Scorpio 2.8.7 MCTS+NN windows version

[Daniel Shawul]

You need to include the whole libtensorflow-core.a archive. If you don't do that it will link but
will fail at runtime.

I have brought back the static linking option so do a git pull on the egbbdll repo and compile again
after commenting out those two lines.

Yes, if you use the bazel option, you need to set the correct directory in the makefile as you pointed out.

Doesn't work, either.
Thank you for trying to help, Daniel.

In hindsight I think the underlying problem is the static build of tensorflow_cc
which seemed to be broken right from the beginning.
I'm not sure building the shared library in addition was the correct solution.

Eventually I will try to remove all installed stuff and do a fresh build.

Later.

Great to see Scorpio pushing this direction!!

I sent you a PM about this too, but if you would like Scorpio included in the next CCCC (chess.com/cccc), please let me know!

Just tried the Windows Version, too.
Doesn't work, egbbdll64.dll simply doesn't load.

Joerg, you might want to download _everything_ again including the scorpio exe here (https://github.com/dshawul/Scorpio/releases).
At one point I had an AVX built egbbdll that will not work on older CPUs. I have also modified the load_nn() call this morning
that needed recompiling of scorpio and egbbdll etc. I have also added networks trained from 4 million games and tested it on windows
machine on the CPU. The GPU version is also tested on a linux computer.

Hi Daniel,

just done.
Still the same behaviour, unfortunately.
egbbdll.dll 4.1 loads just fine.

I wonder if the new egbbdll works for others ...

I'm also puzzled about the almost non-existent interest, in general.
Your project seems to offer a great opportunity to try out and gather experience
about MCTS, NNs of different sizes and their training possibilities. Amazing.

Do you have the new egbbdll64.dll in your ScorpioBases as well? I had a similar issue as you but placing egbbdll64.dll in my ScorpioBases as well solved it for me. However I am using the GPU version.

[Joerg Oster]

Yes, that's the only place it needs to be, afaik.

Did you also try a fresh download and tried that one?

I tested it on windows 10. The dependecies of egbbdll are all in the system32 directory.
Btw you don't even need to set Path env. variable for the CPU version now since tensorflow.dll is not needed anymore.

Yes, it would be great to get confirmation whether the new dlls work/or not from others.
