Do you know what's the format of the stderr/stdout of leelaz?

[HackYardo]

I'm writing a GTP Web GUI named "VastGo" for fun, I want to run not only KataGo but also GNUGo and Leela-Zero as well.
The output of KataGo and GNUGo are plain string in terminal and Sublime editor, but the Leela-Zero's are plain string in terminal and mystical format? in Sublime editor, and there are NO document or issue about in Leela-Zero's repo. See below (the command is leelaz -g -w path/to/weight.gz -v 361 --noponder --cpu-only):
In terminal (without stderr):

quit

In Sublime:

0000 0000 0000 0000 0000 0000 0000 0000

In cat command:

Detecting residual layers...v1...128 channels...6 blocks.
Initializing CPU-only evaluation.
Setting max tree size to 4360 MiB and cache size to 484 MiB.

The three above are all wrong!!! It should be (with stderr):

Using 8 thread(s).
RNG seed: 14907218604829807376
BLAS Core: built-in Eigen 3.3.7 library.

What's the format of the stdout/stderr of Leela-Zero?

[kaorahi]

not sure what you are asking... You seem to have some trouble when you tried to use Leela Zero. But I cannot understand what is your trouble (what you did on what environment, why you think it is a trouble, ...). If you are asking about Sublime Text, I can answer nothing as I've never used it.

For the protocol, see GTP and "lz-analyze" in GTP_Extensions.md. These documents (and some trials on a terminal) should be enough to know how to use Leela Zero. GTP consoles on Lizzie or Sabaki may be also helpful though they hide the outputs of "lz-analyze".

• Thank you tons! It is a bit bad to learn LZ via KG, LZ should have a doc.
• Yeah, I want to implement a GTP console like Sabaki or Lizzie by putting std IOE streams in a file.
• The story of the mystery format: I write the LZ's stderr to a file in binary format and the stdout in plain text format, so that the file is not text or binary format, it is a mystery format for sure.
• Thank you a lot.
