I'm trying to execute a python script (3.6.5) which is located in one folder inside my Laravel app folder. The script is been called from a controller and retrieves the output of the scrpit. I'm using Symfony/process to execute the scrip, like in the code below:
public static function searchAnswers($input)
{
$process = new Process(array('dir', base_path() . '/app/SearchEngine'));
$process->setWorkingDirectory(base_path() . '/app/SearchEngine');
$process->setCommandLine('python3 SearchEngine.py ' . '"'. $input .'"');
$process->setTimeout(2 * 3600);
$process->run();
if (!$process->isSuccessful()) { //Executes after the command finishes
throw new ProcessFailedException($process);
}
$list_ids = array_map('intval', explode(' ', $process->getOutput()));
info($list_ids);
$solicitations = Solicitation::join('answers', 'solicitations.id', '=', 'answers.solicitation_id')
->whereIn('solicitations.id', $list_ids)
->limit(20)
->get();
info($solicitations);
return $solicitations;
}
In my localhost, the script is been called with no issues, either from my terminal or from my running application via HTTP requests. But, after I uploaded my app version to my remote server, which is Debian, I'm getting the following exception:
"""

The exception points out to errors of import in the python script. But, when I execute the script from the terminal in the remote server either directly or by Artisan commands, everything works fine. Any ideas of what is happening?
Thanks in advance!
