Problem with fipy and gmsh

[fipymigrate]

running the circle example from diffusion I get the following error:

We will try to diagnose. What version of numpy are you running?

[fipymigrate]

print numpy.version
1.5.1

Works for me on Ubuntu with

• python 2.7.1
• fipy 2.1.1 tarball
• gmsh 2.5.0
• numpy 1.5.1

Do you still have the issue? I'm closing this ticket, but will reopen if you respond. Cheers
