Can't create graph visualizations with resnet

[lim0606]

Hi,

I tried to draw ResNet (https://github.com/facebook/fb.resnet.torch/blob/master/models/resnet.lua)

However, I got following error;

/home/jaehyun/github/torch/install/bin/lua: ...hyun/github/torch/install/share/lua/5.2/nn/Container.lua:67:

Is there anyone who can help me to find this problem?

Thanks

Best regards,

I think you need to require cunn as well as nn.

[fmassa]

Also, do you have up-to-date versions of both nn and cunn ?

[lim0606]

@fmassa

Thank you for kind response!

I inattentively disregarded `require 'cunn', since I thought that the code does not have any explicit usage with it.

Despite of the cunn, I got new error messages as follows;

I would appreciate if you help me to solve this issue.

Thank you for your assistance.

This looks like a problem with your model definition, or with your input dimension. Can your forward the input into your model, like

output = model:forward(input)

?

[lim0606]

@fmassa

Thank you for your kind responses!

There was a problem in model definition in ResNet. (I made a bug fix for it. facebookarchive/fb.resnet.torch#37)

After the modification, I applied model:forward(input) to the model, and I works well. yay!

However..... I got new errors with following messages...;

Hi,

Thanks for pointing this out. I had a fix for the error you are experiencing in a pending PR, but I just integrated the changes in b24b0e5 . Could you try updating optnet and check if it works now ?

[lim0606]

@fmassa

Thank you so much for your kind response!

I works! and thus I made example figures as follows
type A shortcut: https://github.com/lim0606/optimize-net/blob/master/tmp/resnet-cls-A.svg
type B shortcut: https://github.com/lim0606/optimize-net/blob/master/tmp/resnet-cls-B.svg

Once again thank you for assistance :)

Best regards,

Jaehyun

Great ! Nice plots btw.
I'm closing the issue then. Feel free to reopen if you meet any other problems.
