Error in train.py

When I ran the train.py file using the options as num_gpus 1 and batch_size 10, it throws the following error :

[ERROR:2017-05-08 12:42:08,943] Exception in QueueRunner: 0-th value returned by pyfunc_0 is double, but expects float

We are really sorry about making mistakes in our code. This error is caused by cnn_feature_extractor.py, which should save pool5 feature as float type but it currently save pool5 features as double type.

I will fix it soon but as a workaround, you can manually do type casting when loading pool5 feature. e.g. In utils/data_utils.py, line 91

np.load(os.path.join(FLAGS.img_data_dir, batch_path[i])).astype(np.float32)

Okay. Thanks!!
