Which LMFIT version was used?

[vzickus]

When trying to run the test case (no modifications after cloning), I get an error associated with lmfit. Could you list the versions of packages you used when distributing the latest version?

simulating spectrum & irf data...

[0.85, 0.147, 0.003]

I am also getting the same lmfit error with WinPython.

Latest version of lmfit that works with the current version 7662ec7 is 0.9.13

After that something broke, I'll try to figure it out if I have time.
