Hi all,
Thank you all for your suggestions! It turns out that iraf is
installed on my work desktop and it somehow changes the F77
environment variable. After changing it back to /usr/bin/f77 I was
able to install SciPy. However, when I now try to do 'from
scipy.integrate import odeint' for example, I get the following
error message:
In [2]: from scipy.interpolate import odeint

It seems this is again related to the compiler, but I'm not sure
what to do about it. I have tried once more to set the NUMPY_ARGS
to the different options in the install script, and also to
install yt without SciPy and then install it using 'pip install
scipy', but every time I get the same error. My OS is Scientific
Linux 6, by the way.
Cheers,
Caroline

I suspect this is a side-effect of
the iraf virus. I too have often run into the f77 trojan that
comes to light
in some (all?) iraf installations, and configure doesn't deal
with it very well.

Dear yt users,
I'm having some trouble installing SciPy. I can install yt just
fine using the install script, but if I turn the option for
installing SciPy on, I get the following error:

I've tried uncommenting the NUMPY_ARGS lines one by one as
suggested in the script, but none of that seems to work.
I'm using yt version 2.6.1, changeset e0906fc5b6d5, if that
helps.
Any ideas on how to fix this? Thanks!
Cheers,
Caroline
