我使用一个SGE集群，在头节点上运行IP控制器，在其他节点上运行约50个引擎（使用QSUB提交）。引擎能够连接并向控制器注册，没有任何问题。我还可以使用SSH连接到头节点并查看引擎ID并运行简单代码。例如，这非常有效：
%px %pylab inline
parallel_result = lbView.map_sync(lambda x: x*rand(), range(32))
但是，当我尝试运行以下行时，引擎崩溃了：
%px from sklearn.svm import LinearSVC
出现以下错误：
importing LinearSVC from sklearn.svm on engine(s)
[Engine Exception]
Traceback (most recent call last):
File "/usr/global/anaconda/lib/python2.7/site-packages/ipyparallel/client/client.py",
line 713, in _handle_stranded_msgs
raise error.EngineError("Engine %r died while running task %r"%(eid, msg_id))
EngineError: Engine 0 died while running task '48c99848-0784-4ea1-a8c9-900685e955a3
当我在集群头节点上的IPython实例上运行它时，完全相同的命令非常有效，甚至在另一台服务器（无SGE）上使用IPyparallel，其中有12个引擎在本地运行。
我已将日志记录级别设置为debug，这是引擎和控制器输出的内容：
