hi every body
I download nupic-master and in example file i click on opf and then click on clients and i want to run hot gym prediction code in python. but when i run ‘swarm.py’ I encounter this error :
“Can’t connect to MySQL server on %r (%s)” % (self.host, e)) pymysql.err.OperationalError: (2003, “Can’t connect to MySQL server on ‘localhost’ ([Errno 111] Connection refused)”)
Please help me solve this error.How should I run this code?

Did you install nupic and all the dependencies? what is your os?

As you can read here, you need to setup a MySQL database for the “coordination logic between each of the worker processes”.

Yes I install every thing

Thanks a lot,so I should read this doc :pray:
