How to make input fixed in a tensorflow zoo model?

I took a Resnet Inception V2 model from TensorFlow Zoo which should be supported and I retrained it on my custom dataset. After retraining, I took the weights from inference folder and tried to use the mvncCompile on them and got the error:

 

Traceback (most recent call last):

 

File "/usr/local/bin/mvNCCompile", line 118, in

 

create_graph(args.network, args.inputnode, args.outputnode, args.outfile, args.nshaves, args.inputsize, args.weights)

 

File "/usr/local/bin/mvNCCompile", line 104, in create_graph

 

net = parse_tensor(args, myriad_config)

 

File "/usr/local/bin/ncsdk/Controllers/TensorFlowParser.py", line 259, in parse_tensor

 

input_data = np.random.uniform(0, 1, shape)

 

File "mtrand.pyx", line 1309, in mtrand.RandomState.uniform

 

File "mtrand.pyx", line 242, in mtrand.cont2_array_sc

 

TypeError: 'NoneType' object cannot be interpreted as an integer

 

The command I used: mvNCCompile -s 12 frozen_inference_graph.pb -in=image_tensor -on=raw_detection_scores

 

Now I realize this is because movidius doesn't support variable sized inputs but can anyone please tell me where do I change the code to make the input fixed size?

 

This is the model code: https://github.com/tensorflow/models/blob/master/research/object_detection/models/faster_rcnn_inception_v2_feature_extractor.py

 

I'm just a beginner so any help will be appreciated.

 

Thanks

Hi @ali18997

 

Since you're using Tensorflow, you'll have to change your code to declare a specific size for the input placeholder instead of using a variable size (variable sized inputs are set as "none"). Here is an example of a fixed input size:

 

input_image = tf.placeholder("float", [1, image_size, image_size, 3], name="input"). (if this was set to accept variable input sizes, type "None" would be passed).

 

I hope this is helpful!

 

Best Regards,
