error while running python try_convnet_cc_multirotflip_3x69r45_maxout2048_extradense.py

[great-thoughts]

Hi,
I was trying to run python try_convnet_cc_multirotflip_3x69r45_maxout2048_extradense.py however, I am getting some errors. I am running this on an amazon instant with GPU 4Gb.

ubuntu@ip-172-31-19-167:~/kaggle-galaxies$ python try_convnet_cc_multirotflip_3x69r45_maxout2048_extradense.py

No idea what's going on here. Maybe you're using the latest numpy version or so? This code is about 1.5 years old and has not been updated (nor will it be), so you might have to use older versions of some packages to get it to run out of the box. I recommend looking into virtualenv for that purpose.
