Import error in Rec Model

I'm getting the error "cannot import name moduleTNC" when I try to import the recmodel_client in a Python script.  It had been working fine until last week.  Any suggestions?  Thanks.

    HI @panellio, could you include the full text of the exception including the traceback?  That'll help a ton with pinpointing where the error is occurring.

  • Hi James, thanks for the response, here's the full text of the exception:

    Hmm, this looks like there's an issue with one of the submodules from the scipy package.  I wonder if a recent package upgrade or downgrade in your virtual environment might have caused something to break.  In any case, could you try reinstalling scipy and see if that happens to fix the issue?

  • Good call James...upgraded scipy from 1.0 to 1.1 and it works now.  Thanks!
