python-2.7 - 值错误: Could not reserve memory block

Question

我在 AWS 上设置 Superset 并尝试加载数据示例时遇到此错误:

Traceback (most recent call last):
  File "/usr/local/bin/superset", line 10, in <module>
    manager.run()
  File "/usr/local/lib/python2.7/dist-packages/flask_script/__init__.py", line 412, in run
    result = self.handle(sys.argv[0], sys.argv[1:])
  File "/usr/local/lib/python2.7/dist-packages/flask_script/__init__.py", line 383, in handle
    res = handle(*args, **config)
  File "/usr/local/lib/python2.7/dist-packages/flask_script/commands.py", line 216, in __call__
    return self.run(*args, **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/superset/cli.py", line 95, in load_examples
    data.load_world_bank_health_n_pop()

    pdf = pd.read_json(f)
  File "/usr/local/lib/python2.7/dist-packages/pandas/io/json.py", line 211, in read_json
    date_unit).parse()
  File "/usr/local/lib/python2.7/dist-packages/pandas/io/json.py", line 279, in parse
    self._parse_no_numpy()
  File "/usr/local/lib/python2.7/dist-packages/pandas/io/json.py", line 496, in _parse_no_numpy
    loads(json, precise_float=self.precise_float), dtype=None)
ValueError: Could not reserve memory block

如何解决这个内存限制？

我有同样的问题(在 512M AWS)并通过添加交换解决。
