cannot connect to ('127.0.0.1', 20099)

Hi, Qin.

I replace RunEnv with gym's Walker2d environment. But cause the error below: (farmer) cannot connect to ('127.0.0.1', 20099): [Errno 111] Connection refused (farmer) fp.acq() failed on 127.0.0.1:20099

How to fixed this bug?

you mean RunEnv worked, but Walker2d didn't?

Usually, a connection refused error is due to:

• Your firewall not letting connection to port 20099 thru
• Your account running the script does not have the privilege to start a connection
• You did not start the slave script (farm.py) as per README
• Or, you started the slave, but it cannot listen on port 20099 due to privilege or firewall settings
