Embedded Python refers to the integration of the Python programming language into the InterSystems IRIS kernel, allowing developers to operate with data and develop business logic for server-side applications using Python.
In ObjectScript there is neat option to log errors - call Log() method of an exception intance, e.g.:
ClassMethod MyMethod() {
Try {
w1/0
}
Catch e {
do e.Log() // logging error in the app logwrite"the error happened: "_e.DisplayString()
}
}
Is there anything like that for Embedded Python? e.g:
ClassMethod MyMethod() [Language = python] {
try:
print(1/0)
except ZeroDivisionError as e:
// how can I log e into IRIS App Error Log here?
print("Caught exception: " + str(e))
}
I have an Embedded Python method, which is essentially a call to one third-party module.
Most of the time, the method takes <0.1 seconds to execute, but sometimes it takes 30 or 60 seconds.
The server is relatively idle (20-30% CPU load).
How can I debug this issue further? Ideally, I want to know where this library spends the time. The library is mainly Python code (it's boto3, so it's not a Python C API proxy library).
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.
I am looking to create a Python virtual environment (venv) so that my imported/installed python packages can be separate on different namespaces in IRIS. I am able to go and create an environment, activate it, and install packages, but I am not sure how to ensure that Embedded Python methods actually point to this virtual environment.
Is the best solution to just load the virtual environment at runtime, in each method? That seems like a bad solution. Has anyone run into this and found a good solution?
I was wondering what best practice was for using macros in Embedded Python, i.e. iris.execute('$$$MACRO()') or something else. Does anyone have insight into this?
I got the PROTECT error while running functions. But, I could able to call the classmethods and methods in class definition with classMethodObject, classMethodValue etc.. from python. without any errors python code
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?
Just curious what the process is for debugging either a .py file that is uploaded to a specific namespace/location or a python classmethod defined in a .cls file.
My method can be run via the "Debug" breadcrumb but it doesnt hit breakpoints it just runs without a debugger. Also objectscript methods debug correctly
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?
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:
If anyone has experience debugging Embedded Python or has insight into why an ObjectScript method when called from a Python method would not work but would work when called directly via ObjectScript or in a Python shell, your help would be appreciated!
We have an ObjectScript ClassMethod called GetTemplateString() which takes in a templateName of String type and uses the template name to get the template object, access the Code, and read the code into a templateString. The string version of the Code is returned.
Recently, I've been working on a Business Process that processes a large JSON FHIR message containing up to 50k requests in an array within the JSON.
Currently, the code imports the JSON as a dynamic object from the original message stream, obtains an iterator from it, and processes each request one at a time in a loop.
I'm trying to convert a python dictionary into an objectscript array but there is an issue with the 'arrayref' function, that is not working as in the linked example.
I'm currently facing an issue with a Python script in my IRISHealth environment and would appreciate your insights.
I've written a class method, `getTokenCount`, in Python, which uses the `tiktoken` module. However, when I run the script in the terminal using `do ##class(python.openaiUtils).getTokenCount("")`, I encounter the following error:
MIRROR is the best solution for almost immediate replications to a Failover Server. The related mechanics are based on Global Journaling.
Globals hold Data and Classes and Routines and more ... If Mirroring is in place all is in sync. With minimum delays This is of course rather useful for code changes in Classes, Routines, ....
To what extent is Embedded Python covered by Mirroring? Or: What is required to Synchronize EmbeddedPython like Mirroring.
With ECP we have the option to have a collection of Frontend instances All Frontend servers typically have a common Master in the background Concentrating data on the Master server is the primary goal.
As a side effect, this applies also to Classes, Routines, .. anything stored in Globals. This is probably not the most efficient setup. But rather common anyhow.
Is embedded Python code also stored in Globals?
What is the recommended solution for a similar installation?
