<div class="moz-cite-prefix">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>
<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>

Dear yt users,<br>
<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>
<br>
Cheers,<br>
