When i run the command python start.py -m mf -d amazon2014,i got this problem

RuntimeError:Unable to connect to Redis at 127.0.0.1:6379

i have installed redis
i start the redis-server.exe and redis-cli.exe.The server is now ready to accept connections on port 6379.
but if i run the python start.py -m mf -d amazon2014,there will be RuntimeError:Unable to connect to Redis at 127.0.0.1:6379

i run your code in windows
how to solve the problem
please thanks

Hey
I'm not sure about your issue. From what I see, 6379 is the default port when running ray tune so maybe you might have a conflict in the packages. I would maybe suggest looking at the version of the packages, in particular of ray, in the .yaml file

thanks for your reply
These days,i create a new configuration environment,installing all necessary packages.I'm sure the ray is 1.6.0,the redis is 3.5.3 the same as your yaml file.But it's still this issue.
When i don't run the redis-sever.exe,runing the command python start.py -m mf -d amazon2014,Show the following questions:

RuntimeError:Unable to connect to Redis at 127.0.0.1:6379 after 16 retries.Check that 127.0.0.1:6379 is reachable from this machine.If it is not,your firewall may be blocking this port.If the problem is a flaky connection,try setting the environment variable'RAY_START_REDIS_WAIT_RETRIES'to increase the number of attempts to ping the Redis server.

i'm sure the firewall has been stopped.
Then,when i start the redis-sever.exe,runing the command python start.py -m mf -d amazon2014, only show this questions:

RuntimeError:Unable to connect to Redis at 127.0.0.1:6379

I have setted environment variables of Redis in path that is installation Path of Redis.And I have tested Redis to work properly, but I don't know why running this code causes this error
Is it because of version issue of python or torch?
