arcgis.learn.prepare_data() error calling dataset_type='RCNN_MASKS'

Anonymous User

Hi,

I'm getting an error when calling the prepare_data function in arcgis.learn. The error seems to originate from the data.py file inside the arcgis.learn site-package, inside the dataset_type == 'RCNN_Masks' statement. The error says that the variable 'right' is not yet assigned (which is true because it seems it is only defined inside another dataset_type statement).

API version: 1.7.0

ArcGIS Pro 2.5

Here's the error message. It indeed says 'could not infer dataset type', however the folder is correct AND the emd files is inside that folder (this accounts for both classified tiles and rcnn masks datasets).

Message for using Classified Tiles dataset:

Folder for the classified tiles, including the emd file as well:

Dependencies in my geoai env:

Exactly the same happens when I use a RCNN mask dataset.

Can you put a screenshot of the error which you get when you do not specify the dataset_type, we get the error message 'Could not infer dataset type.' when we supply a wrong folder or the emd file is missing.

That doesn't work, I'll get the same error as what is asked here: https://community.esri.com/message/894425-re-deep-learning-preparedata?commentID=894425&et=watches.email.thread#comment-894425. The dataset_type parameter actually helped me further already then trying to do without.

The problem seems to be in the _data.py script, I see a couple of mistakes there. And it also appears to be there in multiple arcgis api versions..

The tutorial to follow you proposed in the other comment about extracting building footprints, I actually tried to follow, but since there is nothing really specified about error handling, it doesn't help me any further. The same errors appear, no matter if I use a Classification tiles dataset (with or without specifying the dataset_type Classification_Tiles as well), or if I use the RCNN_Masks.

Do you know which version of the arcgis api was used to make the tutorial? Cause it probably has worked in that specific version..

The prepare_data function will automatically detect the 'dataset_type', try to remove the 'dataset_type' parameter from the function call.
