Question Kurro Lopez · Mar 16

Hi all.

I have a rather strange problem.

I've created a method in Python to create a vector for a vector search. So far, so good.

If I call this method from the terminal, it works correctly:

But if I make this same call from a code block in a Business Process, it gets stuck, doesn't respond, and throws the following error:

Does anyone know what's happening and how to fix it?

Thank you in advance

I am trying to add Plotly Bar graph in a div to a CSPpage. I am working in IRIS 2022.1. I created persistent class.

I copied relevant code into github repo:

oliverwilms/iris-python-plotly
 

iris-python-plotly/csp/otwPlotly.csp at master · oliverwilms/iris-python-plotly
 

Set tPlotlyDiv = ##class(dc.python.test).PlotlyDiv(trnYear,trnMonth)

ClassMethod PlotlyDiv(pTrnYear = 2025, pTrnMonth = 8) As %String
{
    Set importlib = ##class(%SYS.Python).Import("importlib")
    Set plotdiv = ##class(%SYS.Python).Import("plotdiv")
    Do importlib.reload(plotdiv)
    Set div = plotdiv.

I’ve been exploring options for connecting Google Cloud Pub/Sub with InterSystems IRIS/HealthShare, but I noticed that IRIS doesn’t seem to ship with any native inbound/outbound adapters for Pub/Sub. Out of the box, IRIS offers adapters for technologies like Kafka, HTTP, FTP, and JDBC, which are great for many use cases, but Pub/Sub appears to be missing from the list.

Has anyone here implemented such an integration successfully?

For example:

  • Would it make sense to leverage IRIS’s Business Service + REST API adapter to connect to Google’s Pub/Sub REST endpoints?

I have a custom Buffer class which is designed to capture written/printed statements to the device, to be able to transform the captured text to string or stream type. I have used this in ObjectScript to capture ObjectScript write statements and return a string. I would like to try to use this with a [ Language = python ] method as follows. This class will be called by a scheduled task.

/// ObjectScript code which initializes buffer to capture statements written in nested method call
ClassMethod CollectStringFromBuffer() 
{
    set buffer = ##class(CustomClass.Buffer).%New()
    do buffer.

I am brand new to using AI. I downloaded some medical visit progress notes from my Patient Portal. I extracted text from PDF files. I found a YouTube video that showed how to extract metadata using an OpenAI query / prompt such as this one:

ollama-ai-iris/data/prompts/medical_progress_notes_prompt.txt at main · oliverwilms/ollama-ai-iris
 

I combined @Rodolfo Pscheidt Jr https://github.com/RodolfoPscheidtJr/ollama-ai-iris with some files from @Guillaume Rongier https://openexchange.intersystems.com/package/iris-rag-demo.

I attempted to run

Question Kunal Tiwari · Jul 10, 2025

Hello,

I'm trying to connect a Python backend application to an InterSystems IRIS Community Edition instance running in a Docker container on an AWS EC2 instance. I'm facing persistent connection issues and an SSL Error despite the Superserver apparently having SSL disabled. I'm hoping for some insight into what might be causing this contradictory behavior.

My Setup:

  • InterSystems IRIS: Community Edition (Docker image intersystems/iris-community:2025.1)
  • Deployment: AWS EC2 (Ubuntu) instance.
  • Port Mapping: Host port 9091 mapped to container port 1972 (Superserver).

I'm trying to deploy a python/flask application to an Iris4Health container (2025.1) but running into some issues with packages and where they should be installed. 

First one if the flask packages themselves. I tried to installed the flask packages into the python external language server virtual environment, but even doing this when configuring the WSGI application in the web application section, it would complain about not having a WSGI framework. Once I created a custom container and added the flask package at the OS level, I was able to configure the web application without it complaining.

Hi Guys,

I'm a newbie running IRIS in a container (IRIS for UNIX (Ubuntu Server LTS for x86-64 Containers) 2024.3 (Build 217U) Thu Nov 14 2024 17:30:43 EST) and trying to setup Python so I can start working on ML & Autosklearn,my understanding is that IRIS already comes with embedded Python but unable to do something like "import pandas as pd"  in VSCode which looks like I need install a more complete version of Python or packages, so what I'm missing?

I combined @Rodolfo Pscheidt https://github.com/RodolfoPscheidtJr/ollama-ai-iris with some files from @Guillaume Rongier https://openexchange.intersystems.com/package/iris-rag-demo.

My own project is https://github.com/oliverwilms/ollama-ai-iris

I can run load_data.py and it connects to IRIS (same container).

When I try to run query_data.py https://github.com/oliverwilms/ollama-ai-iris/blob/main/query_data.py , it cannot connect to ollama:

ConnectionError: Failed to connect to Ollama. Please check that Ollama is downloaded, running and accessible.

I wonder if I need to add in query_data.

I read the article by @Rodolfo Pscheidt Jr:

https://community.intersystems.com/post/ollama-ai-iris

I forked his app and copied selected files from @Guillaume Rongier iris-rag-demo to make it containerized:

ollama-ai-iris/test_conn.py at 3da62770a90e34eff92241abbfc4f2c2a7027898 · oliverwilms/ollama-ai-iris
 

I struggle to understand what each element is or I do not understand why the code does not work:

url = f"iris://teste:teste@localhost:51774/TESTE"
 

Is teste:teste refer to username / password? I tried _SYSTEM:SYS

Is 51774 webserver port? Is TESTE namespace?

Question Timothy Leavitt · Mar 31, 2025

I'm exploring this right now: given a bunch of types defined as Pydantic models, how can I come up with an equivalent %RegisteredObject/%SerialObject and convert to/from (e.g., to support persistence and match validation as much as possible)?

People who know Python better than I do (e.g., your average undergraduate from this decade): is this a stupid idea or a cool idea? Has anyone else done this before?

Question Kurro Lopez · Mar 25, 2025

Hi all.

I'm trying to create an indexed table with an vector field so I can search by the vector value.
I've been investigating and found that to get the vector value based on the text (token), use a Python method like the following:

ClassMethod TokenizeData(desc As %String) As %String [ Language = python ]
{
    import iris
    # Step 2: Generate Document Embeddings
    from sentence_transformers import SentenceTransformer

    model = SentenceTransformer('/opt/irisbuild/all-MiniLM-L6-v2')

    # Generate embeddings for each document
    document_embeddings = model.

I have a flask application, its working locally. I also have a iris for health 2024.3 docker container front-ended with the iris nginx container.

I can configure the WSGI application with iris for health, give it a "url" (/flask or /csp/flask) but I cannot access the flask application. It looks like the url is not found within the nginx configuration. Is there any documentation or suggestion for configuration/enabling a flask app with a IRIS container front ended with the nginx container (provided by intersystems container registry)

Hello,

When setting up a new web app in iris (iris is in a container) iris complains that a WSGI framework is not installed. I have installed python into the container as well as both flask and django via the python virtual environment (see second screenshot) and the python language server is running

Is this the wrong way to install flask? How do I get the container version to recoginize that flask is installed?

Question Phillip Wu · Jan 28, 2025

Is it possible to get the length of queue for a production using Python code?

I'm using embedded Python at the moment.

I'd like to use the Python external language server later - the Python external server will not start in my environment.

If it is possible to query the production queue length programmically, please advise how?

It would also be nice to show the number of messages processed per second, if IRIS keeps track of this.

Question Dmitrij Vladimirov · Nov 22, 2024

Hence the question: is there a way to do that?
The goal is to get data (from half a thousand to 3-4 thousands lines) from DB, calculate standart deviation  then use it as logical condition in analyzer. 
For example IF std > custom_value = show_the_result ELSE null
There is a STDDEV(MDX) method used in Analyzer but it is a measure and it can not be used as logical condition (correct me if i am wrong)

And there is a Embedded Python with numpy, but logic behind STDDEV(MDX) and numpy.

This is for IRIS For Health 2024.2.0

We are migrating away from the .NET Gateway and trying to use the python integration instead.

I followed the instructions to install IRIS

Then I installed python following the IRIS documentation indicating that python should be installed globally.

I set up the PythonRuntimeLibrary and PythonRuntimeLibraryVersion options under System->Configuration->Advanced memory settings and when I run the shell function, I get python:

USER>do ##class(%SYS.Python).Shell()

Question David.Satorres6134 · Sep 2, 2024

Hello,

I've recently updated the python version of a linux server running Red Hat Enterprise Linux 8.10 (Ootpa). We have an instance 2023.1 running there, and whenever I run the $System.Pyhthon.Shell() I can see it's still pointing to the old version. From within linux, it runs the latest one (we've change all the links to the new 3.11, so no scripts are broken).

So I guess the problem comes from the fact irispython is still compiled using old python version. So, how can I do to force IRIS to use the current version on the server, or update the irispython file?

Thanks!
