Re: [modeller_usage] Modeller 8v1 on x86_64

With the generic UNIX install of Modeller 8v1 on x86_64 RHEL 3, the

Yes - this is because Modeller contains Python 2.3, while RHEL 3 still has Python 2.2. 


To work around this, I've added the following line to our mod8v1:

if test "$ARCH" = "x86_64"; then export PYTHONPATH=/usr/lib64/python2.2; fi

There may be other ways to fix it, but this worked for me.
Well, that will probably work, but you're mixing Python modules between versions 2.2 and 2.3. Binary (.so) modules will almost certainly not work, and even pure Python modules might act strangely. So I wouldn't recommend that.
Other solutions are to upgrade to RHEL 4 (which ships with Python 2.3) or to install Python 2.3 from python.org.
