Does this problem only occur when using LeelaSabaki, or will Leela Zero crash as well when attached to Sabaki?

tangjin commented 5 years ago

When I used Sabaki and Leela Zero, I can play 3 steps, then the Leela Zero crashed, but the Sabaki was running. Path: /data0/leela-zero/src/leelaz Arguments: -g -t 4 -w /data0/leela-zero/best-network --playouts 1 --noponder image

Then it's not a LeelaSabaki problem. There's most likely a problem in your Leela Zero binary. Can you try running Leela Zero in your Terminal to see if it crashes when you play some moves?

tangjin commented 5 years ago

When I used Leela Zero only, I can play many steps, the Leela Zero didn't crashed. /data0/leela-zero/src/leelaz --noponder -t 4 --playouts 1 -w /data0/leela-zero/weights.txt image

Ok, then I need more information on the crash: How do you know Leela Zero crashes; does its process simply disappear? Does Sabaki give any errors or is it stuck with a busy cursor? Did you wait for 37 seconds for Leela to respond? Also, is it normal for Leela Zero to answer at A16; this doesn't seem like a normal move?

Hi, Yishn

  1. It is stuck with a busy cursor, and the process disappear in my Terminal.
  2. ps ax|grep leela, cannot find the process.
  3. I wait for 120s
  4. Leela Zero answered at A16, because I set the playouts=1 ?

Thank you.

@tangjin I have exact same issue on High Sierra, sometimes even the whole system halts. Calling it with your arguments: leelaz --noponder -t 4 --playouts 1 -w weights is fine, but normal functionality is not possible.

This problem was described in this issue: https://github.com/gcp/leela-zero/issues/1677 Hopefully it will be fixed in the next version of leela-zero

@Jendker Thanks a lot.

I discussed the issue with OpenCL here: https://github.com/gcp/leela-zero/issues/1951. The problem discussed in mentioned issue is already fixed, so the only solution is the driver fix, but as Apple is abandoning OpenCL (OpenCL is deprecated https://developer.apple.com/macos/whats-new/) this will likely not happen... Still, running on CPU works fine, so it's not that all bad.
