How can I use this implementation to train on my own data?
Hi, in paper (Figure4, ReductionCell) there are only 3 layer for Concate input , as you code (line 300 in nasnet.py) ,it should be
return Concatenate(.....)([add_2, add_3 add_4])
add_1 is not in Concate input!!!! please check it.
I tried to finetune NASNet like a Keras K.application
model however, there is no weights
kwarg. For example, for Xception it defaults to loading the imagenet
pretrained weights.
I tried to use some of the functions provided in the package as follows,
import nasnet
origin = 'https://storage.googleapis.com/download.tensorflow.org/models/nasnet-a_large_04_10_2017.tar.gz'
fname='nasnet_large'
md5_hash='5286bdbb29bab27c4d3431c70f8becf9'
cache_dir = os.path.expanduser(os.path.join('~', '.keras', 'models'))
model = nasnet.NASNetA(include_top=False, input_shape=(img_height, img_width, 3))
nasnet.load_pretrained_weights(model, fname, origin, md5_hash,
skip_first_dense=True, cache_dir=cache_dir)
However, this throws the error,
ValueError: Layer weight shape (1, 1, 96, 8) not compatible with provided weight shape (1, 1, 96, 42)
What is going wrong here? Better still, it would be great to get a weights kwarg built in to make it fully follow the Keras API. Many thanks.

Hi, thank you for your sharing. And I am confused about penultimate_filters !!! Is it only used in Line 354(nasnet.py) ??
