Unable to download silcam_database.zip from exampledata.py

[arsalanmstn]

The exampledata.get_classifier_database_from_pysilcam_blob(download_directory='./') does not download the silcam_dataset.zip. When running the function, it only returns download_directory.

sounds like a bug here.

If i do:

exampledata.get_classifier_database_from_pysilcam_blob('silcam_classification_database')

then I get a folder structure with tiff files in each of the classes in a directory called 'silcam_classification_database'

The problem with this function is that it checks for existing folder (download_directory), and if it exists, it does nothing, just returning the name of the folder. Combined with the default option of download_directory='.', this creates the observed behavior.

Work-around: always specify a non-existing folder
Fix: Remove default value for "download_directory", or change it to something else, for instance a randomly generated name.
