Performing unit tests on remote machine when errors began occurring when running with Python 3.5.2 but not with Python 2.7.12.

train_output.txt and test_output.txt each contained:
/bin/sh: java: command not found

I adapted the java -jar v1-0.jar calls in boostsrl.py to have absolute paths based on where java was installed.

Unittests still took quite a while after command python3 tests/tests.py was ran, I killed it after waiting.

[hayesall@tank boostsrl-python-package]$ python3 tests/tests.py . ^CE.. ====================================================================== ERROR: test_boostsrl_testing (__main__.MyTest) Run the entire training/testing pipeline to ensure testing works properly. ---------------------------------------------------------------------- Traceback (most recent call last): File "./boostsrl/boostsrl.py", line 47, in call_process os.waitpid(p.pid, 0) KeyboardInterrupt During handling of the above exception, another exception occurred: Traceback (most recent call last): File "tests/tests.py", line 169, in test_boostsrl_testing results = f.test_testing_1() File "tests/tests.py", line 63, in test_testing_1 results = boostsrl.test(model, test_pos, test_neg, test_facts) File "./boostsrl/boostsrl.py", line 192, in __init__ call_process(CALL) File "./boostsrl/boostsrl.py", line 49, in call_process raise(Exception('Encountered problems while running process: ', call)) Exception: ('Encountered problems while running process: ', '(cd boostsrl; /usr/bin/java -jar v1-0.jar -i -model train/models/ -test test/ -target cancer -trees 10 -aucJarPath . > test_output.txt 2>&1)') ----------------------------------------------------------------------

Checking boostsrl/test_output.txt revealed a lock was created on aucTemp.txt

After removing the lock, I was able to run training, but auc calculation still crashed.

./run.sh: line 1: java: command not found

If this errors out you did not install «java» and the program depends on it.

sudo apt-get install openjdk-8-jre 

would install Open JDK 8 and make the script work.

sudo apt-get install openjdk-6-jre sudo apt-get install openjdk-7-jre 

for version 6 or 7 but 8 should be the best one.

For Ubuntu 14.04 you will need

sudo apt-get install openjdk-6-jre

I’m trying to install worksnaps client so I can start working on a project. I’m running Ubuntu 14.04 LTS 32bit system. Installation and Configuration for worksnaps are simple :

Download the Worksnaps Client package. The package is in zip format. With the user login that is going to use the Worksnaps Client, run the command «unzip WSClient_linux_.zip» to unzip the package. You should be able to see a directory «Worksnaps» created. Execute command «cd Worksnaps/bin» Execute command «chmod +x run.sh» Execute command «chmod +x p.sh» Launch the Worksnaps Client by executing command «./run.sh» (Note: please do not click any Jar file to launch the program.)

./run.sh: line 1: java: command not found 

Link to the instruction’s for worksnaps .They said here Worksnaps client version 1.1.20140511 or newer runs on both 64-bit or 32-bit Java environment. On a 64-bit Linux system, 64-bit Java environment is preferred. But they are not specific about what version does not working, I assume you can install both on 32-bit and 64-bit system, and there is just one version to download `worksnaps verison 1.1.201440511′. Can someone help me overcome this.

bukkit_start.sh: line 3: java: command not found

OK. I would recommend that you install the sun jre.

To do this you need to enable non-free repositories.

You need to add these to your sources file (use whatever editor you like, I use nano):

deb http://ftp.debian.org/debian/ squeeze contrib non-free deb-src http://ftp.debian.org/debian/ squeeze contrib non-free deb http://security.debian.org/debian/ squeeze/updates contrib non-free deb-src http://security.debian.org/debian/ squeeze/updates contrib non-free

Then save the file, (Ctrl+O in nano).

apt-get update apt-get install sun-java6-jre

i get this after trying to update i get this

Reading package lists. Done Building dependency tree Reading state information. Done Package sun-java6-jre is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package sun-java6-jre has no installation candidate

and some of those links dont work tried it when updated

Did you do the apt-get update ? I misspelled it in my above post. If so, not sure what the issue is. I just tried this on my squeeze server and it worked.

Как прописать путь до Java в исполняемом файле .sh

Добрый день форумчане, на Ubuntu 20.04 есть приложение которое использует Java 8, запускается оно через файл start.sh в котором прописаны конфиги, на самой машине пришла необходимость по умолчанию использовать Java 16. Теперь приложение которое использует Java 8 по умолчанию обращается через Java 16, как правильно в файле start.sh прописать чтобы это приложение использовало Java 8?

P/S Погуглив везде рассказывают о том как установить определённую Java по умолчанию или для определённого пользователя.

Ты можешь напрямую дёргать бинарь java:

#!/bin/sh /usr/local/openjdk8/bin/java -jar ./path/to/your.jar $* 

Пути поправишь как надо, в Ubuntu они другие.

Разве эта переменная не для обёртки-«переключателя» java?

Стандартов тут нет, поэтому универсальный ответ — изучай файл start.sh и разбирайся, как там устроен поиск java.

Обычно используют JAVA_HOME, если он не задан, то ищут java в $PATH . Поэтому для надёжности можно сделать так:

export JAVA_HOME="xxx" PATH="$JAVA_HOME/bin":$PATH ./start.sh 

Скорей всего этого хватит. Может быть и одного из этих пунктов хватит.

У меня установлена Java 8. С ней падает лаунчер Minecraft на процессорах AMD Athlon II, Phenom II и AMD FX. Падает с ошибкой Webkit, а вернее библиотеки из состава Java, реализующей отображение веб-контента.

То же самое с Java 7. Только с Java 6 лаунчер нормально работает.

#!/bin/sh /home/zenitur/bin/jre1.6.0_45/bin/java -jar /home/zenitur/bin/launcher.jar 

А сама игра запускается с Java 8 (можно в настройках профиля указать путь к Java 8, но по-моему там изначально так и было).

Просто замени в скрипте путь к бинарнику Java, укажи конкретно путь к Java 8.

Дак в том то и вопрос поста, как правильно это прописать)

В скрипте, скорее всего, просто бинарник «java» вызывается. Заменяшь «java» на «/usr/lib/jvm/java-8-openjdk/jre/bin/java», или где у тебя там Java 8 лежит. Готово.

Так вроде получилось, благодарю!
