ipython 0.13 zmq错误

我遇到了ipython集群的怪异行为。计算结束，但许多结果永远不会到达客户端（并且在完成第一次计算后，引擎只是闲置）。ipython 0.13 zmq错误

我怀疑东西是错误的，因为ZMQ 1）不时我看到了以下错误：

File "/data/misc/nano/python/env_stable/lib/python2.7/site-packages/IPython/parallel/client/asyncresult.py", line 118, in get 
    if not self.ready(): 
    File "/data/misc/nano/python/env_stable/lib/python2.7/site-packages/IPython/parallel/client/asyncresult.py", line 132, in ready 
    self.wait(0) 
    File "/data/misc/nano/python/env_stable/lib/python2.7/site-packages/IPython/parallel/client/asyncresult.py", line 142, in wait 
    self._ready = self._client.wait(self.msg_ids, timeout) 
    File "/data/misc/nano/python/env_stable/lib/python2.7/site-packages/IPython/parallel/client/client.py", line 1058, in wait 
    self.spin() 
    File "/data/misc/nano/python/env_stable/lib/python2.7/site-packages/IPython/parallel/client/client.py", line 1015, in spin 
    self._flush_results(self._task_socket) 
    File "/data/misc/nano/python/env_stable/lib/python2.7/site-packages/IPython/parallel/client/client.py", line 814, in _flush_results 
    idents,msg = self.session.recv(sock, mode=zmq.NOBLOCK) 
    File "/data/misc/nano/python/env_stable/lib/python2.7/site-packages/IPython/zmq/session.py", line 642, in recv 
    idents, msg_list = self.feed_identities(msg_list, copy) 
    File "/data/misc/nano/python/env_stable/lib/python2.7/site-packages/IPython/zmq/session.py", line 673, in feed_identities 
    idx = msg_list.index(DELIM) 
ValueError: '<IDS|MSG>' is not in list 

Additionally IPython.zmq has two test failures: 

====================================================================== 
ERROR: test_send (IPython.zmq.tests.test_session.TestSession) 
---------------------------------------------------------------------- 
Traceback (most recent call last):

    socket = MockSocket(zmq.Context.instance(),zmq.PAIR) 
    File "/clusterdata/python/env_stable/lib/python2.7/site-packages/IPython/zmq/tests/test_session.py", line 34, in __init__ 
    self.data = [] 
    File "/clusterdata/python/env_stable/lib/python2.7/site-packages/zmq/sugar/attrsettr.py", line 38, in __setattr__ 
    self.__class__.__name__, upper_key) 
AttributeError: MockSocket has no such option: DATA

    raise RuntimeError("context could not terminate, open sockets likely remain in test") 
RuntimeError: context could not terminate, open sockets likely remain in test 

----------------------------------------------------------------------

我用pyzmq 13.0.0（如安装由PIP），以及zeromq 3.2.2 ，由pyzmq的设置编译。我使用ipython 13.1和python 2.7.3。

这是什么可能的任何建议，如果不是我怎么能找出更多的信息为什么会发生这些错误？

更新：事实证明，减速是由于ipcontroller的长任务队列，然后采取100％的CPU和滞后可怕。这是一个单独的问题，但我仍然会对上述的反馈感到满意。

MockSocket错误只影响测试本身，并在0.13.2 [此处发布候选版本]（http://archive.ipython.org/testing/0.13.2）中修复。 – minrk 2013-03-27 21:34:53

不知道其他错误可能是什么？另外，根据更新，ipcontroller是否应该像地狱一样滞留4000个职位（如果它不会滞后几百个）？ – 2013-03-27 22:09:32

这显然不应该，但这并不意味着你的系统出了问题。如果你有很多工作，我强烈建议将TaskScheduler.hwm设置为大。 – minrk 2013-03-28 05:09:13

回复@minrk的留言。 ZMQ错误是不重要的，性能是由于计划，并通过设置TaskScheduler.hwm=0解决。
