Unexpected warnings during engine startup / game play about botli

[IbaiBuR]

I also get this kind of warnings / errors which also seem to be related to the usage of the experience file:

ERROR:asyncio:Exception in callback Protocol._line_received('info string ...BlackHole.exp')
handle: <Handle Protocol._line_received('info string ...BlackHole.exp')>
Traceback (most recent call last):
  File "/usr/lib/python3.10/asyncio/events.py", line 80, in _run

python-chess warns that the engine produces unexpected output.
Looking at the output it is also kind of strange, these are all legal moves from the starting position with their respective evaluation, I guess the engine does this to inform about the information from the experience file?

On which engine is your "mod" based?

No, this error is not related to that. It occurs at occasional intervals and does not seem to have any negative effects.

It is based on latest Stockfish-Dev.

Yes, the engine sends the moves to the GUI / cli or whatever to give some information about the available moves in the experience file, obviously, the NPS, TBHits and time are sent as 0 because the engine does not really "think". This is the part of code that sends the info:

                      //Provide some info to the GUI about available exp moves
                      int expCount = 0;
                      for (auto it = quality.rbegin(); it != quality.rend(); ++it)
                      {
                          ++expCount;

                          sync_cout
                              << " info "
                              << " depth "    << it->first->depth
                              << " seldepth " << it->first->depth
                              << " multipv 1"
                              << " score "    << UCI::value(it->first->value)
                              << " nodes "    << expCount
                              << " nps 0"
                              << " tbhits 0"
                              << " time 0"
                              << " pv " << UCI::move(it->first->move, rootPos.is_chess960())
                              << sync_endl;
                      }

I tried to hardcode it and send different values to avoid the warnings but it did not work either.

If the assertionerror does not have negative effects then no problem. The warnings dont seem to have negative effects either but it is a bit annoying that they pop up continously in the terminal.

Thanks for answering. If you need more information just tell me.

Sorry I didn't expect you to have actually added the experience file yourself.

What I wonder, why is there a space before info an info output normally looks like this: info depth 4 seldepth 2 multipv 1 score cp 51 nodes 110 nps 55000 hashfull 0 tbhits 0 time 2 pv e2e4. Maybe this is already part of the problem?

[IbaiBuR]

That could be the problem...

Let me remove it, recompile, and try...

Maybe that eliminates the warnings.

[IbaiBuR]

You were right!

Thanks a lot!
