Packaging: pip install pandas pulls in numpy 1.8.1, but isn't linked against that version

[Redoubts]

import pandas fails with ValueError: numpy.dtype has the wrong size, try recompiling, which I would guess is due to the above.

you need to recompile pandas

[Redoubts]

Sure, but pip shouldn't pull in a broken configuration.

pip tries to upgrade things

pip install pandas==0.14.0

[Redoubts]

I think you meant to include --no-use-wheel, since the command you listed still pulls a non-functional binary from the users point of view.

[jreback]

well u didn't include platform / os / numpy info

and u should just upgrade numpy and it will work

[Redoubts]

Using OS X 10.9.

The essence of the problem is the precompiled osx wheel doesn't work with 1.8.1, but unfortunately pip pulls 1.8.1 rather than leaving it alone (because pip is a naive tool).

I guess I'm asking for a refresh of the OS X wheels.

[jreback]

ahh that would explain it

they should be very specific to a version

what is numpy version?

[Redoubts]

OS X 10.9 comes with numpy 1.6.2 stock,
but if you just do pip install -U pandas, pip will compile & upgrade to 1.8.1 for you. I think your stack overflow link promises backwards compatibility, so you may as well compile for the newest version. (Unless you know better)

[jreback]

not that direction
you can put a higher numpy version not lower
u should be using 1.8 anyhow
1.6.2 is really old
or install an older pandas

it will technically work but u cannot use the wheels for osx they are built for 1.8
