Out of the box issue with dataset extractor

[alfredoandere]

I am following the instructions in the dataset extractor section. I am downloading the dataset from the link provided and placing it inside www/data/src Working with the following environment.

$pip freeze
|numpy==1.19.1
│opencv-python==4.4.0.42
│pytz==2020.1
│tornado==6.0.4

When I run python3 webgazerExtractServer.py the server starts up fine with the following message

[I 200822 01:20:30 webgazerExtractServer:395] Listening on [::]:8000
WebGazer ETRA2018 Dataset Extractor server started; please open http://localhost:8000/webgazerExtractClient.html

THEN when I open that link in chrome (or safari) it gives out the error: (and does not process anything)

[I 200822 01:21:03 web:2250] 200 GET /webgazerExtractClient.html (::1) 6.80ms

        f = os.path.split( webMFile[0] )[1]
    IndexError: list index out of range

Would really appreciate any help with this. Thank you in advance!

It looks like you video files aren't in the right place. P0, P1, and all the other folders will need to be extracted out in the same folder.
