I have replicated the code on this training example
And are interested in the F1 and mIOU metrics. The example shows F1 metrics which for me came out similar (but not exactly) to the example. They are all in the around 90 mark, all good. My question is when, I run the mIOU score, the scores are 30 or less. Which would seem really low compared to F1. Why are the mIOU scores so low?
I am running arcgis 1.8.2 and fastai 1.0.60
