ImportError: dlopen: cannot load any more object with static TLS

Thanks for making this available! I have found that the import order matters in a surprising way:

If I use

import seaborn
import limetr  # needs to be imported before seaborn to work. weird, huh?

I receive the following error

---------------------------------------------------------------------------

If I reverse the order of these imports, it works. This only happens in my Jupyter notebook. In a python interpreter on the command line, I can use either order.

Thanks @aflaxman ! In the new version of limetr we move to use solver from scipy instead of cyipopt. We do not have control of cyipopt and scipy is more compatible.
