2) Download COCO images. I’d recommend downloading a valuation set just to try things out first. 3) Download the corresponding annotations for that image set that you’ve downloaded. *Both 2) and 3) can be downloaded from the COCO official site. Unzip the cocoapi to a folder of your choice.
What’s the Unzipped folder for the cocoapi Master?
For me, the unzipped folder is called cocoapi-master. But depending on the version you downloaded, it could be named something else. Next, I had my own python scripts nested in the PythonAPI folder. These scripts are copied and then edited from the python demos which they’ve provided on their official Github page.
