QUESTION
I have a standard Maven project and I want to run the meTypeset script. This script takes 3 args where the second one is a file and the third one is a folder created as output.
This is how the script runs in a cmd:
...ANSWER
Answered 2021-Feb-08 at 09:30Unlike python Java may need some help. Do I guess correctly you are running on Windows?
You invoke the Runtime.exec() method. The method returns a Process instance, and in it's documentation you can read
By default, the created process does not have its own terminal or console. All its standard I/O (i.e. stdin, stdout, stderr) operations will be redirected to the parent process, where they can be accessed via the streams obtained using the methods getOutputStream(), getInputStream(), and getErrorStream(). The parent process uses these streams to feed input to and get output from the process. Because some native platforms only provide limited buffer size for standard input and output streams, failure to promptly write the input stream or read the output stream of the process may cause the process to block, or even deadlock.
So it is likely your process is started by the OS but gets blocked due to I/O restrictions. Get around that by reading the STDOUT and STDERR streams until your process finishes. One good programming model is visible at https://www.baeldung.com/run-shell-command-in-java
QUESTION
I created a Dockerfile and then built it for my team to use. Currently I am pulling from the CentOS:latest image, then building the latest version of Python and saving the image to a .tar file. The idea is for my colleagues to use this image to add their Python projects to the /pyscripts folder. Is this the recommended way of building a base image or is there a better way I can go about doing it?
...ANSWER
Answered 2020-Jun-16 at 16:55Yes this is the standard and recommended way of building a base image from a parent image (CentOS in this example) if that is what you need Python 3.8.3
(latest
version) on CentOS system.
Alternatively you can pull a generic Python image with latest Python version (which is now 3.8.3
) but based on other Linux distribution (Debian) from Docker HUB repository by running:
QUESTION
Attempt to call python function from scala fails with below error. But works fine when the same command is invoked directly from command line.
Please find below simplified code snippets :-
greeting.py
...ANSWER
Answered 2020-May-18 at 21:14It works from the command line because the shell is parsing and interpreting the string before invoking the python
command. In the Scala code the ProcessBuilder
is trying to parse and interpret the string without the shell's help.
We can help the interpreting. This should work.
QUESTION
I have UniVerse 11.3.1, and have been taking advantage of Rocket's u2py
module to run python code. Overall, this has been great. When calling python code from PICK I usually do PyCallFunction
. However I have a number of scripts I run directly from the RUNPY
command in TCL.
In refactoring some of my directories I am moving away from having the PP
directory house my python code. I can call my scripts from a new directory, say PYSCRIPTS
, but it means if I have a bash or TCL script that calls RUNPY
I now have to explicitly call out which directory I call it from:
RUNPY PYSCRIPTS test.py
instead of RUNPY test.py
.
Is there a way to change the default directory that RUNPY
looks in? Is this related to PYTHONPATH configuration, or is this hard-coded in the UniVerse binary? A minor inconvenience, but I would rather handle the parent directory of these scripts via configuration vs hard-coding them.
ANSWER
Answered 2020-Feb-19 at 18:38The crusty old UniVerse guy in me says use a VOC entry, but that will only work in the Account you put it in.

Answered 2020-Jan-05 at 03:31You should replace this with the version with the full path to the python interpreter, because whatever is run from the cron
lacks the "usual" environment variables setup, namely, PATH is what you're missing the most:
QUESTION
My Raspberry Pi hosts a MySQL database. When my Pi starts it runs a python script which writes to the database. The script writes the date, time and IP address to the database.
The python script to do this runs perfectly when running it from the terminal. However when I try and run the python script on startup nothing happens. Creating a cronjob to run the python script showed me an error was being produced saying : "ImportError: No module named mysql.connector"
I'm just not sure why the script isn't working properly from startup when it works If I manually run it.
I have tried runnning the script directly from : /etc/rc.local running as :
...ANSWER
Answered 2019-Jun-02 at 05:48It seems that when you run your script as a cronjob it can't find the correct PYTHONPATH
. First, find your module path with the below script:

QUESTION
I want to invoke a python script in a js file using python-shell. However the script requires python3 and py2 is always used, while my local development has both py2 and 3 installed. How do i specify it to use python3 instead?
...ANSWER
Answered 2018-Jan-25 at 05:39According to the python-shell documentation, you can specify the python interpreter path in the PythonShell
options. There are two things you need to do:
- Ensure that python3 is installed on your local system (might need
pip install python3
or something similar) - Change the python path to point to python3 (might just need to be
/usr/bin/env python3
EDIT: In response to your edit, if both of your node services are running on Linux, you should be able to use /usr/bin/env python3
. See this stackoverflow question for resolves across systems.

Install pyscripts
You can use pyscripts like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
