ArcGIS Pro includes built in tools that allow end-to-end deep learning, all within the Arc interface – from training sample labelling, through model training and final image classification / object detection. This removes the need for coding and installing the correct versions of the required libraries for machine / deep learning in Python.
However, training deep learning models is an extremely processing-heavy task that requires the use of your GPU to even be slightly feasible in terms of processing time.
Although, Deep Learning in ArcGIS Pro is not possible straight out of the box. This post will walk through how to get everything set up, based on my experience with ArcGIS Pro 2.8/2.9 and the graphics cards listed below. Processes / software versions are sure to change in the future, so I will try and keep the instructions as general as possible.
