np.genfromtxt error in python 3

Question

When I use

dataset = np.genfromtxt(open('data/train.csv','r'), delimiter=',', dtype='f8,str')[1:]

I obtain this error

TypeError: must be str or None, not bytes

Could you help me to find the solution?

Why not just `np.genfromtxt('data/train.csv', delimiter=',', dtype='f8,str')`? — Psidom, Apr 05 '17 at 15:49
In PY3 you need to open the file in 'rb' mode (or let it open it for you). — hpaulj, Apr 05 '17 at 16:21

Do not use open within np.genfromtxt:

dataset = np.genfromtxt('data/train.csv', delimiter=',', dtype='f8,str')[1:]
