How to get weights of the NN

[Efe Bakioglu]

Hi,

I'd like to download the weights and biases of the layers of my trained NN, just to use in an offline application of mine, is it possible? I couldn't find any way to even see them.

Regards, Efe

Sorry, I missed to post.

Hi,

Do you use Neural Network Console Cloud?

If so, you can download nnp/nnb/onnx file from each job on training tab.

.nnp (just zip archive) contains network graph and parameters written by h5 or protobuf format.

If you use Neural Network Console Windows, the files are available on project directly.

Thank you very much.

Yes I am using Neural Network Console Cloud. I will have a try.

Found it, wanted to share the basic python code I used, both for nnp and onnx files.

Thank you again.

import numpy

from nnabla.utils.nnp_graph import NnpLoader

nnp = NnpLoader('result_train_best.nnp')
net = nnp.get_network("MainRuntime")
c = net.variables["Convolution_2/conv/W"]
print(c.d)

import onnx, onnxruntime
onnx_model = onnx.load( 'result.onnx' )
for n in onnx_model.graph.initializer:

    print(onnx.numpy_helper.to_array(n))
