Looking at the multiprocessing code, the default seems to be to spawn 20 processes, which might overwhelm some systems. Would you mind changing the number of processes to a lower number, say 2, and rerunning the script? Unfortunately, I can't reproduce this on my machine and would appreciate your help with debugging this issue. Thanks!

The error that you get, multiprocessing.pool.MaybeEncodingError: Error sending result:
, seems to indicate that Python is having trouble pickling and unpickling the results from the workers that are spawned. This might be specific to some older Python version. Do you mind telling me the version of Python and the operating system you are using?

Hi Mizuho: I'm also not able to reproduce your error. I have however made a change to turn off multiprocessing (9e9510f). Can you please try with a single process (set --num-procs 0
) and see if the problem persists?
