Scorpio 3.0.2

[Modern Times]

I failed to get the last version of Scorpio running after spending quite a lot of time on it, so decided enough was enough. I don't mind having to carry out some detailed steps, as long as there is a high degree of certainty that it will work at the end. And there seems something fundamentally weird with running the engine from a batch file in the GUI. I'd rather not do that either. I think that was only necessary to give the path, and I'm happy setting the system variable myself on that.

IIRC you were able to get it working on the command line but not in a GUI. Now UCI is supported natively so you could try that instead.
The installation is easy: download and double-click the installer

https://github.com/dshawul/Scorpio/rele ... nstall.bat

I have now made it so that it generates the calibrate.dat file, needed for INT8, during installation so there is almost nothing the user has to do manually now.
If the user prefers, he can edit scorpio.ini to change networks to use, floating point precision, number of GPUs etc...

About guarantees, nothing in life is guarnteed, so you will have to try and find out or not

Amen Brother..I'm with you on that case...Had lots of trouble getting Scorpio to work from the earliest times..v2.76 and v2.77 were a big problems...(ini file).. v2.7 x32 was infected by some sort of code/virus my antivirus programs liked to eat and now with this "Scorpio net fiasco situation" "I've about reached my limits of patience" Too much time on setup..(exe works but no moves made x64)...I do like Scorpio although results have been spotty in most/all of my tournaments with Scorpio not winning or placing in the top ten in none that I can remember (new or old versions) The JA versions seemed to be easiest to get to work with Scorpio Beta playing well in some of my tourneys for some reason..2.79 Is working but not much success with 2.88 (ini file) 2.9 and 3.0 (ini file issues/problems making the program not able to make moves)...No luck in Fritz, Chess OK and Shredder GUI's its a sad situation..Scorpios ini file setup needs a complete rework..setup too complex, exe can't seem to find the net files...BIG TROUBLE..NEEDS WORK!

The net 42510 (an SE net) has problems with INT8 and TensorRT -- Werner found out the bug, and it will produce garbage result with INT8.
I still have not found the reason why it does not work with TensorRT when smaller nets of same architecure, such as badgyal, work just fine with INT8. However, you can still use 42510 in HALF precision mode, but it will be slower.. I recommend to use 32930 till i figure out the reason.

Ah. OK. Same here. 42510 plays horrible with INT8...32930 seems to work

If you find the problem, it would be nice to get Net T40B.4-160 from J.Horthos, which is the best Net so far and it is 20x256 SE, too. No need for a 42510 Net, which is outdated.

It seems the behaviour is random. I got the J13-410, which is a 24x320 net, working with INT8 (it is SE, WDL+convolutions head) and it works fine).
I don't know how strong a net it is but i can updload it.
Maddex-SE which has exactly same architecture as T40 alsow works fine with INT8.
But T40 and T40B.4-160 do not work with INT8...

Strange...
But a upload of J13-410 would be interesting, of course. It is a large net, so a fast computing with INT8 could be a strong playing solution.
But J13B.2-178 would be somewhat stronger - around +10 Elo.
("J13B.2 attempt to improve on J13 using the same method as for T40B.4")

I would love to do a testrun with that net and Scorpio. But before, I will test Scorpio 3.0.2 with Net 32930 in the near future. Because I have a testresult of lc0 with Net 32930 already, so this testrun will make a comparison possible (does lc0 or Scorpio play better with the same net?!).
Stay tuned!

Ok, it works here:

[White "Scorpio 3.0.2 MCTS+NN J13B.2-200"]
...and I am quite sure this Scorpio scores better than LCZero with the same net.

Cool !!!

I will test that. Now, there is no need for testing Scorpio with the old 32930 Net, anymore. I will test Scorpio (INT8-speed, of course) with that Terminator-Net (J13B.2-200)
And I will test lc0 with the same net, too. 3000 games each. Then, we will se, which engine uses the net better...
Because I have 2 RTX2060-Notebooks, now, the testrun of Scorpio will start now (will take 6 days). And the lc0-testrun will start Friday(?), when the Allie 0.5dev testrun is finished.

Stay tuned!

From Scorpio-website (important): "Oct 7: Added WDL head support. T40 were problematic with INT8 so those are replaced with a Terminator net J13B.2-200 from JHortos. It is a 24x320 net and uses SE, WDL head, convolution policy. To use this net you have to add wdl_head 1 in scorpio.ini, otherwise result will be bad although it may seem it is working properly."

[Daniel Shawul]

Indeed make sure to use lateest scorpio exe that has "WDL value head" support, and also set "wdl_head 1".
I am afraid many people are going to make this mistake since wdl_head is not on by default -- only net that needs it is the J13B.2-200.
The difference between the two is that without WDL, only the winning probablity without draws is optimized i.e. W, while the latter optimizes
W+D/2. It is almost indistinguishable the difference between these two if you run it from the start position.

I am going to run a tournament between these two to see how they behave. I expect the WDL head to be better since I expect the W head to screw up in some position, but who knows maybe optimizing just W gives a more aggresive engine ( I am already surprized that it seems to work Ok).

Indeed make sure to use lateest scorpio exe that has "WDL value head" support, and also set "wdl_head 1".
I am afraid many people are going to make this mistake since wdl_head is not on by default -- only net that needs it is the J13B.2-200.

Of course. I use Scorpio 3.0.2 and set wdl_head to 1 in the scorpio.ini file.

Update: The testrun of Scorpio 3.0.2 with wdl_head 1 and Net J13B.2-200 is a disaster: After 380 games the score is only 28.2% vs. 6 AB-Engines, which means a SPCC-Elo of 3200, which is really, really bad (Scorpio 3 Maddex has 3343 SPCC-Elo). So, there is definitly something very wrong with Scorpio when using that net.
So, I started the testrun of Scorpio 3.0.2 Net 32930 this morning and after 100 games the result is much better: 60.5%, which is at the same level, that Lc0 32930 reached in my testings (60%). So, with N32930 all works fine, but with Net J13B.2-200 not...
