Hello!

I'm working in Ubuntu and using Python API

I'm trying to run my YOLO3 Mobilenet model in Neural Compute Stick.

When I run: sudo python3 mo.py --input_model /home/Desktop/keras_to_tensorflow-master/logs/tf_model.pb --input_shape [1,416,416,3],[1,13,13,3,10],[1,26,26,3,10],[1,52,52,3,10] --input input_1,input_2,input_3,input_4 --output yolo_loss/Select, I get this error

Hi Val,

I see this is a converted model from Keras to Tensorflow - did you convert yourself? Can you please attach your model so I can take a look at it?

Best Regards,

Sahira

Hello, Sahira.

Thank you for your comment. It is a private model , would you please PM me and I can privately send you the model.

I converted model from Keras to Tensorflow using keras_to_tensorflow.py https://github.com/amir-abdi/keras_to_tensorflow

When I run:

sudo python3 mo_tf.py --input_model /home/Desktop/keras_to_tensorflow-master/logs/tf_model.pb --input_shape [1,416,416,3] --input input_1 --output conv2d_7/BiasAdd,conv2d_15/BiasAdd,conv2d_23/BiasAdd

i get this error:
