VIsualize network by using python

[Pan.H.BestSonny]

I want to visualize my network using python.But I do not know how to start it.I notice there is a draw.py in Python wrapper.

Anyone to give me a example.Thank you!

Everything you can find here: http://nbviewer.ipython.org/github/BVLC/caffe/blob/master/examples/filter_visualization.ipynb

If by visualizing the network, you mean drawing the structure of the network, use:

$ caffe/python/draw_net.py <netprototxt_filename> <out_img_filename>

I'm trying to draw my net in Caffe. The net is defined in `expt/expt.prototxt` and the desired image path is `expt/net.png`. When I run the command `./python/draw_net.py expt/expt.prototxt expt/net.png`, I get the following error:

    Couldn't import dot_parser, loading of dot files will not be possible.
    Drawing net to expt/net.png
    Traceback (most recent call last):
      File "./python/draw_net.py", line 44, in <module>
        main()
      File "./python/draw_net.py", line 40, in main
        caffe.draw.draw_net_to_file(net, args.output_image_file, args.rankdir)
      File "/home/pras/caffe/python/caffe/draw.py", line 165, in draw_net_to_file
        fid.write(draw_net(caffe_net, rankdir, ext))

        'GraphViz\'s executables not found' )
    pydot.InvocationException: GraphViz's executables not found

I'm running Caffe on Ubuntu 14.04 in CPU mode using the Anaconda Python interface. Any ideas why this error might be occuring and how to go about correcting it?

Hi all,

I am also trying to draw net using draw_net.py. But it fails to draw net from imagenet prototext too( given in example folder).

Can anyone please help on it?
 
I did :

python draw_net.py <protext> <outfile>

[Tharu]

Hi,

I am still not able to fix this problem. Has anyone fixed it?  Could someone help me please?>

Hi everyone!

I had the same problem when I installed pydot via pip

I removed it and installed it from the ubuntu repository "sudo apt-get install python-pydot"

Hope this helps!

It looks like the examples have been relocated (?) -- anyone know where they can be found now?

[Amir Abdi]

I am also looking to find the sample code for visualization. Can't find it.

[Eder Ruiz Maria]

You need install GraphViz

If you are using ubuntu: sudo apt-get install graphviz

[Felipe Cicero]

I Found this version, the exemples directory of caffe has one copy as well...

[Hossein Hasanpour]

the draw.py inside python directory is only used to give you an image file of your architecture so that you can see how your model is structures. 

if order to visualize intermediate layers, you would like to have a look at 00-classification.ipynb located at Caffe_Root/Examples.

i get an error like this

google.protobuf.text_format.ParseError: 1:1 : Message type "caffe.NetParameter" has no field named "net".

when I try drawing a net like this:

$ python python/draw_net.py models/bvlc_reference_caffenet/solver.prototxt out.bmp

Does anyone know why this would be happening? 

[Kaushik Pavani]

Try passing train_val file instead of solver.prototxt

I believe it has become this:

Hi guys, please help! who knows how to improve a quality of the images produced by draw_net.py? They are 96 dpi, I need 300 dpi. Please advice! Cheers,Vlad

Oh, I just figured out how to solve it, just play with a picture in Adobe Photoshop, that's it! Cheers, Vlad
