ValueError: Cannot create group in read only mode

[angyee]

i am running

sudo python3 keras_to_tensorflow.py --input_model=/home/deepedge/mask_rcnn-master/mask_rcnn_damage_0010.h5 --output_model=/home/deepedge/mask_rcnn-master/dent.pb

and getting error

Using TensorFlow backend.
E0619 15:22:44.379571 140399717234496 keras_to_tensorflow.py:95] Input file specified only holds the weights, and not the model definition. Save the model using model.save(filename.h5) which will contain the network architecture as well as its weights. If the model is saved using the model.save_weights(filename) function, either input_model_json or input_model_yaml flags should be set to to import the network architecture prior to loading the weights.
