Can't get the dataset "Lung cancer (Ontario)".

[Sier-xyt]

it has an error when running the example.py

urllib2.HTTPError: HTTP Error 404: Dataset 'lung-cancer-ontario' not found on mldata.org.

Yes, I also encountered a similar error. You can try using another dataset for example "heart".

Since the lung-cancer-ontario are not found, I use colon-cancer instead. But I found the following error. I thought it might cause by size of data-set but I don't know how to fix it. Any suggestions please?
Traceback (most recent call last):

Same issue here. Would like to have any help, or workaround to get the data. Thanks!

Follow-up question: HDF5 format is available at http://mldata.org/repository/data/viewslug/lung-cancer-ontario/ though. Is there any way to convert it to the expected .mat format?
