Cant get Poweshell to run Terminal with JDK-14

Cant get Poweshell to run Terminal with JDK-14

I tried most of the day… (and i am a professional programmer!)
newest JDK… proper path statement… javac -version says jdk-14

gradle installed too (and validated), and i didnt need to since i am using python

and all i get is the classic compile error.

Start run a match

and only one more day to enter… ha ha!

Ok… finally got it working…
JDK-14 does not update path or java_home
you will probably have to delete the path statements for oracle pointing to JRE in favor of one for JDK

many places set up Java_home so that %Java_home% will work in path
it doesnt (at least in win 10 my version)… the path has to be C:\Program Files\Java\jdk-14\bin

i have yet to find out how this affects other things on my system as the browers will no longer point to the JRE but to the JDK this way (i am presuming).

python scripts/run_match.py python-algo python-algo at least is running (SORT OF)

its now giving this
SAPlayer 1 python-algo: py : The term ‘py’ is not recognized as the name of a cmdlet, function, script file, or operable program. Check the

since i have yet to modify things, i dont know if this is normal…
sadly, i only have today to enter, and a fear no one will answer :frowning_face:

if anyone has in them to help, i would appreciate it…

Maybe something with you python version or the PATH to your python version is missing.

Can you call ‘py’ from powershell?

Hi
I have a path to the anaconda3 directory C:\Anaconda3\
and anaconda scripts C:\Anaconda3\Scripts

entering py

I could try to point a path to an envs python38 i have in my anaconda3 setup…
but it shouldnt be different since 3.8 is what i have upgraded everything to

thanks for the help!!!


#7

as a precaution i ran the following

conda update anaconda

conda install anaconda

conda update -n root conda

conda update --all

this actually updated things i somehow didnt have…
it didnt solve the problem, but i bet it stopped future problems before they occur

will keep trying…
thx

PS ad this to the list too
conda init powershell
[mine came up no change]

oh… typing python works fine… typing py does not

This should answer the question: https://stackoverflow.com/questions/50896496/what-is-the-difference-between-py-and-python-in-the-terminal

" py is the Python launcher which is a utility that comes with Python installations on Windows. It gets installed into C:\Windows\ so it’s available without requiring PATH modifications. The Python launcher detects what Python versions are installed on your machine and is able to automatically delegate to the right version. By default, it will use the latest Python version that is on your machine. So if you have installed 2.7, 3.5 and 3.6, running py will launch 3.6. You can also specify a different version by doing e.g. py -3.5 to lauch 3.5, or py -2 to launch the latest Python 2 version on your machine."

Regarding Anaconda: “those versions simply won’t be available through the Python launcher by default”

I think you have to install it separately to anaconda or figure out how to make your anaconda versions available to the Python launcher.


#10

Well,
at least people reading are learning a lot… :slight_smile:

will look into anaconda and the python launcher… its a thread to follow and unravel
what i find out, i will post like the other stuff…

thanks felix… you been awesome!!!


#11

Ok… got it to work… but boy did i read alot… (thanks felix)

there were several solutions that people had online.
one was to install another version of python, then get the py.exe, then uninstall (or leave the version)
i didnt like that…

then someone wrote a msi to install the py.exe
but given its an untrusted source…
i didnt like that

so i went with a way that no one suggested, but decided was the best (for me)
i went into the ps1 and changed

py -3 $algoPath
to
python $algoPath

if the only point of py is to run python, and all my versions were high enough
and the path to anaconda worked to run python, then just run python directly

i do not know if the upload uses the ps1 file…
if it does then it has to be switched back before cmpressing and upload
if not, then it doesnt matter… just use python over py -3

#12

I have not tested it, but I would guess that before you upload it the file run.ps1 has to be like that py -3 $algoPath to be able to work.

But as a workaround for local testing, I think it should be possible to modify the file scripts/run_match.ps1 to not call the original run.ps1 and instead call a differently named version of that file with your changes:
python $algoPath


#13

Either way will do… and its a lot easier to do that than to install a null version of python just to get py.exe
I also like it better as it is much higher security for my system… without py.exe a rogue python script can’t be run accidentally… given i sometimes have clients and they have security needs, this is a big plus in the long run.

i would suspect that the PS1 is not used by the C1 system to run, they would not need to
though running with python instead is a better thing than running with py - it should be the norm
it would work with all installations, not just if you did this through windows, which with anaconda and other recommendations on not letting installs update paths (and that unless you install for all users).

should be simple enough to test though…
Now i have to figure out how to compress… :smile:


#14

Ya we just use the run.sh because our servers are on linux.


#15

Call it an edumacated guess…
this would mean that bypassing py.exe is just fine, and the added trouble of changing before submission is not necessary… this may get more people to participate rather than having them give up fighting their own systems to get them to work…

hopefully this turns out to be a positive thread for many

thanls for the info C1Junaid!!!


#16

OK, I recently needed to reinstall the starter kit on a new windows environment … and this java problem gets me EVERY time. I don’t wanna thing how many new players give up on this step :frowning: .
The issue is like follows:

  1. Usually or by default, windows has Java 8 installed, and linked in the path.
  2. By following the installation guide to get Java 10, you end up installing 11+ as 10 is no longer supported.
    3a. Testing the starter kit, the gives version mismatch, that combined with the point above, can be easily confused that you did not installed the correct version …
    3b. You actually need 3 additional steps to make it work:
  • remove old versions of java,
  • add the new version to the path,
  • restart windows
    Missing any of them leads to frustrations big frustration with no clear warnings to follow on :slight_smile:

I was thinking this information in the git installation steps, as a Troubleshooting section …
when I found out that there IS already a the needed information … linked there.
May be adding a more detailed Troubleshooting section, with the specific use cases and how to proceed will save some new players. I can write it up, just not sure where is the best place to put it.

May be a forum post, to collect ALL common start up errors, with solutions (and we can build it and clean it up over time) then pin / link / extract it where needed.

#18

Hi Ryan…
what can i do to help from this post… as you can see, i avoided using windows because it was easier to just call python itself given my installs were all above the minimum… maybe we dont need py.exe anymore?

now my issue is figuring out how to run hundreds of rounds or a loop that can run hundreds so that its easier to write machine learning code using pytorch (or something similar)…

the more i play in this, the more it seems necessary to write my own game env - which would be a bear and annoying to keep up with what is done in the real game (and hard to match… but if they can remake final fantasy VIII, anything is possible… ha ha)

maybe im just too old having done this code stuff since the 1970s… :rofl::rofl::rofl::pray::pray:


#19

Demorf…
most of my issue with java was getting things to run off the JDK not the JRE… which really required the path statements to be fixed up after installing…

as far as getting it to run without py.exe (because i use anaconda), i just changed the py reference to python and removed the -3 in the powershell scripts…

as mentioned below… running a loop environment to do round after round after round is the next pain in the [censored]…
