Hi Ben, I just found this awesome example in the RadioML repo https://github.com/radioML/examples/blob/master/modulation_recognition/ RML2016.10a_VTCNN2_example.ipynb
Which I'd not seen before, I'll update my CNN model generation to make sure it creates the model in the same way as that. (Sorry if you get this mail twice Ben, I forgot to hit reply to all first time) Cheers Chris On Fri, Jan 6, 2017 at 12:21 AM, Christopher Richardson < [email protected]> wrote: > Hi Ben > > I think it looks like you haven't generated the model, if I'm > understanding correctly, for the GRC file. > > At the moment the code to generate the models is at: > https://github.com/chrisruk/models > > Tomorrow I'll check that the model generation works with the latest > version of TensorFlow for you. > > If anyone has experience with Keras, I'd love to have someone have a look > over of the correctness of the models, > as I seem to have lower accuracy with the Keras models, than when they > where implemented with TFLearn if I recall > correctly, which is very odd. > > Cheers > Chris > > > On Thu, Jan 5, 2017 at 9:45 PM, Ben Hilburn <[email protected]> wrote: > >> Hey all - >> >> I'm trying to get some of the tensorflow gr-inspector examples up and >> running, and running into a few hiccups (note that the non-tensorflow >> flowgraps work fine).
