Enthought Python, Mac OS X 10.6, and Spyder DMG

[BR]

I recently installed EPD 7.3 on my macbook running OS X 10.6, and then
installed Spyder via the DMG
(spyder-2.2.0dev_py27_Snow_Leopard_rev2296.dmg). Unfortunately, it
appears that when you install Spyder this way, it just uses the Python
version that comes installed with OS X rather than EPD. I say this
because it reports

Python 2.7.3 (default, Jul 12 2012, 13:52:05)
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin

in the Spyder console window at startup, but when I invoke python from
the terminal I get

Python 2.7.3 |EPD 7.3-2 (64-bit)| (default, Apr 12 2012, 11:14:05)
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin

Now, I think I have solved the problem, but I would like to get
confirmation. In Spyder, I went to Preferences>Console>Advanced
Settings and then reassigned the "Path to Python Interpreter
Executable Binary" to what I think is the EPD executable binary. I
found it in /Library/Frameworks/EPD64.framework/Versions/7.3/bin/
python. Now when I startup Spyder I get

Python 2.7.3 |CUSTOM| (default, Apr 12 2012, 11:14:05)
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin

This matches what I get at the terminal, besides the |CUSTOM|, so I
think it's correct. Is there anything else I need to do?

Hi,

You found the right solution but there is still a bug that prevents from
loading the EDP libraries from the Spyder App.

I know how to fix it but it's a bit tricky and I haven't had time to sit
down and just do it ;-) I hope to find some spare time next weekend.

Cheers,
Carlos

Thanks for your reply.  I will keep an eye out for an update!

Carlos,

Any luck squashing that bug?

[Carlos Córdoba]

Hi,

I solved it already, sorry for not telling you. It's in our new DMG for
Spyder 2.2beta2. Please download and test it to see it works for you :-)

Cheers,
Carlos

Carlos,

Thanks for the update!  I installed the 2.2 beta2 on my home computer, gave it the path to the basic (free for anyone) version of the EPD, restarted Spyder, and got a few errors on startup. Here is what shows up in the console:

Any idea what to do to fix this?  I will see if I get the same thing at work where I have the full version of the EPD.

Thanks in advance for your help!

[BR]

Ok.  Here is the console output when I use the full version of EPD.  It looks the same as the free version of EPD, except the first few lines are missing.

Hi Firas,

We have transitioned our discussion to the follow site:

http://code.google.com/p/spyderlib/issues/detail?id=1277

I still cannot run EPD with Spyder, but it seems like I am getting closer.

[Carlos Córdoba]

To solve the first error, you need to go to:

Tools > Preferences > Console > Advanced Settings > PYTHONSTARTUP replacement

and select the option

[ ] Default PYTHONSTARTUP script


About the second error: have you updated IPython on EPD to version 0.13.1? By default EPD 7.3 comes with IPython 0.12.

Cheers,
Carlos

Hey Carlos, BR,

I am also getting these errors in the Python console. 

When I try to switch to the iPython console, I get the following errors: 

Traceback (most recent call last):

  File "/Applications/Spyder.app/Contents/Resources/site.py", line 120, in <module>

    import sitecustomize

    return getattr(self._sock,name)(*args)

Please help!

To anyone else reading this: note that to update iPython to 0.13.1, you need to issue the following commands :

sudo enpkg enstaller

sudo enpkg ipython

sudo is unfortunately necessary as it will give you a very confusing file not found error. 

Carlos, thanks for getting me up to date but I'm still having issues - will discuss here:
