Rossmann Data

Can we use differential learning rates for training neural networks on structured data like rossmann.

Hi Umar

the Rossman data is not to be found at files.fast.ai, do you know where it is. Thanks for your assistance

It is here http://files.fast.ai/part2/lesson14/rossmann.tgz

Yes, you can. StructuredModel has 3 groups of layers (embeddings, linear + batch norm and output).

thanks

In lesson 6 rossmann, i"m not able to run the “roassman_data_clean” in google colab. I face this error(below) when i tried to run this code:

PATH=Config().data_path()/Path(‘rossmann/’)
! wget -P {PATH} http://files.fast.ai/part2/lesson14/rossmann.tgz
table_names = [‘train’, ‘store’, ‘store_states’, ‘state_names’, ‘googletrend’, ‘weather’, ‘test’]
tables = [pd.read_csv(PATH/f’{fname}.csv’, low_memory=False) for fname in table_names]
train, store, store_states, state_names, googletrend, weather, test = tables
len(train),len(test)

the error:

Hi.
You didn’t unzip the rossmann.tgz file, so there is no file named train.csv

You need to use the command below after ! wget .... to unzip
!tar -xzf rossmann.tgz -C ./data/rossmann/
