Numpy reads txt as array in one line

vec = np.genfromtxt( ' wiki.ch.text.vector ' , skip_header=1, delimiter= '  ' , dtype=None) 
skip_header=1 is to skip the first line 
delimiter is the field separator 
because there are str and float in txt , so you need to set dtype=None, only float is read by default, so an error will be reported
