Rayon (rn-3.9) is the strongest open source go AI

Shoreline · **#41**

I got an alert from the author that Rn.3.10.2 windows binary version is available for download. But it requires GPU

Gomoto · **#42**

Can you provide the link to the binary? Thanks.

When I compile this it says it is version 8.0.1, the same as a compile from one year ago.

There is link "6 releases", pick the latest one, rn3.10, which was released just couple of days ago

Thanks but it won't compile:

g++ -O3 -Wall -std=c++11 -g -c src/UctSearch.cpp -o src/UctSearch.o

You have to download the CNTK as well and add the cntk/Include directory to the includes path when compiling. Either add to your PATH in general or add

Code:

-I /path/to/cntk/Include

When you link at the end you'll need to add cntk/ctnk/EvalDll.dll (I think it was called) to the list of objects on the file command make does.

Thanks for the link, i use it just now to play with Drago. I can use the gtp window to show win percentages and to suggest moves ("genmove b" or "genmove w" for example).

Are there any options to show alternative moves and win percentages in the gtp output available?
Or are there any other hidden analysis features available already?

Dear Rayon developers,

thanks for your outstanding work on this engine. It is very nice to have such a strong open source engine available. I am looking forward to analyze my games with your engine. And it even makes sense to develop some custom tools for analyzing because the engine is open source :-)

Regards
Gomoto

Can ypu post an instruction on how to compile? Cause I'm unable to compile it.
Is there a way to run this on an engine like Drago or fuego?

Thanks, but I still have problems. After downloading cntk I get this error:

src/UctSearch.cpp: In function ‘void ParallelUctSearch(thread_arg_t*)’:
src/UctSearch.cpp:1263:15: error: ‘atomic_int64_t’ in namespace ‘std’ does not name a type
static std::atomic_int64_t queue_full;
^
src/UctSearch.cpp:1281:25: error: ‘queue_full’ was not declared in this scope
std::atomic_fetch_add(&queue_full, 1);
^
I can remove the function:

void
ParallelUctSearch(thread_arg_t *arg)
{
}

And get the next error:

/home/alex/Programme/Engines/Go/Rayon/src/UctSearch.cpp:2070: Nicht definierter Verweis auf `GetEvalF'

I can fix this by:

// GetEvalF(&nn_model);

And it compiles but of course it don't work:

./ray
Init CNTK
Get EvalModel failed

zakki · **#49**

Perhaps you need to link libeval like

Code:

-L<cntk lib dir> -leval

.

If you compile on Linux, maybe you need to compile CNTK too, as bihonglu writes he has done in the first post here: https://github.com/zakki/Ray/issues/5.

In the meantime I was able to compile ray with: -L/home/alex/Downloads/cntk/cntk/lib -L/home/alex/Downloads/cntk/cntk/dependencies/lib -leval

I downloaded the bin version of cntk and used the install script, my problem was that I have to "activate" cntk before compiling...

Code:

alex@alex-Aspire-VN7-791:~/Downloads/Ray-rn-2.3$ source "/home/alex/Downloads/cntk/activate-cntk"

CNTK is activated.

When I started ray I got this kind of error messages:

Code:

./ray: error while loading shared libraries: libcudart.so.8.0: cannot open shared object file: No such file or directory

I copied the libraries to the /lib directory and now I am stuck with this error:

Code:

How did you add it to drago? What does your engines.config look like? I downloaded the binary and then cntk (based on the readme) but I don't have any success with drago, gogui, or just trying to run Rn.3.10.2.exe in a command window. :-(

Same. I'm still trying to compile this thing

How to play with Drago:

Binary for Win 64 & Nvidia GPU:

https://github.com/zakki/Ray/releases

Add the engine manually after adding this to the engines config file in the Drago directory:

[Ray]
url = https://github.com/zakki/Ray/releases
connection = not.required
level = not.handled
boardsize = not.required
chinese.rules = not.required
japanese.rules = not.handled
time.per.move = not.handled
total.time = not.handled
overtime = not.handled

This are just the settings I am using, not the optimal settings. Drago can pass commandline options to the engine. And you can use the GTP window too.

Regards
Gomoto

Is there the way to optimize this engine on i7 computer? I tried but it's failed. Anyway, thanks for the guidelines
