MMSegmentation, a part of OpenMMLab, is an open-source semantic segmentation toolbox based on PyTorch.
arcgis.learn provides the
MMSegmentation class which acts as a bridge to train and use the models in OpenMMLab's MMSegmentation toolbox in
MMSegmentation class of
arcgis.learn allows you to train these models using the familiar arcgis.learn API for data preparation, model definition and training. The trained models can then be used in ArcGIS Pro, Enterprise and Online.
Follow the steps here to install deep learning dependencies in ArcGIS Pro or Anaconda environment respectively.
ArcGIS Pro 2.8 users additionally need to install CUDA toolkit version 11, mmcv-full and mmsegmentation libraries. Follow these steps to do so:
- Download and install the latest CUDA toolkit version from here.
- Add the installed CUDA toolkit's bin folder path (typically, C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.0\bin) to the (user or system) Path Environment Variables.
- Run the following command in a cloned environment:
conda install -c esri mmcv-full mmsegmentation
With the basic setup done, we are now ready to define a model supported in MMSegmentation.
arcgis.learn allows us to use any of the supported models from OpenMMLab's MMSegmentation toolkit through a single line of code. For example:
model = arcgis.learn.MMSegmentation(data, model='resnest')
The parameters required to be passed are:
datais the data object prepared using
modelis name of one of the models from the list of supported models.
The following MMSegmentation models are supported through
['ann', 'apcnet', 'ccnet', 'cgnet', 'deeplabv3', 'deeplabv3plus', 'dmnet', 'dnlnet', 'emanet', 'fastscnn', 'fcn', 'gcnet', 'hrnet', 'mobilenet_v2', 'nonlocal_net', 'ocrnet', 'psanet', 'pspnet', 'resnest', 'sem_fpn', 'unet', 'upernet']
Trained MMSegmentation models can be used for inferencing using the Classify Pixels Using Deep Learning tool in ArcGIS Pro.
