3 years ago I checked host.robots.ox.ac.uk and that site is not responding. Has been down for several days. I found an alternative mirror for the three data sets, and that worked. http://pjreddie.com/media/files/VOCtrainval_11-May-2012.tar and the other two tar files as well. exactly the same names, and same size. I also found a mirror at Baidu but the file names were different (encapsulated in a zip file I believe). Anyway, it would be great if you could update the notebooks with working repositories, even better if they were within AWS.
Hi. I am trying to walk through the 10-minute tutorial on Optimizing and Scaling Machine Learning Training. When I try to run my copy of the managed-spot_training_object_detection.ipynd notebook, following the tutorial steps exactly, I get a fatal error at Download and Prepare Data. --2020-10-12 23:50:32-- http://host.robots.ox.ac.uk/pascal/VOC/voc2012/VOCtrainval_11-May-2012.tar Resolving host.robots.ox.ac.uk (host.robots.ox.ac.uk)... 129.67.94.152 Connecting to host.robots.ox.ac.uk (host.robots.ox.ac.uk)|129.67.94.152|:80... failed: No route to host. --2020-10-12 23:50:35-- http://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCtrainval_06-Nov-2007.tar Resolving host.robots.ox.ac.uk (host.robots.ox.ac.uk)... 129.67.94.152 Connecting to host.robots.ox.ac.uk (host.robots.ox.ac.uk)|129.67.94.152|:80... failed: No route to host. --2020-10-12 23:50:38-- http://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCtest_06-Nov-2007.tar Resolving host.robots.ox.ac.uk (host.robots.ox.ac.uk)... 129.67.94.152 Connecting to host.robots.ox.ac.uk (host.robots.ox.ac.uk)|129.67.94.152|:80... failed: No route to host. tar: /tmp/VOCtrainval_11-May-2012.tar: Cannot open: No such file or directory tar: Error is not recoverable: exiting now tar: /tmp/VOCtrainval_06-Nov-2007.tar: Cannot open: No such file or directory tar: Error is not recoverable: exiting now tar: /tmp/VOCtest_06-Nov-2007.tar: Cannot open: No such file or directory tar: Error is not recoverable: exiting now Traceback (most recent call last): File "tools/prepare_dataset.py", line 95, in

I will go look at the data repository website to see if there is an update to the files, but in the meantime please check the notebook and correct the data download so us users can make progress.
Thank yoiu.
