我正在尝试使用StarCluster和ipyparallel设置群集。当我尝试运行以下命令时，我收到以下错误。我从未见过python错误 以这种方式错过了堆栈跟踪。
from ipyparallel import Client
rc = Client()
ipview = rc[:]
res = ipview.apply_async(lambda x: x+3, 3)
res.get()
我收到以下错误：
[0:apply]:
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)<string> in <module>()
TypeError: 'CannedFunction' object is not callable
[1:apply]:
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)<string> in <module>()
TypeError: 'CannedFunction' object is not callable
甚至不确定从哪里开始调试。
如果有人知道为什么没有错误的Traceback会很有帮助。我以前从未见过这种追溯。
