Run hellopim.sh

[Second222None]

Dear Sir,

Many thanks for a great job. I'm interested to run a hello case located in PIMSim/GEM5Simulation/gem5
However, when I try to execute hellopim.sh in PIMSim/GEM5Simulation/gem5, I receive the following error, I really appreciate it if you please shed a light on this and help me to solve it

Configuration：Ubuntu 20.04 Python 2.7.18 gcc-4.8.1 g++-4.8.1
