SystemError: unknown opcode when scatter/gather /pull/push

Bắt đầu tại ipyparallel/util.py, cụ thể là entry point _pull được đề cập trong traceback, và tái hiện việc gán và lấy dữ liệu bằng dview với các phiên bản Python, IPython và ipyparallel đã nêu. Kiểm tra scatter, gather, pull và push trên cluster Linux/Windows; được xem là hoàn tất khi các thao tác này hoạt động mà không gặp lỗi unknown-opcode hoặc segmentation fault.

I am running a cluster with Linux/windows machines.

I cannot any longer use scatter/gather/pull/push variables.

In windows this is the error the engines print in the screen

On linux it generates a seg fault.

On the session I am using as a console (linux) I get the following

`In [6]: dview["qwerty"]=33

In [7]: dview["qwerty"]

I am on python 3.5.2, using ipython 4.0.2 and ipyparallel ( all systems ) 6.0.2

I checked google and this does not look like being reported by anybody else.

This has worked fine in the past. First time I am facing this issue
