Debug the source in my own machine

[zenglw06]

If I want to add some features, how can I debug the source code. I want to inspect more information as the code runs. And I didn't find the debug instruction.

You can check this https://github.com/bytedance/byteps/blob/master/docs/env.md#byteps-debug

The most useful one is this

export BYTEPS_LOG_LEVEL=TRACE

But it may print too many things. The following will only print things during initialization stage.

export BYTEPS_LOG_LEVEL=DEBUG

What exactly the info do you want to get?
