Keras example - AttributeError: module 'utils' has no attribute 'batch_slice' #15

Trying to run the Keras example. When choosing the provided mask_rcnn.emd file in the geoprocessing tool in ArcGIS Pro the below error is shown:

Unable to initialize python raster function with scalar arguments.

I think whats happening is that model.py is trying to import utils.py but is finding a different utils module somewhere else in the system.

The only way I could get around this was to rename utils.py to mrcnn_utils.py and then modify model.py.

From:

import utils

To:

import mrcnn_utils

And then search and replace all the utils.Function statements to be _mrcnnutils.Function. Be careful when doing this as there are are references to utils such as distutils and keras.utils which should not be changed.

When doing all these changes I could successfully run the keras example.

Hi @tim-mcg thanks for your post. yes, if you already have a 'utils.py' module in your PYTHONPATH that would cause a name conflict hence this python module would first load the utils in your PYTHONPATH. We will try to resolve this by using relative import.
