training the ImageNet model

[gclouding]

I have successfully run the mxnet on Mnist dataset using the python scripts in the example. However, when running the ImageNet example, error occured. First I run the data.py (this is normal without error) and then alexnet.py , error prompted announcing that Segmentation fault (core dumped).

In the data.py, what is the data structure of " path_imgrec= "data/ilsvrc12/train.rec" ", and how to generate the data ? What should be done before running alexnet.py on ImageNet Dataset ?

Thanks for trying new tools. We don't finish all things in MXNet yet. We will make a detailed doc about how to train ImageNet. data.py is not for generating data but declaration of data iterator. The segfault is because DataIter didn't find the image rec file in path, We will make a more clear error info.

We hope to finish all docs and code in today or tomorrow.
