clean port install of python and opengl, attempted python module import fails

[jacoblee@…]

I am not sure this is a port error, but...

Start with no ports at all I install python27

$ sudo port install python27

..no errors or warnings..

and then

$ sudo port install py27-opengl

..no errors or warnings..

Then I load python and try to import:

ValueError: numpy.dtype has the wrong size, try recompiling

I've read that this might have to do with a package that was compiled using another version of numpy?

Replying to jacoblee@…: p.s. I also ran the command: sudo port select --set python python27

If py27-opengl is installed, then so is py27-numpy since py27-numpy is a dependency of py27-opengl-accelerate, which is in turn a dependency of py27-opengl.

In my memory, the ValueError happens when a given port was installed using a given version of NumPy, then NumPy was updated but the given port was not. So, it seems likely that py27-opengl-accelerate need to be rebuild for a newer NumPy. I recommend that you build from source; try:

sudo port -f uninstall py27-opengl-accelerate
sudo port -s install py27-opengl-accelerate

first and then see if the import works. Chances are that it will. If that's the case, then we need to rev-bump py*-opengl-accelerate.

Works for me, and I haven't rebuilt any of this stuff since initially installing it.

[michaelld (Michael Dickens)]

Great; thanks for reporting back!

[jmroot (Joshua Root)]

Uh, what? Did you mistake me for the reporter?

[jacoblee@…]

This ticket was closed by mistake, as noted by jmr.

In any case, Michael's recommended fix worked. Thank you!

[jacoblee@…]

p.s. the tip about using the -s flag is something I'll keep in mind in the future.

@jmr: haha! yes, I wasn't looking carefully about -who- responded.

@Jacob: I'm glad that did the trick! Thanks for reporting back.

I'm leaving this ticket as closed :)
