Streaming server printing empty lines #478

Open shaynemei opened 9 months ago

When using the endpointer, the streaming server would print empty lines like this:

There seems to be one empty line per segment (whenever endpointer is triggered)

Where can disable this behaviour?

Have you changed any code? Can you reproduce it with the latest master?

shaynemei commented 9 months ago

This is from the latest master

Sorry, I cannot reproduce your issue with the latest master after commenting out the following line:

https://github.com/k2-fsa/sherpa/blob/115b8568bf90dfb866d8aa4a682e37862201e609/sherpa/bin/streaming_server.py#L695

This is from the latest master

By the way, your log shows you are actually not using the latest master.

For instance, https://github.com/k2-fsa/sherpa/blob/115b8568bf90dfb866d8aa4a682e37862201e609/sherpa/bin/streaming_server.py#L665-L668

The connected log should be at line 665. But your log shows line 683, which indicates you are actually using a modified version.

Please re-test it with the latest master and see if you still have this issue.
