Error in Multithreading? #16

Closed fischerdom closed 6 years ago

fischerdom commented 7 years ago

Hey guys,

It seems that pyphi isn't stable anymore. I got a multithreading exception:

Traceback (most recent call last): File "/usr/lib/python3.4/multiprocessing/queues.py", line 242, in _feed obj = ForkingPickler.dumps(obj) File "/usr/lib/python3.4/multiprocessing/reduction.py", line 50, in dumps cls(buf, protocol).dump(obj)

Could you maybe help me with this issue?

Hi Dominik,

This should have been fixed a few days ago. What commit of the develop branch are you on? Try updating to the latest commit and see if the problem still comes up.

Cheers, Will

rlmv commented 7 years ago

Yes, @fischerdom this should be resolved with the latest code. Please let us know if this shows up again and I'll investigate further.

Hey,

many thanks for the answer. Yes it was an older version. I will make an update and tell you if the exception still occurs.

Cheers Dom

fischerdom commented 6 years ago

Unfortunately, I still get the exception. Somehow on a random manner.

I removed the package via pip and reinstalled it, before...

rlmv commented 6 years ago

Interesting. And this is with the head of the develop branch? (pip install git+https://github.com/wmayner/pyphi.git@develop?)

One workaround is to disable parallel computations - that's not great for speed but at least you won't have any errors. Would you be willing to share the code that's causing these issues?

fischerdom commented 6 years ago

Sorry, I missed this mail. Yes it was with the branch. I did an uninstall/install before running the experiments. Now I just returned to the last working version.

Schöne Grüße Dominik Fischer

Ok, thanks for the report. Would you be willing to share the code that's causing the issue?

This should be fixed in the both the 0.9.0 and 1.0.0 releases.
