Warning when solving parametric problem

Hi everyone,
I have a question related to some warnings that come up when solving a parametric problem

\mu \Delta u = f

say for \mu\in[1, 2]. Each time the system is solved, a warning of the following type displays:

The code works well and the results are not affected, looking to the path a cache file is created in which the variational form (I guess) is stored. Is this fine? Moreover, is it possible to avoid the display of these messages?

Thanks in advance

You can either:
Downgrade setuptools or Upgrade ffcx, see

I downgraded setuptools to a previous version and the messages display no more.

Thank you very much for the help! :slight_smile:
