The invention and popularization of Large Language Models (such as OpenAI's GPT-4) has launched a wave of innovative solutions that can leverage large volumes of unstructured data that was impractical or even impossible to process manually until recently. Such applications may include data retrieval (see Don Woodlock's ML301 course for a great intro to Retrieval Augmented Generation), sentiment analysis, and even fully-autonomous AI agents, just to name a few!

Question Ivan Tioh · Apr 5, 2017

I have done Python - Cache binding setup following the guide from http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY…. I have also run test.py from sample3 folder and it able to run and complete successfully.

However, when I try to run the same test.py code via $zf, it gives error with exit code 1.

I've tried running help("intersys.pythonbind3") via $zf and also running from Cache terminal as follows:

  1. $zf(-1,"C:\Python36\python <path>/script.py")
  2. ! C:\Python36\python <path>/script.py

which gives me the following output:

problem in intersys.

Question Steve Pisani · Jan 29, 2022

Hi,

What is the Python syntax I can use from a ClassMethod (developed in an IRIS using embedded Python), in order to invoke another class method,

- in the same class; and

- in another class.

I see 'self' is synonymous to use $this (..) in ObjectScript, but these are ClassMethods I am invoking, and self did not seem to work.

thanks - Steve

Note from Author
Since writing this article InterSystems has introduced native support for the OpenTelemetry standards with IRIS 2025.1.  Whilst this article helps to articulate how IRIS and Python can be used to extend IRIS's native capability, if you are specifically looking to implement OpenTelemetry, please head to this article developed by my colleague @Luis-Ángel.Pérez-Ramos: 

 

A customer recently asked if IRIS supported OpenTelemetry as they where seeking to measure the time that IRIS implemented SOAP Services take to complete.

This formation, accessible on my GitHub, will cover, in half a hour, how to read and write in csv and txt files, insert and get inside the IRIS database and a distant database using Postgres or how to use a FLASK API, all of that using the Interoperability framework using ONLY Python following the PEP8 convention.

This formation can mostly be done using copy paste and will guide you through everystep before challenging you with a global exercise.
We are available to answer any question or doubt in the comment of that post, on teams or even by mail at lucas.enard@intersystems.com .

Since I saw many posts on Developer Community related to Python, and the very good articles and application written by @Eduard Lebedyuk I was wondering: "As a Object Script developer, why would I want to use an other  language in Object Script? If I ever need to execute something in Object Script, I would do it in Object Script!".

I thought those functionalities to use other languages in Object Script were made only for other languages developers who have to write Object Script code.

Recently I had to parse a huge CSV file : 1.7Gb and more than 5 millions lines.

While starting the development with IRIS we have a distribution kit or in case of Docker we are pulling the docker image and then often we need to initialize it and setup the development environment. We might need to create databases, namespaces, turn on/off some services, create resources. We often need to import code and data into IRIS instance and run some custom code to init the solution.

And there plenty of templates on Open Exchange where we suggest how to init REST, Interoperability, Analytics, Fullstack and many other templates with ObjectScript. What if we want to use only Python to setup the development environment for Embedded Python project with IRIS?

So, the recent release of Embedded Python template is the pure python boilerplate that could be a starting point for developers that build python projects with no need to use and learn ObjectScript. This article expresses how this template could be used to initialize IRIS. Here we go!

We are happy to share interesting information with you, as well as tell you why Python is good, where it is used.

Among the most used libraries are NumPy and Pandas. NumPy (Numerical Python) is used to sort large datasets. It simplifies mathematical operations and their vectorization on arrays. Pandas offers two data structures: Series (a list of elements) and Data Frames (a table with multiple columns). This library converts data into a Data Frame, allowing you to remove and add new columns, as well as perform various operations.

Question David.Satorres6134 · Jul 3, 2019

Hello all,

We recently moved our workstations to Windows 10 and so we updated all our local installations to IRIS (servers already run IRIS 2019.1). Now we are trying to connect our pyCharm to IRIS but we can't succeed.

In our ancient Ensemble installation we used intersys.pythinbind3 system, but I realized that with IRIS this is not provided. So I finally found the Welcome to Python QuickStart page (https://learning.intersystems.com/course/view.php?id=1113&ssoPass=1) and I'm trying to connect using pyODBC.

This is a translation of the following article. Thanks [@Evgeny Shvarov] for the help in translation.

This post is also available on Habrahabrru.

The post was inspired by this Habrahabr article: Interval-associative arrayru→en.

Since the original implementation relies on Python slices, the Caché public may find the following article useful: Everything you wanted to know about slicesru→en.

Note: Please note that the exact functional equivalent of Python slices has never been implemented in Caché, since this functionality has never been required.
And, of course, some theory: Interval treeru→en.

All right, let’s cut to the chase and take a look at some examples.

In the previous articles, we learned the basics of using IMAP protocol to handle messages from mailboxes in an e-mail server. That was cool and interesting, but you could take advantage of implementations created by other ones, available in libraries ready to use.

One of the improvements to the IRIS data platform is the ability to write Python code alongside ObjectScript in the same IRIS process. This new feature is called Embedded Python. Embedded Python lets us bring to our ObjectScript code the power of the huge Python ecosystem’s libraries.

Question Mads Lien · May 8, 2019

Hi

I am working with a Caché system with a Python binding and big datasets in health care. I am using the Python library Pandas and Jupyter notebook for data manipulation and often special modules for different projects, including different versions of Python. To keep the environments separated, I have been testing Docker, but I am at loss on how to install the Python binding. Has anyone any experience with this? Or better yet, a Docker image that has the binding installed?

I am also considering that Docker might not be the suitable for this situation and I am grateful for any thoughts on this.

I am documenting a demo of InterSystems IRIS featuring Embedded Python and Jupyter Notebook deployed on the same container, and an Embedded Python application developed on that Jupyter Notebook IDE.

I have used the Docker container created by @Bob Kuszewski as a development environment to demonstrate how Embedded Python app can be developed in such a setting to push and retrieve data to and from InterSystems IRIS. The benefit of using this container as the development environment is that it is a virtual environment with Jupyter IDE and IRIS connected and running side by side.

i tried the following but i'm wondering if this is the most efficient way?

to run the stored procedure as %ResultSet inside cache in a classmethod and serialize the data to JSON

and then call that class method from python

The aim of this proof of concept is to show how the gRPC protocl can be implemented with the IRIS ineroperabilty module.

On this schema, we can see that the gRPC Service is hosted by IRIS.

This service must invoke the IRIS interoperability module. For that it transforms the protobuf messages to IRIS messages.

The gRPC client is host by a Flask server for demo purpose, the gRPC client can also be invoke by the python script.

Why am I writting this?

Last year I made an article for starters on using embedded python. Later, it started a little discussion on how to return values with python and I found some interesting observations that are worth writing a little article. Also, hopefully I can reach more people by writing this.

 

Possible situations

There are two things you'll need to care about when returning a value with python. The first is the type you're trying to return and the second is where you're returning it.

I'm proud to announce the new release of iris-pex-embedded-python (v2.3.1) with a new command line interface.

This command line is called iop for Interoperability On Python.

First I would like to present in few words the project the main changes since the version 1.

A breif history of the project

Version 1.0 was a proof of concept to show how the interoperability framework of IRIS can be used with a python first approach while remaining compatible with any existing ObjectScript code.

What does it mean? It means that any python developer can use the IRIS interoperability framework without any knowledge of ObjectScript.

Example :

from grongier.pex import BusinessOperation

class MyBusinessOperation(BusinessOperation):

    def on_message(self, request):
        self.log.info("Received request")

Great, isn't it?

Question Emmanuel Vanlaar · May 24, 2020

Hi,

I was playing around with the python binding for caché (2018.1.4) and I ran into some problems.

When executing the class query "List" from SYS.Database the  pythonbind interface throws an exception, that seems to be caused by a mismatch of the defined SQL datatypes for this query and what is actually returned (or the lack of type conversion in the pythonbind interface).

Is this a known issue ? Are there solutions/workarounds for this,
Or is this a bug ?
 

The details:

When executing "List" from SYS.Database there is an error for every datarow fetched.
When executing "FreeSpace" from SYS.
