Step 0, cell 2

Download sample training data to notebook working directory

import wget
training_data_url = 'https://dataplatform.cloud.ibm.com/data/exchange-api/v1/entries/aa07a773f71cf1172a349f33e2028e4e/data?accessKey=e98b7315f84e5448aa94c633ca66ea83'
filename = wget.download( training_data_url )
print( filename )

The URL for downloading the sample training data does not work
{"messageKey":"unspecified","message":"Internal Error"}

Can you please tell me where this file can be dowloaded so I can continue the tuto.

Thanks in advance for your help.
