Deep Learning prepare_data

[LaurynasGedminas2]

Hello,

I am following the example here for pixel classification:

Pixel-based Classification Workflow with | ArcGIS for Developers 

In my case I am exporting data and labels from ArcPro, when i run:

data = prepare_data(data_path, batch_size=16)

I get error:

TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'''

What is the parameter settings needed in ArcPro to export data for this example?

API version: 1.7.0

ArcGIS Pro 2.4

Thank you,

If i export data as 'labelled tiles' i get error:

lib\site-packages\arcgis\learn\_data.py in prepare_data(path, class_mapping, chip_size, val_split_pct, batch_size, transforms, collate_fn, seed, dataset_type, resize_to, **kwargs)    357     358     if dataset_type is None and not has_esri_files:--> 359         raise Exception("Could not infer dataset type.")    360     361     if dataset_type != "Imagenet" and has_esri_files:Exception: Could not infer dataset type.

Try specifying the dataset_type. So for Classification tiles, add dataset_type='Classified_Tiles' to call the prepare_data function.

when i try to export  'Classified Tiles' thru export tool it gives error: ERROR 002091  Parameters are inconsistent.

Can you post a screenshot of parameters you have supplied to the tool.

this gives the ERROR 002091  Parameters are inconsistent. 

it's 3 band raster, TIFF or PNG still the same, sites were produced by the Training Sample Manager:

Can you check if there is any missing values in the ClassValue column .

I just went through this problem. Documentation says that exporting "classified_tiles" requires a classified raster (thematic) instead of feature class. So I had to do polygon to raster, then 'set raster properties'. Once I did that It let me export. Not sure if this is the correct way. 

EDIT: looking at the 'extract building foot prints' here, my workflow with ultimately not work. I'm trying to prepare the data now for training and I'm getting errors.

You can follow the steps documented here https://developers.arcgis.com/python/sample-notebooks/extracting-building-footprints-from-drone-data...
