As could be seen in the pic, 0.0.0.0:2379: bind: address already in use
I surmise some old etcd process is running on your machine?

The reason you said I have considered. I have checked the pod 2379, it is free. And I run the programmer in a docker container. So the address is free.

But I couldn't see any other reasons that could cause the address already in use error 😂
Try the following:

1. nc -vl 2379 to ensure the port could be listened, then cancel the nc by Ctrl-C
2. kill previous etcd process pkill etcd
3. Start graphscope again.

Hope you could try the above ways and share the results.

I test nc -vlp 2379, ensure the port could be listened. Then conduct pill etcd , start the gs again. The same bug occurred.

@Pomelochen Try:

graphscope.set_option(etcd_listening_client_port=2479)
graphscope.set_option(etcd_listening_peer_port=2480)

Before creating the session. See also #1903 and #1910.

Unfortunately, I try to change the port as you said. And other ports, the same bug address already in use.

I have made some changes to reduce the dependency of analytical engine on etcd in #2889, which is expected to be available in tomorrow's nightly build. By then, you could upgrade your graphscope installation by

pip3 install -U grpahscope --pre -i https://pypi.org/simple

and try again (the nightly build will be available tomorrow, not today).

Ok, I will try it. If possible. You can try to make a image with ubuntu20.04, and pip graphscope. And run the image on a machine with os readhat7.5,use graphscope on hosts. You may have the same bug. I have try several machine, meet the same bug.

Ok, I will try it.

Nightly CI failed last night, please wait for another day.

Rerunning, expected to be available in an hour.

It's available now.
