For those having issues, inside your py.GIL block add this
dynamic sys = Py.Import("sys");
sys.path.append ("your folder spec "); /| the folder where your python scripts are.

[stefanosantimone]

To change the path for the scripts, before importing the script, just add:

dynamic sys = Py.Import("sys");


Great presentation. Thank you!

Thanks Nick for the video.
Anyone struggling with no module found error for the .py file? First add the .py file in the current csproject path. Then add the line of code System.Environment.SetEnvironmentVariable("PYTHONPATH", "my_project.py") in your .cs file.
Even though I added this path manually in PYTHONPATH system variable it was not working for me and I had to include path of the .py path using the above code to make it work.

[adnartmadmartm]

This was well done. Covered a couple of basic cases and showcased the use quite clearly.

Great Video Nick. Didn't know about this library! Thanks for sharing this one with us!! 👏

Question: if i want to use python script for data processing and then create the domain objects in c# what would be the best strategy to do it?

[mikemuller]

I can't believe it ... I finally got this to work lol, not Nick's fault, my ignorance ... which has recently decreased every so slightly haha

[ricardopucca]

I had problems with 'No module named' on debug! And I solve this installing pywin32:
pip install pywin32

I have 312 Python and this code is not working. .Net framework 4.7.2

Thank you for the video, it would be great to see IronPython too, hopefully you can do a video about it in the near future. :)

[anjureddy]

Hello, hope you are doing well, you have explained clearly how to use or embed python in c# it saved me a lot of time.

If possible, can you make a video on how to use .pyd( python dynamic library) file in c# using pythonnet?

[rjotzbd]

Great tutorial.
I tried this but when I run the code I get error. this occurs on the Python.Initialize line. Do I need to add a path to system variable? Using visual studio 2022 c# in a win forms application. any help is appreciated. thanks

How to set the python virtual environment before calling the script from C#?

[MrTheOctavius]

I've followed your exact same steps but get the exception 'No module named 'mypythonscript' ". Am I missing something?

[SilverSurfer]

Thank you for this! I got your example to work, but when I tried to roll my own python script, which imports numpy, I get this delightful error message: No module named 'numpy'

Any suggestions to get numpy and other nonstandard libraries recognized?

[baole]

I have some problems with loading the dll file, can you help me? I am using the same version as you.

[satinderjeetsingh]

i need to run the pyhton script as test cases how i can do that please help its urgent, like right now I have create class in new test project and trying to run that script but lot of issue like dll not found and lot other, I am not sure if it should be the same directory or what just waiting for your reply hope something helpful

[priyanshuaggarwal]

This code is not running for py version 3.12 and .net 8.0 with Python.NET version 3.0.3, as it is showing a python runtime exception because the py script is not being imported

[bandasanthosh]

So without installing Python we cannot run python scripts? if that is the case then this can be run from cmd as well using C#. Is my assumption correct?

[mohdwasif]

Hi Nick, it's a nice video.
I am trying to replicate the same behavior as you taught in the video but I am getting an exception : No module named 'Hello'. Actually I have created a python file 'Hello.py' in the same directory with exact same code as you have shown in the video but I am getting this strange exception:(
