Grünauer san,

Thank you for your report!

Could you send it via "Bug report/Feature request" link in the main menu?
It adds related information to help me know issues in detail.
This is the official, highly recommended way.

I could not reproduce your issue in version 5.6.0, which was released on 17:00 Sep. 20th UTC.

Thank you for your cooperations.

y_ich-san,

I've sent the report. The mail doesn't contain a lot of information, though - just that it's an iPad 2018 (though it also happens on an iPhone 8 Plus), both running the latest OS version with the latest version of your app. Both devices do not have a Neural Engine.

I have also verified that the bug occurs for every KataGo weight, but not for any other weight.

Thank you,

Marcel

Dear everyone,

As Grünauer san kindly reported it, fixing the issue of KataGo on iOS 14/iPadOS 14 by the version 5.6.0 was not complete.
If your device does not have Neural Engine, please stay in iOS 13/iPadOS 13.
If your device has Neural Engine, I think that it works hopefully.

Thank you for your patience.

Hi y_ich,

Thank you for fixing the app for neural engine iOS devices so fast. Both of mine (2019 iPad Air and iPhone 11 Pro) work well.

I wish you good fortune in fixing the others too!

y_ich-san,

thank you very much for your bugfixes in v5.7.0. KataGo now works again on devices that have a GPU but not a Neural Engine.

It also feels a lot faster; KataGo seems to get at least twice the number of visits in the same time, sometimes maybe a lot more.

Grünauer san,

I am glad to hear it from you.
In order to avoid Core ML bug, eventually I could simplify weights.
In next release, KataGo will run a little bit faster by optimization.

Thank you for your cooperations!

Hi.

I bought a new iPad Air.
It is really, really amazing.

KataGo 40b runs at more than 130 eps.
minigo v17 is also boosted at more then 200 eps.
Other weight runs at almost double speed of A13.

A14 processor seems to have no bottlenecks by global pool layers, which slow down KatakGo and minigo weights on A13 or earlier.

Has anyone tried running this on one of the new Macs that should be compatible?

wineandgolover san,

It should be compatible but I haven't released it on Mac App Store since I haven't confirmed whether it works well or not.
I will release it when I buy an M1 Mac.

Please wait for a while.

Hello, Chinese users.

"A Master of Go" was removed from China App Store by Apple since they recognize the app as "Game".
I have no way to get registration number from China government.

Today I released a restricted version, "与围棋老师复盘".
You may find it by searching on App Store.
You cannot play a game with AIs but you can study a game with AIs.It is an educational app.

I will keep update this app together with "A Master of Go".

The differences between the last version of Chinese "A Master of Go" and "与围棋老师复盘" are follows.

. You cannot play a game with AIs
. supports multiple windows on iPadOS.
. supports Handoff.
. includes handicap stones for scoring in Chinese rule in consistency with AIs.
. improved settings UI.
. updated KataGo to v1.8.0.
. updated Leela Zero and SAI weights.
. improved showing a variation by long-press.
. supports KGF free handicap SGF.

Not so much differences, so you may hesitate to buy a similar app.
I will sell it at half price until 2/19.

Thank you!

I upgraded my copy to incorporate KataGo via the in-app store. Apple took my money. The program did not give me KataGo.

I tried deleting and re-installing the app. That didn't work.

On my iPhone I can click the "go to in-app store" and it just invites me to but the KataGo add-on again!. On my iPad the in-app click doesn't even work.

On the iPhone, when I go to the in-app page and click Restore, I get a message saying Katago is now unlocked. I see no evidence of that on my iPad. The iPad is not the latest but is not very old.

What's going on?

Fairbairn san,

Thank you for using the app and I am sorry for your inconvenience.
Could you send e-mail to me by "Bug report/Feature request" link at the bottom of main menu?

E-mail's template automatically describe your environment(versions of related devies and softwares).
They are helpful for me.

Thank you.

For the record, I sent a bug report and got an immediate response. The suggestion made was to install the latest version as a temporary fix, but the real problem will have to await the next version.

That worked - up to a point, Lord Cropper. It did not work at once. I only discovered it worked by trying again a little while later. I'm guessing there was a download going on in the background. But I expect a message telling me that. More important, I thought updates were done without any manual intervention, beyond telling the App Store app to go ahead and install the queue of updates.

I tried the app. I've become resigned to the fact that all apps are a Magical Mystery Tour, but this one has more mysteries than most. What's wrong with a simple page of instructions, for heaven's sake?

Among the so-far unresolved mysteries, I'll mention a few.

1. Once in a game I could find no way to get out of it except by resigning. Where's the magic button?

2. There's a scales icon. What is it?

3. There is a thumb-and-finger OK icon. What is it?

4. The scores/winrates are given in the following fashion:

74.6%(+24.4%pt)/5.0±24

I have no idea what %pt is meant to be. I'm guessing 5.0 is meant to be the score difference in points (as per Katago), but then what possible practical value is a score difference "between -19 and 29"?

5. I can see no way to paste an sgf. These two boxes are permanently greyed out.

6. Batch size? What's that?

Thank you y_ich, I see you have updated Master of Go to 1.8.0. Great! Will it continue to match the features with the Chinese version going forward?

Fairbairn san,

I am sorry for a lack of manual.

>> 1. Once in a game I could find no way to get out of it except by resigning. Where's the magic button?

A game will end when you resign, or an AI resigns, or both pass. No magic buttons.
At handicap game with default AI engine, the AI may miss the timing of resign if you beat it perfectly.
Please resign in such a case.
KataGo engine will treat such cases well.


>> 2. There's a scales icon. What is it?

It is for estimating score for default AI engine and is for visualization of territories for KataGo engine.


>> 3. There is a thumb-and-finger OK icon. What is it?

They are rates matching with AI's recommendation play moves.
If it shows high rate, it indicates that you are playing such as AI.

>> 4. The scores/winrates are given in the following fashion:
>>
>> 74.6%(+24.4%pt)/5.0±24
>>
>> I have no idea what %pt is meant to be. I'm guessing 5.0 is meant to be the score difference in points (as per Katago), but then what possible practical value is a score difference "between -19 and 29"?

The value of %pt is the difference between previous and current winrates.
If it is a large negative value, you have played the wrong move.
If is is a positive value, you have played an excellent move at which AI is surprised.

You are right, 5.0 is a score difference and 24 is a standard deviation of the score.


>> 5. I can see no way to paste an sgf. These two boxes are permanently greyed out.

You need to "copy" an SGF on other apps before pasting.
("Copy" means "copy" in "copy and paste" operation.)
Please "copy" an SGF and invoke the app. Then the buttons will be activated.


>> 6. Batch size? What's that?

"Batch" is a jargon of deep learning.
Basically batch size means a degree of parallelisms to calculate neural network.
But currently it seems little performance boost. Please keep it as 1.


I hope that you will enjoy the app!

wineandgolover san,

Yes, "与围棋老师复盘" is a restricted version of "A Master of Go".
All features except for playing a game are completely same.

Lately when I directly click .sgf file on my iPad it opens 2 clients of A Master of Go in split-screen mode. Any idea how to disable this? (the app is always fully closed when I do this, I think the other screen is where I left the app last time I used it). It used to ask my "Do you want to abandon your current study?", but it does not do it anymore. I think this changed for me ~1 month ago.

TomiP san,

Thank you for using the app!

Since supporting multiple window, the behavior was changed.
When the last state of app is the state that main menu was opened on full screen, the app will open a file on full screen.
If the app is a state during playing or studying a game, the app will open a new window.

There is no options to disable it at present.

Thank you.

Some questions after stumbling over this program due to an advice in another thread:

1. Does Master of Go give you several choices (with % and playouts and colors for good (green) and not so good (red)) of moves like Lizzie?
2. Does Master of Go give u the chance to let AI play against itself, especially after loading a game to play for example AI vs. AI from move 15 on?
3. Is the AI stronger than Leela 20x256 (which I use right now)?
4. Are there any main differences between Lizzie/LZ (which I use now) and Master of Go?
5. The payment is 13 $, is it a one time payment and such one that you get all features at once?
