AttributeError: module 'numpy' has no attribute 'complex'

Question

I am trying to make a real number complex using numpy. I am using numpy version 1.24.3

Here is the code:

import numpy as np
c=np.complex(1)

However, I get this error:

AttributeError: module 'numpy' has no attribute 'complex'.

Answer 1

np.complex was a deprecated alias for the builtin complex.

Instead of np.complex you can use:

complex(1)         #output (1+0j)

#or

np.complex128(1)   #output (1+0j)

#or

np.complex_(1)     #output (1+0j)

#or

np.cdouble(1)      #output (1+0j)
