I am having the following error in gem5. I've tested it on X86 only and it causes fatal error.

Command:

sudo ./build/X86/gem5.opt configs/example/se.py --cmd /usr/bin/python3.5 --options "train.py --scenario simple" --caches --l2cache --cpu-type=TimingSimpleCPU --mem-type=DDR3_1600_8x8 --mem-size=1024MB

Execution output:

I am compiling in Ubuntu 18.04 with python3
Any help would be appreciated :)

Please let me know if I'm executing the algorithm with gem5 properly.

Thanks!
