fail to install mxnet in ios (El Capitan) and run python (2.7) examples

I have tried to run install Mxnet deeplearning framework but I failed because of the following error when I tried to run the python example, and I could not find the best treatment in the web.

MacBook-Pro-4:mxnet chinhiroshi$ python example/image-classification/train_mnist.py

The save_model_prefix was introduced just 15 days ago. You most likely installed mxnet before that, and therefore have a version that doesn't support it.

You can either reinstall latest mxnet from source, or fix the problem in the example itself. For that open train_model.py (see the full path in your backtrace), and change the following four lines:

save_model_prefix = args.save_model_prefix
if save_model_prefix is None:
    save_model_prefix = model_prefix
checkpoint = None if save_model_prefix is None else mx.callback.do_checkpoint(save_model_prefix)

with:

checkpoint = None if model_prefix is None else mx.callback.do_checkpoint(model_prefix)
