Hi,I have been using nodered for a short time and i have a question about python function. When i insert a python function, in the debug this sentence appears: " s = s.decode(detect_encoding(s), 'surrogatepass') File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.7_3.7.1776.0_x64__…

Which node are you using to put your python code in? The standard function node is for javaScript but there are a couple python nodes out there

The error you're dealing with is a somewhat infamous Python error when it comes to dealing with Unicode. I say somewhat infamous as most of the time it's caused by a user error. Start reading here: https://docs.python.org/3.7/howto/unicode.html As the error path shows you're running Python 3.7 on W…

I'm using either Python Function node and Python 3 Function

I'm using either Python function and Python 3 function. I tried this with a simple function node: -Inject node with a payload numer that is 4 -Function: msg.payload='hello' + msg.payload return msg; -Debug Then i deploy and it works. I obtain 'hello4'. Since i have to use an algorithm writte…

I don't have an example, because usually if I need to execute code in Python, I run it through the exec node or set it up to communicate with Node-RED over MQTT. I am however quite experienced with Python as it is/was my primary programming language of the last decade so I've no problem debugging it…

I'm using these: npm install node-red-contrib-python-function npm install node-red-contrib-python3-function Now i've installed also npm install node-red-contrib-pythonshell. I put my algorithm (that is a script) in the pythonsell and it works. My algorithm takes a vector in input and throught a …

[image] fabio: Now i want to give in input a vector ( so i want to remove my input vector from the algorithm and i want to give it from external), how can i do with nodered? Did you read the node's description: node-red-contrib-pythonshell (node) - Node-RED

[image] fabio: if you haven't understood Share your flow correctly and you will get best possible help Also list what external nodes you have installed

[plottare] My flow is this.There is a "pythonshell in" node that is an algorithm and it produces those arrays media1,sigma1, etc.. in the debug. I also connected the output of the pythonshell to a chart that appears in a dashboard because i want to plot those arrays. How can i do this operation?

The output is one large string, with as you can see those arrow symbols in between, also known as linebreaks. Your first step would be formatting the output to a format you can easily use in Node-RED, preferably on the python side. For example, a dictionary that you print as json.dumps(...), then pa…

Since you opened a new thread about the chart question, please mark this one solved so people won't spend any more time on it.
