Tensorflow converting keras model for tensorflowjs

Question

Using standard code import tensorflow as tf import tensorflowjs as tfjs

 tfjs_target_dir = 'c:/files'
 model = tf.keras.applications.InceptionV3(
     include_top=True,
     weights='imagenet',
     input_tensor=None,
     input_shape=None,
     pooling=None,
     classes=1000
 )
 tfjs.converters.save_keras_model(model, tfjs_target_dir)

I get the following error

File "C:\\Program Files\\python36\\lib\\site-packages\\tensorflow\\python\\client\\session.py", line 1321, in _do_run run_metadata)

File "C:\\Program Files\\python36\\lib\\site-packages\\tensorflow\\python\\client\\session.py", line 1340, in _do_call raise type(e)(node_def, op, message)

Answer 1

Have you tried to provide an input shape?

eg

if K.image_data_format() == 'channels_first':
    input_shape = (3, img_height, img_width)
else:
    input_shape = (img_height, img_width, 3)

with img_height/width is the size of the pictures you want to predict
