Hello,

To work around the impossibility of calling some useful Python libraries inside Ignition:

I’d like to know if there is a way to, inside Ignition, call a Python file outside of Ignition to run the code with the libraries that I want, and then sending it back to Ignition in maybe a text format. Do anyone know if that would work / be possible?

Thanks in advance!

I did something similar for one project. I’ve built a program for a high-speed camera in C++.  
The sequence was:

- A script inside ignition that executes the C++ program

```auto
def execute():
	import subprocess
	encoding = 'latin1'
	cmds = ['cd C:\\Users\\Tecno\\Desktop\\Cristian\\Camera C++\\Camera_Test\\bin\\Debug', 'Camera_Test.exe']
	p = subprocess.Popen('cmd.exe', stdin=subprocess.PIPE,stdout=subprocess.PIPE, stderr=subprocess.PIPE)
	for cmd in cmds:
		p.stdin.write(cmd + "\n")
	p.stdin.close() 
	temp = p.stdout.read()
	if "FAIL" in temp:
		print "Failed"

```

I had to do it like this ( with two commands ) otherwise it didn’t work 🤔

- The C++ program executes and returns the output on a .txt file
- From Ignition I read the .txt file
