Spyder with Anaconda 4.0 fails to start IPython terminal

[ijstokes]

I have a virgin install of Anaconda 4.0 (for Python 3.5). The very first thing I did was start Spyder. The IDE started, but I got this error message in the bottom right window:

An error ocurred while starting the kernel
Error in sitecustomize; set PYTHONVERBOSE for traceback:

I am on a 64-bit Windows 8 system.

can you start ipython by itself? specifically Jupyer ipython in qt ?
I had a similar issue with the install on 2 out of my 3 machines; this thread fixed it though. Note that there are two possible solutions on it

Thanks @ijstokes for reporting. Which Windows version are you using?

[venergiac]

same for me,

after spyder --reset

it works, but I have to reconfigure the workspace.
Normally it happens (in my opinion) when the kernel crashes or remains in stuck

Windows 7 version, anaconda 3 4.0.0 64bit windows

@venergiac, it seems your Numpy installation is broken. Please run

conda install -f numpy

to fix it :-)

[venergiac]

Tx , but after

conda install -f numpy

no module name pycosat

then I tried

conda install -all

and the anaconda installation was corrupted.

Then I reinstalled anaconda (uninstall, install for all user).
Then again

import numpy.core.numeric as _nx
AttributeError: module 'numpy' has no attribute 'core'

after

spyder --reset

I reconfigured spyder, and worked well.

I replicated the issue with the following procedure

script.py

 PORT = 8000
    httpd = socketserver.TCPServer(("", PORT), MyrHandler)

    print("serving at port", PORT)
    httpd.serve_forever()

then killed the kernel with the red button, and again:

AttributeError: module 'numpy' has no attribute 'core'

I think this was tied to some problems with the configuration files. Pretty sure this is now resolved in more recent versions of Anaconda. If anyone experiences this with Anaconda >= 4.3 please shout.
