traceback when trying to Fit

mestia commented 8 years ago

HI, with the version 0.9.3 I am getting the following traceback when loading a test session and clicking Fit. Does it work for you ?

Thanks, Alex

Hi, which version of lmfit are you using?

The Windows build uses lmfit 0.9.2.

I also use lmfit 0.9.2 on Ubuntu.

This page suggests that lmfit in debian/jessie is version 0.8.0. Could this be the problem? I did not think of that when I moved to lmfit. I just saw that it already is in the debian repositories, but did not check the version.

Hi, Yes, that was the case, for testing I used Jessie and the lmfit version 0.8.0. It works with 0.9.2. Thank you!
