<br>
I reran the install script from scratch every time, just to be
safe. I think I actually may have it working now, after setting <br>
NUMPY_ARGS="--fcompiler=g77". I've tried to load and use several
SciPy functions and no errors so far. Hoping it stays that way!<br>
<br>
Thanks again!<br>
<br>
Cheers,<br>

<div>Have you tried deleting the scipy installation and retrying
from scratch? You should be able to clean up most of the old
scipy installations by repeatedly running "pip uninstall
scipy". If you're patient, you can also try the nuclear
option of rerunning the install script from scratch.</div>

<div>Hi all,<br>
<br>
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:<br>

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.<br>
<br>
Cheers,<br>

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:<br>

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