Hello everyone,
I am using the shape_optimization.py python script to complete the Design Features tutorials but when I run the configuration file with -n 4 option: Code:
python shape_optimization.py -n 4 -g CONTINUOUS_ADJOINT -o SLSQP -f inv_NACA0012_basic.cfg Code:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8a in position 14: invalid start byte Code:

Being a python script which automates the procedure, I can re-write it to include mpiexec -n #cores when running the DIRECT and the ADJ problem but I would like to know what I am doing wrong. For the DIRECT problem, I can use mpiexec -n #cores fine. Thank you for any help |
