Incomplete Training Data

Building Instinct
1

The overview indicates there are 7200 distinct buildings in the dataset; however, the zipped folder I downloaded contains only 2039 buildings. Is there a link to download the rest of the data?

Hi @oluwadaminiolaa and welcome to the ThinkOnward challenges community :wave:

Can you verify the size of the building-instinct-train-data.zip file? It should be 598 MB for the training data and the building-instinct-train-label.zip file with the labels should be 55 KB. You might try re-downloading the training file as it sounds like you only got a portion of the data.

The zip file is actually 570 MB, I have encountered the same thing. Its 2039 rather than 7200.

for me the zip files are 598 mb and 55kb but its stilll incomplete. around 2k buildings. comparing to test zip file we should have around 1.5 gb of train data for 7200 buildings

Hi @bamtungom and welcome to the ThinkOnward Challenges community :wave:

If you are running into issues unzipping the dataset, you might try to unzip the file from the terminal. After you cd to the directory where the zip file is located run

unzip building-instinct-train-data.zip -d /path/to/your/new/directory

Where you change the /path/to/your/new/directory to the path you want to save the training data.This will unpack the data from the zip file it should unpack. Let us know if it does not work and we can keep troubleshooting.
