TypeError: unhashable type: 'spacy.tokens.span.Span'

I use nlp(text) to get human names from news articles. I gather all PERSON ents into a list but when I try to manipulate the list I get this error: TypeError: unhashable type: 'spacy.tokens.span.Span'

My code:

text='James Harding, professor at the UCL, and Lucy Smith, a student.'
text=u"{}".format(text)
all_tags = nlp(text)
names=[]
for ent in all_tags.ents:
    if ent.label_=="PERSON":
        names.append(ent)
print names
print type(names)
myset = list(set(names)) #remove duplicates
print(myset)
mynewlist = [ x for x in myset if " " in x ] # remove lonely names
print(mynewlist)

Output:

[James Harding, Lucy Smith]
<type 'list'>

TypeError Traceback (most recent call last)
in ()
8 print names
9 print type(names)
---> 10 myset = list(set(names)) #remove duplicates
11 print(myset)
12 mynewlist = [ x for x in myset if " " in x ] # remove lonely names
