Stockfish: Cannot start fishtest cmd

[Nordlandia]

I've created account and followed everything per "Running the worker on Windows"

Once i launch fishtest.bat cmd opens for about 200ms then close.

I really want to contribute CPU time.

Unfortunately, I currently do not know what could cause this. @ppigazzini Do you have an idea?

[ppigazzini]

I just installed multivariant fishtest in a clean Windows 10 64 bit virtual machine following step-by-step the wiki: it works.

1. check the username password with a login in the page New Test
2. if username and/or password have some special characters, write they within a couple of double quote:
   cmd /k C:\Python27\python.exe -i C:\fishtest-master\worker\worker.py --concurrency <n_cores> "<username>" "<password>"
3. open a cmd prompt, then copy&paste the first line of the bat file, then copy&paste the second line without cmd /k. In this way the prompt should rest open after the error

[ianfab]

@ppigazzini Thanks a lot.

[Nordlandia]

The system can not find the path specified.

msys64 and fishtest-master is stored in C drive. Something is wrong.

[ppigazzini]

@Nordlandia The batch expects to find these files:

1. C:\Python27\python.exe
2. C:\fishtest-master\worker\worker.py
3. C:\msys64\mingw64\bin\g++.exe

I got your error message only if I write a wrong path for python, so check to have C:\Python27\python.exe or change the path according your python 2.7.x installation.

If you are contributing also in official fishtest be sure that C:\fishtest-master\ is the path for multi variant fishtest, or change the path accordingly.

[Nordlandia]

I'm using Fishtest-Worker-Portable for official fishtest, runs without problems.

Someone create _Portable_ worker for variant as well and nobody has to experience this.

Are you sure https://github.com/ianfab/fishtest/archive/master.zip isn't corrupted?

[ppigazzini]

@Nordlandia you have not answered the questions about:

1. your python path installation: from your error message it seems not in C:\Python27\python.exe
2. if C:\fishtest-master\ is the path of your multi variant fishtest installation

If you have a custom python path installation, update the startup batch file. A space in the path is a problem, you should write this:

cmd /k ""C:\Your Python27 path\python.exe" -i "C:\Your fishtest-master path\worker\worker.py" --concurrency 3 "<username>" "<password>""

Off-topic: I like only short and well documented installer:

1. provide simple know how to the user
2. only one installation of the tool chain packages (python, msys, mingw-w64) to run both official and multivariant fishtest (simply use two startup batch files)
3. easier to keep updated the packages

I updated the wiki page with some disclaimer about using the default setting during installation.

C:\Python27\python.exe is in root folder in C drive (first folder)
C:\fishtest-master\worker\worker.py same as above
C:\msys64\mingw64\bin\g++.exe same as above

I convert text file into bat then paste everything below and saves, doesn't work.

Launching the worker

@echo off
SET PATH=C:\msys64\mingw64\bin;C:\msys64\usr\bin;%PATH%
cmd /k C:\Python27\python.exe -i C:\fishtest-master\worker\worker.py --concurrency

[ppigazzini]

Yes, the bat content should be in your case (I'm supposing: concurrency=3, nordlandia as username and your_password as password)

@echo off
SET PATH=C:\msys64\mingw64\bin;C:\msys64\usr\bin;%PATH%
cmd /k C:\Python27\python.exe -i C:\fishtest-master\worker\worker.py --concurrency 3 "nordlandia" "your_password"

It seems that "--concurrency 3" solved the issue.

--concurrency is not correct prefix on my end.

Remove "" solved the issue for me.

Is it possible to contribute towards TwoKings?

[ianfab]

@Nordlandia Nice to hear that it is working now. There currently is no way to restrict contribution to specific variants, it will pick any task that is to be processed.

Thanks @ppigazzini for your help.

[ppigazzini]

Wiki page updated writing more clear installation instructions.
Added also the instruction to write a custom_make.txt file to have faster binaries with a recent CPU (Intel Haswell or later).

@Nordlandia: IIRC your 7 cores worker is a i7-5960X (Haswell-E). For that worker you can write a C:\fishtest-master\worker\custom_make.txt file with this text [text edited to correct a mistake]:

make profile-build ARCH=x86-64-bmi2 COMP=mingw -j 7

[ppigazzini]

@Nordlandia: sorry for my typo. For your worker with i7-5960X (Haswell-E) you can write a C:\fishtest-master\worker\custom_make.txt file with this text:

make profile-build ARCH=x86-64-bmi2 COMP=mingw -j 7
