function cannot be pickled for mongodb

When using hyperopt.mongoexp.MongoTrials for parallelism, I am getting the same error as expressed in this StackOverflow thread. In my case, because I am using hyperas, the error says hyperopt.mongoexp:job exception: No module named temp_model.

I believe I have made my function self-sufficient, and I have installed dill. Is there anything done to the function by hyperas that would make it temp_function impossible to pickle? Has anyone else successfully used hyperas with mongodb?

I got it to work by commenting out the lines in optim.py that removed temp_model.py. From there I:

• specified an absolute path to my data file in data()
• Set my trials to: trials = mongoexp.MongoTrials('mongo://localhost:27017/jobs/jobs', exp_key='htm_113_108')
• set $PYTHONPATH to include my project directory containing temp_model.py
• Ran the worker script with: ./hyperopt-mongo-worker --mongo=localhost:27017/jobs --exp-key=htm_113_108

@mcgibbon @myhussien sorry, this one slipped my attention. I’ve never used hyperas with mongodb, but it’s doomed to fail. hyperas writes a temp file that the mongodb workers have to have access to. In principle that can work, but hyperas (as of now) isn’t built for it.
