mpi_run.py does not work but DeepMimic.py does

[yjc765]

Hello everyone, when I ran python mpi_run.py --arg_file args/train_humanoid3d_spinkick_args.txt --num_workers 4 to train the agent as the introduction says, there was error like

Running with 4 workers
cmd: mpiexec -n 4 python DeepMimic_Optimizer.py --arg_file args/train_humanoid3d_spinkick_args.txt --num_workers 4
  File "DeepMimic_Optimizer.py", line 25
    Logger.print('Shutting down...')
               ^
SyntaxError: invalid syntax
-------------------------------------------------------
Primary job  terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
  File "DeepMimic_Optimizer.py", line 25
    Logger.print('Shutting down...')
               ^
SyntaxError: invalid syntax
--------------------------------------------------------------------------
mpiexec detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

  Process name: [[1583,1],1]
  Exit code:    1
--------------------------------------------------------------------------

But if I ran python3 DeepMimic.py --arg_file args/train_humanoid3d_spinkick_args.txt --num_workers 4 instead, it worked nicely and started training, but only the statistics of first iteration has been logged to 'agent_log.txt'.

Can anyone help me with these problems or has anyone faced the same problem?

Looks like maybe mpi4py hasn't been installed?

Hello I have fixed this issue

in the file mpi_run.py, there is a part where it runs the DeepMimic_optimizer.py file with python. You have to change the default python to "python3" in that part.

It looks like: cmd = 'mpiexec -n {:d} python3 DeepMimic_Optimizer.py '.format(num_workers)

ah ok, thanks for pointing that out.
