A string, one of "channels_last" (default) or
"channels_first". The ordering of the dimensions in the inputs.
"channels_last" corresponds to inputs with shape
(batch, ..., channels) while "channels_first" corresponds to
inputs with shape (batch, channels, ...).
When unspecified, uses image_data_format value found in your Keras
config file at ~/.keras/keras.json (if exists). Defaults to
"channels_last".
