Is it possible to compile a version for the 32 bit CPU armv7l Raspberry Pi? I managed to compile LC0 using openblas and can get up to 100 nps on 3 cores, but I’m having problems compiling your engine.

Thanks,

Al.
Scorpio itself can be compiled for arm 32/64 bit no problem -- I have actually done that before for android.
To use the NN you would need to compile egbbdll using tensorflow or tensorflow-lite using bazel.
I have seen people do that before but I have not tried it myself.

I have uploaded both now. The default supports sse2 intructions and is the one that should work for you.
Those with modern cpus can use the one in avx/ sub-folder.
Let me know if it works for you now.
working well now, many thanks

I just played a 3 + 2 blitz game against version 2.8.8, using 2x32 nets with the sole change from default parameters being my changing treeht to 5000.

I gave Scorpio a book made from the decisive games of 2700+ players, because in the first game he played 1.d4 d5 2.Qd3 against me, making it impractical for training without a book.

I am using Windows 10 on a Macbook 2015 model via BootCamp, so the hardware is relatively dated.

Would appreciate any advice on strengthening it up a bit.

Daniel,
just for your information, the Linux version crashes immediately (memory access fault) if I don't set "use_nn" to 0 in the ini file.

Hi Brendan,

I have mentioned this but try backup_type = 0 (minimax intstead of averaging). That is much better tactically.

Finally someone who uses linux...where have you been ? :)
Note that I haven't provided egbbdll binaries compiled for linux so you have to compile it yourself.
The easiest method there is to use the tensorflow_cc approach I described in the readme after changing USE_TF=1 (not 2).
Then you do a make in the egbbdll src and hopefully you get egbbso.so which you rename as egbbso64.so and put it somewhere
to be used by Scorpio.

The second approach is to put the egbbdll src inside tensorflow (I put it in tensorflow/cc/egbbll) after cloning the tensorflow repo and
build it with bazel like

bazel build --config=opt --config=monolithic //tensorflow/cc/egbbdll:egbbdll.so

Both methods work put i prefer the tensorflow_cc approach for linux.

I am using Windows 10 on a Macbook 2015 model via BootCamp, so the hardware is relatively dated.

Would appreciate any advice on strengthening it up a bit.

Hi Brendan,

I have mentioned this but try backup_type = 0 (minimax intstead of averaging). That is much better tactically.

Thanks Daniel, I must have completely missed when you said it.

As a non-programmer, much of this language is meaningless to me, which doesn't help.

But I'll give backup=0 a try.

Thanks again.

Not your fault, I said that in the other scorpio-nn thread not this one. Also use mt=16 that should double your nps compared to mt=1

Code: Select all

backup_type 0
mt 16

Bye Bye
Finally someone who uses linux...where have you been ? :)
Note that I haven't provided egbbdll binaries compiled for linux so you have to compile it yourself.
The easiest method there is to use the tensorflow_cc approach I described in the readme after changing USE_TF=1 (not 2).
Then you do a make in the egbbdll src and hopefully you get egbbso.so which you rename as egbbso64.so and put it somewhere
to be used by Scorpio.

The second approach is to put the egbbdll src inside tensorflow (I put it in tensorflow/cc/egbbll) after cloning the tensorflow repo and
build it with bazel like

bazel build --config=opt --config=monolithic //tensorflow/cc/egbbdll:egbbdll.so

Both methods work put i prefer the tensorflow_cc approach for linux.

I also prefer the 1st approach.

I'm currently in the process of building and installing tensorflow_cc.
There are many warnings during the process, though.

OK, seems to have finished correctly.

Unfortunately, building egbbdll fails.
It looks like there are many header files included inside the tensorflow_cc header files
like "error_codes.pb.h", which aren't present after building and installation.
It seems I don't have any header file with "pb.h" in its name.

Maybe something went wrong during the build process?

Btw., where can I download the egbb files currently?
The links on your website seems to be outdated.
