Dear scikiters,
I am facing the following problem: using scikit 0.11 to run a grid
search on SVC's parameters works well, but the same code using stable,
or dev. version fails just after the multiprocessing part.
Here is a sample of error stack (each worker fails in the same way) :
Process PoolWorker-1:
Traceback (most recent call last):
File "/usr/lib/python2.6/multiprocessing/process.py", line 232,
in _bootstrap
self.run()
File "/usr/lib/python2.6/multiprocessing/process.py", line 88, in run
self._target(*self._args, **self._kwargs)
File "/usr/lib/python2.6/multiprocessing/pool.py", line 57, in worker
task = get()
File "/usr/lib/python2.6/multiprocessing/queues.py", line 352, in get
return recv()
UnpicklingError: NEWOBJ class argument has NULL tp_new
I imagine it has to be with a specificity of my setup, however have you
any leads on which I could start ? Thanks.
All the best,
François.
