the requirements!
thank you sir i have installed qutip and all the packages required but while running the following code to test the packeges installed properly in spyder it is giving error message .
import math

else:

print("Stopping here.")

sys.exit(1)

if minor >= 5:
print("Testing Python version-> py{}.{} OK".format(major, minor))
else:
print("Warning: You should be running Python 3.5 or newer, " +
"you have Python {}.{}.".format(major, minor))

else:

def test_sympy():

print("Running using Python {}".format(sys.version))
test_is_python_35()
test_numpy()
test_scipy()
test_pylab()
test_sympy()
test_pytest()
it is proving output as

Most probably anaconda's python doesnt have these modules. You should install by 'pip install ' on windows powershell or use '>> conda install '
You should first sign up to your Anaconda navigator (top of right hand corner), then select "environments" from left side list, type "qutip" into "search packages" blank, you can then see the qutip through the below list, select and apply it by clicks, follow installation...
