[nengo-user] Problem on running nengo_gui

[鄭士康]

Hi,

Here is another problem in importing nengo.
I installed nengo 2.0.1 in the IDE PyCharm,
and created a new project with a python file
with only one line: import nengo
I ran the file, and the message I got is

Fatal Python error: Py_Initialize: can't initialize sys standard streams
LookupError: unknown encoding: x-windows-950

Process finished with exit code 3

Is there anything I missed?
Thanks for any responses and answers.

Sincerely,

主旨: [nengo-user] Problem on running nengo_gui

Hi,

I used Anaconda (Python 2.7) to successfully install nengo and nengo_gui in Windows 8.
However, when I type nengo_gui within Anaconda Command Prompt,
I got :

Added C:\Users\Shyh-Kang\Anaconda and C:\Users\Shyh-Kang\Anaconda\Scripts to PATH.

C:\Users\Shyh-Kang\Anaconda>nengo_gui
C:\Users\Shyh-Kang\Anaconda\lib\site-packages\IPython\nbformat\current.py:19: UserWarning: IPython.nbformat.current is deprecated.

- use IPython.nbformat for read/write/validate public API
- use IPython.nbformat.vX directly to composing notebooks of a particular version

            (translation from Chinese message) Attempted to access communication port,
            because of insufficient privilege

Can anyone tell me how to solve this problem? Many thanks in advance.
By the way, the same procedure is applied in another computer with Windows 7,
and I can open the nengo gui successfully there.
