+git clone https://github.com/perseusdg/monodepth2
+cd monodepth2
+mkdir models # Download the official weights and put depth.pth and encorder.pth inside this new folder
+conda env create --file monodepth.yaml
+conda activate monodepth2
+python exporter.py # you will find the weights inside the tkDNN_bin folder
