Rocket U2 | UniVerse & UniData

Rocket U2 | UniVerse & UniData Hi allI have some problems when connecting to servers using uopy, as the PATH variable is wrong.From the terminal console:>SH -c "echo $PATH"/usr/local/bin:/usr View this on Rocketsoftware >

I have a variable defined in /etc/environment:

[hcortiguera@catalogo20 ~]$ cat /etc/environment
OPENAI_API_KEY=MY_API_KEY

I can read it from command-line Python:

[hcortiguera@catalogo20 ~]$ /u2/uv/python/bin/python3
Python 3.9.2 (default, Jun 15 2021, 01:30:50)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-36)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.environ['OPENAI_API_KEY']
'MY_API_KEY'

But I can't read it when I call Python from BASIC

NOMBRE.VAR.ENTORNO='OPENAI_API_KEY'

NOMBRE.SCRIPT='consultaVariableEntorno'
NOMBRE.FUNCION='get_var_entorno'

RESPUESTA=PyCallFunction(NOMBRE.SCRIPT,NOMBRE.FUNCION,NOMBRE.VAR.ENTORNO)
CRT '[EJECUTADO]'
CRT '[':RESPUESTA:']'

The Python code:

import os

def get_var_entorno(var_entorno):
    return str(os.environ.get(var_entorno, '?'))

The output from BASIC:

[EJECUTADO]
[?]

Why the Python interpreter is not reading /etc/environment?

Héctor,

I assume you are trying to set up a virtual python environment.  I have not tried that myself, but believe the issue is the difference between the Client connection you are making with uopy and the python used on the server.

uopy is client based, while u2py is the server side module used to interact with UniData/UniVerse,  once you start a U2 connection, any calls to Python will use the Version of Python set up for the U2 server.  This information is in .pyconfig file.

IE:  for my laptop on UniData on Windows it is at C:\\U2\\ud83\\.pyconfig

and contains:

PYHOME=C:\\U2\\ud83\\Python
PYLIB=C:\\U2\\ud83\\Python\\python311.dll

---

Note that if you connect to U2 with uopy, and then have a Basic program call Python, it will be the server side python that will be used, and not the client side python, which could be on a different server.

Hi Mike

I tried putting some variables into .pyconfig, but then the execution fails.

cat /usr/uv/.pyconfig
