[CP2K-user] unexpected printing breaks the ase-cp2k calculator

[Sun Geng]

Dear CP2K users,

I encountered a problem with the ase-cp2k calculator when using the 
cp2k-v7.1.

Below is the error message, in which the cp2k_shell.psmp unexpectedly 
prints the message " HINT in environment.F:814 The compiler target flags 
(x86_avx2) used to build", and breaks the code in the python part.

Is there a way to disable the HINT message?
Thanks.
Geng
