Describe the issue:

Exported complex numbers in CSV RAW format can't be imported back in.

real = np.ones((2,2))

imag = np.ones((2,2))

np.savetxt("file.csv", comp, delimiter=', ')

data = np.loadtxt("file.csv", dtype=complex)

Error message:

ValueError: could not convert string '(1.000000000000000000e+00+1.000000000000000000e+00j),' to complex128 at row 0, column 1.
