LC0 For Android!!! History Made!!

[Laskos]

Do android devices have powerful GPUs?
If not, then I guess it stinks on android.

Correct no GPU, but it will not stink if you use a one of the smaller nets offered by dkappe - GM+ strength on a Pi ( similar to a weak andriod) .

Wow, works like a charm with DroidFish (just set the weights filename and path manually). Using 64bit version, BLAS backend, 4 threads (4 faster cores), dkappe 11258-48x5-se network. Getting about 400 nps after 4-5 seconds. Beats the hell out of me. Usual Leela style, GM-like. Very fun!

As it beats me like a duck, maybe I will check its strength against some other engine.

Thanks everybody in this thread.

Does it show how many nodes per move it's calculating?

Can someone explain how to correctly install the engine under Droidfish? I have Android 8.1.0 64 Bit. I installed the engine (blas) and copied a distilled network to the same directory. The engine loads, but it does not runs.

Approx 200knps. I am using small net.

Problem with Acid Ape.

Can anyone explane why LC0 Android does not works under "Acid Ape Chess Grandmaster." I have set the same Engine Settings like with/in Droidfish, but the Engine does not calculate.

[abik]

2. Chess for android, not ok

Actually you can run LC0 in Chess for Android too with an extra setup step.

• Copy lc0 binary and weights files to /sdcard
• Install engine from SD card on lc0
• Install engine from SD card on weights file (not intuitive, but this puts file in right place)
• Import engine lc0

After this you can play lc0. The auto-discover default will find the weights file in the same directory.
