You should pass the contents of the xml file in ET.iterparse() instead of string my_schema.

Change your code to:

from io import StringIO

xml = "file.xml"
f = open(xml, "r")
xml_data = unicode(f.read() , "utf-8") 
my_namespaces = dict([node for _, node in ET.iterparse(StringIO(xml_data), events=['start-ns'])])

from pprint import pprint
pprint(my_namespaces)
