Please use the FAM model at the moment, I'm just tweaking the CNN model, as I need to implement 64 sample shifts.
ChrisHi 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)CheersOn Fri, Jan 6, 2017 at 12:21 AM, Christopher Richardson <address@hidden> wrote:ChrisHi BenI 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 recallcorrectly, which is very odd.CheersOn Thu, Jan 5, 2017 at 9:45 PM, Ben Hilburn <address@hidden> 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). I'm using the non-GPU version of tensorflow (`$ sudo pip install tensorflow`) as I don't have an nVidia GPU.With the `amc_cnn` example, I was first getting the following error:Not really being sure what that was, I created the `/tmp/cnn/00000001/` directory, touched the `export.meta` file, and moved on (this may have been my first mistake).RuntimeError: Expected meta graph file missing /tmp/cnn/00000001/export.metaAnyway, it gets a bit further, but dies with this:Executing: /usr/bin/python2 -u /home/bhilburn/code/gnuradio/gr-inspector.git/examples/top_b lock.py Traceback (most recent call last):File "/home/bhilburn/code/gnuradio/gr-inspector.git/examples/top_ block.py", line 139, in <module> main()File "/home/bhilburn/code/gnuradio/gr-inspector.git/examples/top_ block.py", line 127, in main tb = top_block_cls()File "/home/bhilburn/code/gnuradio/gr-inspector.git/examples/top_ block.py", line 75, in __init__ self.inspector_tfmodel_vcf_0 = inspector.tfmodel_vcf("complex64",128,'/tmp/cnn/00000001',() ,0) File "/home/bhilburn/usr/lib64/python2.7/site-packages/inspector/ tfmodel_vcf.py", line 64, in __init__ sess, inp, out,classes = self.load_graph(graphfile)File "/home/bhilburn/usr/lib64/python2.7/site-packages/inspector/ tfmodel_vcf.py", line 88, in load_graph signatures_any[0].Unpack(signatures) File "/usr/lib/python2.7/site-packages/google/protobuf/internal/c ontainers.py", line 204, in __getitem__ return self._values[key]IndexError: list index out of rangeAny ideas / pointers?Cheers,Ben
