importerror no module named caches

Question

I'm trying to run simulation by using gem5 on ubuntu 16.04 lts and I write code './build/X86/gem5.opt ./configs/tutorial/two_level.py' .

The output on terminal was:

Traceback(most recent call last):
    File "<string>", line 1, in <module>
    File "home/park/gem5/src/python/m5/main.py", line 433, in main
     exec filecode in scope
    File "./configs/tutorial/two_level.py", line 3, in <module>
     from caches import*
ImportError: No module named caches

I tried everything I can, but couldn't know. What is the problem?

Answer 1

The file:

configs/tutorial/two_level.py

has never been part of the main tree according to:

git log -p -- '**/two_level.py'

so you must provide its source.

Supposing you are talking about configs/learning_gem5/part1/two_level.py , the problem is not reproducible on master at da79d6c6cde0fbe5473ce868c9be4771160a003b with the command:

./build/X86/gem5.opt configs/learning_gem5/part1/two_level.py 

which appears to run correctly.
