I was running AFNI before updating without any problem, but it suddenly doesn't work with the message below, whenever I am trying to run python files.
Below is the message I received.

**************
env: python: Bad CPU type in executable


AFNI program opens well, but I can't run ~ .py files.
echo $0 shows 'tcsh'.


How can I solve the problem?
