Coremltools issue

[paultas]

I created .py file according to Apple instruction Apple Instuction and Documentation

import coremltools

# Convert a Caffe model to a classifier in Core ML
coreml_model = coremltools.converters.caffe.convert(
    ('nin_imagenet_conv.caffemodel', 'train_val.prototxt'), predicted_feature_name='class_labels.txt'
)

# Now save the model
coreml_model.save('nin_imagenet_conv.mlmodel')

Then in Terminal I run python convert.py

But then I get a error:

This is not at all related to Neural Style so I doubt you will get much help here. I would suggest looking for help in nin imagenet related forums.

I don't know, because the link is on the main page, so hope somebody faced this issue 😊

Just because one project might use a model from another project does not mean that is the right place to look for support. I'm trying to help you and steer you in the right direction.

Thank you, I wrote on that forum
