The fast segmentation convolutional neural network (Fast-SCNN), an above real-time semantic segmentation model on high resolution image data (1024x2048px) suited to efficient computation on embedded devices with low memory.
The 'learning to downsample' module which computes low-level features for multiple resolution branches simultaneously.
The network combines spatial detail at high resolution with deep features extracted at lower resolution.

Go to visit COCO official website, then select the COCO dataset you want to download.
Take coco2017 dataset as an example, specify /path/to/coco2017
to your COCO path in later training process, the unzipped dataset path structure sholud look like:
