get_UCR_data function fails due to changed download link #785

Closed trungle15 closed 1 year ago

trungle15 commented 1 year ago

I have been working with the tsai library and ran into an issue when attempting to use the get_UCR_data function. It appears that the UCR time series data repository has changed its download link, causing the function to fail and return the message: 'It has not been possible to download the required files'.

Looking at the source code for get_UCR_data, the current source website is defined as src_website = 'http://www.timeseriesclassification.com/Downloads'. However, it seems the correct website should be: http://www.timeseriesclassification.com/ClassificationDownloads.

Here is the current code in the external.py script under data directory:

src_website = 'http://www.timeseriesclassification.com/Downloads'
decompress_from_url(f'{src_website}/{dsid}.zip', target_dir=full_tgt_dir, verbose=verbose)

Proposed update:

src_website = 'http://www.timeseriesclassification.com/ClassificationDownloads'
decompress_from_url(f'{src_website}/{dsid}.zip', target_dir=full_tgt_dir, verbose=verbose)

Hi @trungle15, Thank you so much for raising this issue and adding the solution! The link has indeed changed so it needs to be updated. I've just fixed it! And will be part of a new release that will come out soon.
