Communication failure in MXNet with BytePS about byteps HOT 3 CLOSED

Hi qingyang, here's the clarification to some of your questions.

Does the python3 setup.py install of BytePS replace mxnet/3rdparty/ps-lite with byteps/3rdparty/ps-lite?

No.

If no, how does BytePS initialize it's own server and scheduler at the beginning of training, and at the same time, prevent the initialization of server and scheduler in import mxnet (they may occupy the DMLC_PS_ROOT_PORT)?

If you do not intend to use BytePS and MXNet KVStore at the same time, you don't need to worry about this. BytePS server is inited through "import byteps.server". You can check the code of byteps/server/__init__.py.

BTW: we do not maintain mxnet > 1.5.0

Ok, I get it. I fond "import byteps.server" in launch.py... Then I should add it to my training python file.
But I still need to manually stop MXNet's initialization of server and scheduler in "import mxnet".
Maybe MXNet 1.5.x is different from 1.5.0 . LOl.

Oh, I get it. In server and scheduler side. I only need to run "import byteps.server" and nothing else.
Then I don't have all those problems mentioned before.
Thanks again.
