Error while trying to get outputs of googlenet

[iaroslav-ai]

I try to get output of googlenet with some randomly generated inputs using a modified version of googlenet_neon.py. I get warning and error messages below. Did I made some mistake or is there a bug? The code that I use is below error messages.

The code:

Assume that googlenet model is located at /home/iaroslav/temp/googlenet.p.

The ArrayIterator needs to have the data as a 2D matrix with the dim (N, CHW). So the CHW part needs to be squashed and it needs the shape parameter set to (C, H, W). Try changing line

test = ArrayIterator(np.random.rand(256,224,224,3))

to

test = ArrayIterator(np.random.rand(256, 3_224_224), lshape=(3, 224, 224))

Ah I see I used now test = ArrayIterator(np.random.rand(256, 3*224*224), lshape=(3, 224, 224)) I also added in the end print model.get_outputs(test) It seems that now neon does something for some time, but then in the get outputs function it gives the error

Traceback (most recent call last):

    print model.get_outputs(test)

    (dim0, dim1) = x.shape
AttributeError: 'list' object has no attribute 'shape'

Did I do something wrong again? :) I have my updated code in here

Thanks for your response! :D

[nervetumer]

Could you pull the most recent model zoo repo and try again, I think the model needed to be updated to use the SingleOutputTree

[iaroslav-ai]

Thanks for your response! I will try to pull the most recent model zoo.

I guess this can be closed due to #3 ?

[nervetumer]

Not sure if this relates to #3. Would be good to make sure that this is working for you.
