我的my_data.nt文件如下所示：

<bob> <name> "Robert" .
<bob> <knows> <amy> .

我正在使用这段代码来解析它：

from rdflib import Graph

g = Graph()
g.parse("my_data.nt", format="nt")

for ele in g:
    print(ele)

我收到此错误：

Traceback (most recent call last):
  File "/Users/x/MyVirtualEnvs/new_python3_env/lib/python3.7/site-packages/rdflib/plugins/parsers/ntriples.py", line 140, in parse
    self.parseline()
  File "/Users/x/MyVirtualEnvs/new_python3_env/lib/python3.7/site-packages/rdflib/plugins/parsers/ntriples.py", line 189, in parseline
    subject = self.subject()

  File "/Users/x/MyVirtualEnvs/new_python3_env/lib/python3.7/site-packages/rdflib/plugins/parsers/ntriples.py", line 235, in uriref
    uri = self.eat(r_uriref).group(1)
  File "/Users/x/MyVirtualEnvs/new_python3_env/lib/python3.7/site-packages/rdflib/plugins/parsers/ntriples.py", line 210, in eat
    raise ParseError("Failed to eat %s at %s" % (pattern.pattern, self.line))
rdflib.plugins.parsers.ntriples.ParseError: Failed to eat <([^:]+:[^\s"<>]+)> at <bob> <name> "Robert" .

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "test_query.py", line 5, in <module>
    g.parse("my_data.nt", format="nt")
  File "/Users/x/MyVirtualEnvs/new_python3_env/lib/python3.7/site-packages/rdflib/graph.py", line 1043, in parse
    parser.parse(source, self, **args)
  File "/Users/x/MyVirtualEnvs/new_python3_env/lib/python3.7/site-packages/rdflib/plugins/parsers/nt.py", line 26, in parse
    parser.parse(f)
  File "/Users/x/MyVirtualEnvs/new_python3_env/lib/python3.7/site-packages/rdflib/plugins/parsers/ntriples.py", line 142, in parse
    raise ParseError("Invalid line: %r" % self.line)
rdflib.plugins.parsers.ntriples.ParseError: Invalid line: '<bob> <name> "Robert" .'

我错过了什么？

当我尝试my_data.nt在easyrdf上的内容时，它似乎非常好。
