I am trying to install epdfree on two virtually identical machines: Linux 2.6.18-308.1.1.el5, CentOS release 5.8., 64-bit machines. (BTW, I'm a bit new to python.)

After the install on one machine, I run python and try to import scipy. Everything goes fine.

On the other machine, I follow all the same steps as far as I can tell, but when I try to import scipy, I am told “ImportError: No module named scipy”.

As far as I can tell, I am doing everything the same on the two machines. I installed from the same script, I run the python in the epdfree installation directory, everything I can think of.

Does anyone have any idea what would keep “import scipy” from working on one machine while it works fine on the other? Thanks.

Well, turns out there was one difference. File permissions were being set differently on the two machines. I installed epdfree as su on both machines. On the second machine, everything was locked out when I tried to run it without going under "su". Now my next task is to find out why the permissions were set differently. I guess it's a difference in umask settings? Well, this I won't bother anyone with. But feel free to offer an answer if you want to! Thanks.

The problem is that you don't have the library scipy installed, which is a totally different library of epdfree.

you can install it from apt-get in linux I guess, or going to their website www.scipy.org
