Array as output data

[warddeboeck]

Hi there,

I'm trying to get out the output data of the Runway Model "Keras-OCR" running locally. It seems link with Runway is set up correctly as I see the output at http://localhost:8000/data.
However I can't seem to reach it in Openframeworks.
offApp.h:

ofxRunway runway;
string runwayResult;

ofApp.cpp:
runway.get("bboxes", runwayResult);

Error:

Input and output specification Runway model:

runway.getOutputTypes() gives:

[
    {
        "description": null,
        "itemType": {
            "description": null,
            "name": "image_bounding_box_array_item",
            "type": "image_bounding_box"
        },
        "minLength": 0,
        "name": "bboxes",
        "type": "array"
    },
    {
        "description": null,
        "itemType": {
            "default": "",
            "description": null,
            "minLength": 0,
            "name": "text_array_item",
            "type": "text"
        },
        "minLength": 0,
        "name": "labels",
        "type": "array"
    }
]

How do I get out the array with ofxRunway?

Hi, that's not how it works. ofxRunway will parse those strings into the data type that those represent.
I just added some examples on how to use Keras-OCR.
Let me know if this is ok or if you still need to access the raw data.

Hi Roy, I would indeed like to get the raw data! To check those strings/text on certain words.

Hi @warddeboeck
That is already accessible.

so instead of running runway.get(...); you need to run the following

	ofxRunwayData dataToReceive;
	while (runway.tryReceive(dataToReceive)) {
//		 dataToReceive.data contains the raw JSON data sent by runway. And it is here where you should perform what ever you need with it.
		break;
	}

Aha thanks, I see!

[roymacdonald]

sure, no problem. I will close this issue and add a note about this in the readme.
Just if you are curious, take a look at ofxRunway.cpp and ofxRunwayData.cpp and you'll notice how most get functions are wrapping the chunck of code I just posted.
cheers
